By Robrt SavignacThis October marked the first Interna-
tional Summit meeting of Log BuildingAssociations held in Europe. In answer tothe call I put out, representation from Swe-den, Switzerland, Norway and Finlandattended the event. Despite some languagedifficulties,speaking log was our commondenominator and we were able to focus on
thermal performance and other R & Dprojects which are topics of international
importance.As national log buildingassociations we are all found to
deal with many of the same issues.Many individual countries have had
recent struggles justifying their log build-ing programs and methods, especially
with regard to acceptance of industry stan-dards and thermal performance require-ments. In various parts of Scandinavia, theheart of log building is being challenged by
energy performance requirements, thusresulting in testing research data requests.To assist with this R & D, which is invalu-able to the industry worldwide, the ILBAhas made a formal request for any and alltechnical research papers on the structuraland thermal performance evaluations of loghomes from each participating country.Once received, we will then compile thisinformation as a universal resource on loghome construction.The scope of this col-laboration was not limited to the halfdozen participating countries at this Sum-mit meeting, but is open to as much inputas possible.
In light of the spirit of cooperation andthe friendships established, it was moved byparticipants that a European Log BuildersInternational Conference be organized forthe fall of 2003.The ILBA, in collaboration

with the Association of Swedish LogHomes, is now planning such anevent, to be held the last weekend inSeptember, 2003.There will be a two
day pre-conference workshop ontruss systems, leading into a two dayconference, followed by a tour of tworegional visits to the log homeregions of either Norway and Swe-den, or a second option of Finlandand the Baltics. Both tours will hap-pen concurrently, and participants willbe required to register in advance fortheir choice of tour.The conferencewill be held in the Dalarnas region ofSweden, two hours north of Stock-
holm, believed to be the highest con-centration of log homes in Europe.My very brief day tour of the area ofthe fall 2003 conference area, wasoverwhelming with log structuresEVERYWHERE, some dating back tothe 12th century!
During this brief trip to Sweden Ialso had the opportunity to visit acouple of log building constructionsites as well as with a log buildingapprenticeship class. Most log con-struction done in Sweden is of a par-tially profiled log, flattened on two
sides and re-profiled on round sur-faces to ease the scribing process.Most structures are built of either140mm diameter or 200mm diameterfor residential construction.Thenotching found in these structuresclosely resembles the kind of workseen in buildings hundreds of yearsold, a testament to the phrase if itsnot broke, dont fix it.
Many of us are still trying to definewhat works and what doesnt, and yet
there remains technical advances andimprovements in log building systemsthat generate interest and controver-sy worldwide!
It was, however, very curious that,at least in Sweden, round log struc-tures were very rare and not to the
general acceptance of Swedish stan-dards. It seems ironic that those rus-tic elements are exactly what afi-cionados of modern log homes inNorth America are seeking toexpound. I also saw examples of loghomes built from Russian, Estonian,
and Latvian origins, all depicting acommon origin of development.
In North America our handcraftedlog craft is often referred to as usingtechniques ascribed to its Europeanorigins such as the Swedish copeand Scandinavian full scribe andNorwegian notches which are com-mon examples of this.
The tour options available at theend of this European Conference willbe of tremendous interest to all log
builders seeking answers to the histo-ry of our craft, as well as gaining fur-ther inspiration into techniques andbuilding styles. Ironically, I heardround log homes referred to as the

In Salt Lake City and, more recently at Rendez-Vous, Frederic
Brillant presented well-attended workshops on complex roof
joinery using the French Scribe method, which does not rely
on mathematical calculations.We now offer two comple-
menting approaches to log and timber joineryone with an
algebraic approach by Joseph Bartok and the other by Ed
Levin taking a geometric tack (Page 9).
By Joseph BartokAs an amateur mathematician, I am asked now and again by
our local log builder, John DeVries Log Homes, to design jointsfor timber framed and log roof systems. Sometimes, solutionsthat appear straightforward can prove to be challenging. Con-
sider the interlocking truss system shown in the IsometricProjection, Diagram 1.
Two 8/12 rafters meet two beams at each corner of thestructure. Since the faces created by the compound angle cuts
are visible, the adjacent faces must match.Entering the pitches and total deck angle values (Diagram
2) in a spreadsheet designed for this purpose quickly generat-
ed a list of layout and saw bevel angles. Experimenting withsome dowels and cardboard models just as quickly showed
that working to standard plumb and level reference lines pro-duced badly mismatching faces.
This wasnt going to be as easy as it seemed!First, a word about the math.The reader needs some famil-
iarity with linear algebra and trigonometry.The equations nec-
essary for a solution will be given without proof.Any text on
vectors, matrices, or linear algebra has more detail for anyonewho wishes to pursue this subject. In addition, while the theo-ry is not complex, the computations can be tedious.A spread-
sheet to solve the required vector quantities and trigonome-try, or a programmable calculator that can solve matrices, is anasset.
Going back to the problem of matching compound faces:A
plumb line of convergence was not the answer. However, it
seems reasonable that there must be some line, tilted with
respect to plumb, where, with correct cutting, the logs of equadiameter could meet and adjacent faces match.To begin solv-ing this problem, we need to be able to calculate values of
angles for cutting and dimensioning. Normally, anglesexpressed in terms of arctan are more useful for timber fram-ing, since tangent = rise/run and translates directly to meas-
urements on a framing square. Referring to Diagram 1 for defi-nitions of the angles:
tan(HIP) = tan(PITCH)sin(DECK)
tan(DECK) = cos(PITCH)/tan(ROOF)
However, since the subject is linear algebra, here are some
equations initially solved using vector cross and dot productformulas; note that they use arcos or arcsin:
cos(BACKING) = cos(PITCH)/cos(HIP)
sin(DECK)/cos(ROOF)sin(ROOF) = cos(DECK)cos(HIP)cos(DECK) = sin(ROOF)/cos(HIP)
Here is a list of the angles; these would be the standard val-
ues used to frame to plumb and level lines. In this case, the8/12 pitch angle also serves as the hip angle. Diagram 2 shows
the calculation of the pitch angle for the corner plane.
However, we need another set of angles calculated with

respect to a the-
oretical obliqueline to which
the rafters con-verge. (For the
next set of cal-culations, Im
going to call allfour membersrafters).This
line is perpendi-cular to some
plane; lets namethis plane the inclined deck. If the rafters are to meet equal-
ly, their diameters, lengths, and pitches with respect to thisplane must all be equal. Let all the lengths equal one unit, aneasy number to work with.
We also need a frame of reference against which to meas-ure and calculate values for our points, lines (vectors) and
planes.The roof system may be positioned against the mutually
perpendicular x, y, and z axes in whatever manner is conven-ient and simplest, therefore the logs are oriented so that thebeams lie on the +x and +y axes, and the z axis is plumb. Sincethe lengths all equal one, some simple trigonometry (Diagram
3) will show that the feet of our rafters now lie at the co-ordinates shown in Diagram 4.
Subtracting the values of the co-ordinates, beam minusrafter, yields the values of the components of vectors a and b;
note that both lie on the inclined deck.The cross product r =a x b yields a vector perpendicular to the inclined deck (Dia-gram 5). In terms of the components of a and b, r = (yazb -
ybza)i + (zaxb - zbxa)j + (xayb - xbya)k
Now that we have direction numbers that define our
inclined plane, its time to do some checking. In this case, ourintuition tells us it is possible to create an inclined deck that
cuts all four rafters. However, if the inclined plane tilts in amore complex fashion at a compound angle, or if there aremore logs converging at odd angles, we need a better method
of testing our work for accuracy.The components or direction numbers of r are also the
coefficients of the general equation of any plane perpendicular
to r:
1.01624x + 1.01624y - 3.35641z + d = 0
If d is assigned no particular value, there are an infinitenumber of planes defined by this equation.The value of d

determines the specific plane we are working to and is foundby substituting the initial co-ordinates of Diagram 4, ( 0, 1, 0 ),( 1, 0, 0 ), ( 0, -.83205, -.55470 ), ( -.83205, 0, -.55470 ), in turn,
for x, y, and z in the general equation. In this case, the points
all lie on the same plane, and d is the same for all the sets ofco-ordinates substituted. Given a scenario where multiplerafters converge, only four initial points to determine one vec-
tor cross product and general equation are needed to imple-ment this test; the remaining points representing the rafter
feet we need only substitute. If the points do not all lie on thesame plane, the values of d will not be equal.This also meansthere is no possible point of convergence, and it is time to
abandon this attempt at a solution, and try something else,perhaps re-sizing the rafters.
Assuming the results of our tests are satisfactory at thispoint, we can rearrange the dot product equation to give a
formula for the angle between two vectors.
The direction numbers for plumb, unit vector - k on the z
axis, are ( 0, 0, -1 ), and we have solved r.Therefore, the anglebetween plumb and r, which equals the angle between the
inclined deck and the actual deck, is equal to:
arcos(3.35641/ 3.65116) = 23.18011 degrees.
Diagram 6 shows the calculation for two of the pitch angles
with respect to the inclined deck.The values of the roof planeangles are half the total angle between ridges. Using the for-
mula tan(DECK) = cos(PITCH)/tan(ROOF), the deck angleswith respect to the inclined deck can be determined (Diagram7). Much as the deck angles with respect to the actual deck
are used to set saw bevels if framing to normal plumb andlevel lines, the deck angles just calculated are the saw blade
settings to make cuts when working to the inclined deck.
The BACKING angles may be solved: cos(BACKING) =sin(DECK)/cos(ROOF)Calculate the HIP angles using any of:
tan(HIP) = tan(PITCH)sin(DECK)cos(HIP) = cos(PITCH)/cos(BACKING)
cos(HIP) = sin(ROOF)/cos(DECK)
Any of the above formulas, using either corner plane anglesbetween the rafters or the angles between the beams, (usingthem consistently, that is), gives a value for the HIP angle, with
respect to the inclined deck, as 16.16075 degrees.The resolution of the angles required for the two remaining
equal planes is left as an exercise for the reader. Hint:All hipangles are equal; the total roof plane angle divided by two
equals 45 degrees.The equation cos(DECK) =sin(ROOF)/cos(HIP) solves the deck angle. Here is a summaryof the results:The planes bounded by a rafter and beam are
named COMMON Planes, since they are shared by both mem-bers.The remaining two planes are named for members they
lie between (see Diagram 5 and Diagram 7).
In this case, note that the BEAM Plane and the two COM-
MON Plane values are equal, creating three equal sets ofangles.
The inclined deck sets of angles have to meet certain crite-
ria:(1) Since the overall shape of the inclined deck in plan is
a quadrilateral, the sum of all the deck angles must equal 360degrees.
(2) All HIP pitches are equal.(3) All dihedral or DECK angles are equal at matching
faces.
(4) The sums of the ROOF PLANE angles remain con-stant for both sets of calculations.
(5) The sums of the BACKING angles remain constantfor both sets of calculations.
Conditions (2) and (3) actually govern mitre and bevel;meeting these criteria means that cutting the compound
angles will produce matching faces if the log diameters areequal.
Conditions (4) and (5) ensure that the logs conform to the
initial design parameters after the backing angle cuts, whichbrings us to the next topic.
Refer to Diagram 8, Layout of Backing Angles.The view isfrom the foot of the log, looking toward the peak.An imagi-nary plane of convergence passes through each log; these
planes intercept at the peaks to form the line of convergence,or convergence vector, where all the logs meet equally.This

plane of convergence creates a line on the log cross-section,
and passes through the maximum log diameter. Starting at thisline, lay out the complements of the convergence or inclined
deck backing angles, making sure that the angles are on thecorrect sides of the log.The backing planes (or roof planes)can now be cut. Measuring from the backing planes, lay out the
complements of the backing angles generated by the initial cal-culation with respect to the actual deck; again, ensure that the
angles are on the correct sides of the log.There is now anoth-er line created on the cross-section of the log, in this case tilt-
ed at 16.84504 degrees with respect to the line of conver-gence.The value of this angle is the difference between the
two backing angles.This line will become the plumb line, rotat-ing to position when the logs are assembled, and any layout orcutting at the foot of the log is done with respect to this line
using actual deck angle values. Note that throughout thisprocess, the ridge line remains constant, as it must if the roof
is to conform to the original specifications. Diagram 9 showsthe relationship between these quantities.
If you are still with me, that covers the theory. In practice, Idid the first sets of calculations manually, using a programma-ble calculator.This was time consuming and created an
increased chance of error if different scenarios needed to betested; a worksheet specifically tailored for this purpose now
does all the number crunching.All that need be done is enterthe HIP pitches and TOTAL DECK angle, and a set of angles
with respect to the actual deck is generated.A feedback cal-culation then re-enters half the total ROOF PLANE anglecomplements as PITCHES, the sum of the BACKING ANGLES
as TOTAL DECK, and the inclined deck or convergence angles
are automatically calculated.The linear algebra convergencecheck, criteria for conformance to original parameters, and
drawings of layout and cutting angles are all done in seconds.To double check the calculations and make it easier to visual-
ize the final product, I also construct 3D cardboard models ofthe proposed joints.
Speaking of the final product: there was no way to avoid a
little work with a drawknife, but otherwise the results weregratifying.The compound faces converged with little or no
measurable error.A powerful and versatile mathematical toolprovided a solution to a difficult problem; investing time in
mastering these techniques is well worth the effort for anytimber framer or log fitter.

A geometric approach to joinery
9December 2002 #40
Log Building NEWS
By Ed LevinThe following exposition presents
another approach to the joinery prob-
lem posed by Joseph Bartok in the pre-vious article.This alternative treatment
might be dubbed the math lite method,as it eschews algebra and trigonometry
in favor of pure geometry.Apart from reader susceptibility to
math phobia, there are excellent rea-
sons to adopt ageometric
approach.Historically, carpen-
ters have beengeometers rather
than mathemati-cians.While manyof the builders of
the great works oftimber framing
were illiterate (andlargely innumer-
ate), they were tra-
ditionally well versed in the use ofdividers, straightedge and related draw-ing tools.Armed with this simple kit
they could lay out and construct aston-ishing compound/complex structures
without resort to cosines, calculatorsor computers.And we can do the
same.Once the geometry is established,
one can then generalize the problemand devise amathematical
solution thatworks for vary-
ing roof pitch-es, member
sizes andlengths, etc. Butany such set of
parametric for-mulas must be
based on priordrawing and
development of
the essential geometry.
We begin with a quick review of the
essentials: A central square tower iscapped by a regular hip roof.A lower
roof skirts the tower with four 8:12pitch abutting roof slopes alternating
with hipped corners, giving the buildingan octagonal footprint.The building is
framed with logs of uniform diameter.The eave corners and peak of the
upper roof are known quantities. Our
concern lies with the peak corners ofthe lower roof, specifically the log cor-
ner joint where two rafters rise tomeet two level wall plates.The pure
geometry of this joint indicates a fiveor six-way connection, depending onwhether the posts are continuous
through the plates.To reduce conges-tion at the corners, the centerlines of

Spider Plan View Low Pitch Roof 3-D Low Pitch Plan
the inner corner posts and surroundinglower roof top plates are offset in plan
so that the plates notch through andbypass the posts, leaving a four-way
meeting of plates and rafters at thecorner.The issue is how to determinethe correct angles at which to cut the
log ends so that they mitre together[Spider and Spider Plan View].
To make sense of this joint, we skewour perspective, recasting the connec-
tion as a hip peak by building a new vir-tual floor under it (Bartoks inclineddeck), which cuts each member one
length unit (foot, meter, whatever) awayfrom the peak. Redefine the ground
plane to coincide with this floor, and we
have transformed our wall corner intoa miniature, low pitch hip roof [Spider,
Low Pitch Roof 3-D].Before proceeding further with
this analysis, lets revisit the basicsof hip roof geometry.The num-
bered panels illustrate the devel-opment of a hip roof. Panel 1shows a birds-eye view of the
roof.All the information needed toderive lengths and angles for com-
mons, jacks and hips can be foundin the irregular tetrahedron
bounded by vertical sections cut-ting through the midlines of thehip and a full-length jack rafter.
This shape (highlighted in Panel 2)is known as the hip kernel.We
extract the kernel from the roof[Panel 3] and begin the process of
developing or unfolding it [Panel4], hinging along the sides of the
triangular deck plan and along the hip.The fully developed hip is shown with GEOMETRYContinued on page 12

faces labeled in Panel 5. Lengths andangles are identified in Panel 6.Theangles are called out both descriptively
and by their symbolic names in theHawkindale Angle system used widely
by timber framers and log builders.*Relative lengths of parts for an 8:12
regular pitch hip roof are shown inPanel 7.
A primer on kernel development:
Start with the plan triangle, then addthe rise (its the same in both common
and hip sections) by drawing perpendic-
ulars to common and hip runs. Connectthe dots to delineate the common and
hip rafters.At this point you have threeadjoining triangles with the deck plan
sandwiched between common and hipsections.The roof surface triangle isconstructed by arcing the eave length
from the hip foot and the commonlength from the hip peak. Draw lines
connecting these two centers to theintersection of the two arcs and label
appropriately. Note that in the roof sur-face triangle, the eave and commonmeet at right angles.
Referring back to Low Pitch Roof -3Dour reborn hip rafters follow lines CK,
EK, GK & JK.We know from their pre-vious life that angles CKE, CKJ & GKJ
are all 90. By the same logic, we canfind angle EKG via the geometry of the
original lower roof: Panel 8 shows adeveloped kernel for the hip corners.Here we start the drawing with the
known 8:12 hip section (the pitch shedroof commons serve as regular hip
rafters in the hip corner roofs, henceR1=8:12).With the hip section drawn,
you can add the 45-45-90 plan trian-gle, then the section at the common.Since the Hip Run is 12.0000, the com-
mon run equals 1212 or 8.4853which, taken with the rise of 8.000,

yields a common pitch (SS) of 8:12/2
or 43.3139.With deck plan and sec-tions established, the roof surface trian-gle is laid out as per the previous para-
graph. Since this roof surface triangle iscongruent to triangle FKG in Low Pitch
Roof 3-D (and to its mirror image trian-gle EKF), we know that
FKG = EKF = P2 = 36.0399and
EKG = FKG + EKF = 2 x P2 =
72.0798We can further exploit the devel-
oped hip corner to produce a sectionthrough the inclined deck. Joseph
Bartoks unit length hip rafters are too
short for accurate drawing, so lets
scale up one order of magnitude. Fromthe hip peak in the hip corner devel-oped kernel, measure down ten units
along the hip. From this point drop aperpendicular to the common length in
the roof surface triangle.Via trigonome-try, direct measurement or similar tri-
angle proportion, we determine thatthe length of virtual common rafter FK[Low Pitch Roof 3-D] is one tenth of
8.0861, and mark off the distance downfrom the peak on the common length
in both roof surface and common sec-tion triangles.
To represent common BK, we raise
a perpendicular to the rise at the com-
mon peak. Since CKJ is a 45-45-90triangle with lengths of 1.0000, 1.0000and2 or 1.4142, and line BK bisects
CKJ, then the length of line BK is 1/2= 0.7071, or 7.0711 in our 10X scale
model. By connecting points F and Band dropping a perpendicular from K to
BF, we can derive lengths and angles forthe section through the inclined plane,shown at 10:1 scale in Panel 9 and at
1:1 in real world orientation in Panel 10(note the similarity of the latter to
Bartoks Diagram 6).

One other item remains on the
agenda, determination of the backingangles for the hips [see Spider and logcross-sections in Panel 11]. Panel 12 illus-
trates a geometric solution to thisproblem. Using the appropriate devel-
oped kernel, from the square cornerwhere eave and common run meet,
strike a perpendicular to the hip run,then continue on at right angles to thehip length. Centering on the intersec-
tion of these two new lines, arc fromthe hip length down to the hip run,
then connect the free end of the arcback to the eave/common run corner.
The angle between the two lines origi-nating from this corner is HawkindaleC5, the backing angle.
Returning to the original question,inspection of Spider, Spider Plan Viewand
Low Pitch Roof 3-D shows that the mitreangles we seek are equivalent to deck
angle D in the plan triangles 1-8 as indi-cated in Low Pitch Roof Plan At this point
we know the lengths of all the con-stituent parts of the inclined plane hiproof: hip lengths are all 1.000, common
FK measures 0.8086, common BKscales out at 0.7071 and, by symmetry,
is identical to commons FK and KH.From Panels 9 & 10, the rise measures
0.2783, run AF 0.7592 and the lengthsof runs AB,AD & AH are all 0.6500.Plus we also know and/or can easily
determine all the relevant angles.Symmetry of parts also tells us that tri-
angles 1, 3 & 7 are identical, and aremirror images of triangles 2, 6 & 8.The
odd men out are triangles 4 & 5, whichare mirror images of one another.
Therefore we need to develop two dif-ferent kernels for a complete solution.Results are shown in Panels 13 & 14.

TechTALK
By John Boys
Leveling a log in blocks by yourself can bea frustrating experience.This modification tomy level allows me to pin it
onto the level line on theend of a log while I run the
peavey.Years ago I trieddrilling 2 holes in a level
and nailing it to the levelline but that proved to bealmost as frustrating as the
original problem.What makes this modifi-
cation work is the 3" planer blade that is bolted to the side of my
level. By using a lock-washer or a ny-lock nut I can keep the connec-tion stiff enough to hold the blade in position and still allow me torotate the blade to store flush when not in use.To use it, engage theblade into the level line on the top of the log, align the level and pin
the bottom in place with a short stiff nail.When not in use the nailstores on a rare-earth magnet (available from Lee Valley tools) epox-
ied to the level.

Over 20 years ago,we introduced builders to
the phrase, Easyaspie.
When you serve up construction-perm lending for as long as we have, you tend to learn a thing ortwo about what builders like. Our recipe for success has always had one key ingredient: Simplicity. Byoffering one-stop shopping, you keep the customer right where you want them in your office. Thisincludes everything from nationwide financing to one close loans. Custom draw schedules to 12month construction loans for standard and system built homes. And an added benefit to you forbeing an Approved Bonded Builder, custom funding options.

By Dave RogersI had the opportunity and great
pleasure to attend the Rendezvous this
year. Discussions onmany topics were
engaged. MaryMackie brought us
remembrance ofthe School and theenergy that swept
many of us up andcarried us along.
Still does.TheMackie School made available to us the
traditional ways of log building.Not
only the construction techniques butalso the accompanying lifestyle that tra-ditional thinking encourages. Manythings converged at the School, as if the
Time had come for this particularInspiration to be visited upon our
world.Those of us that have read the
literature made available in the last 30years concerning log buildings canprobably trace the path back to some-
one who was inspired at the School, ifnot Allan or Mary themselves.The
introduction of the double bubblescribers has probably led to more inno-
vation than any other single tool. I men-tion this because a renaissance of sortsoccurred in the last 30 years that has
propelled us into a powerful industry.Amodern era of building with logs.
There are two very different ways ofthinking about the building trades. One
way is Forward.Always endeavoring to
improve. Inventing and creating newsystems and pushing the envelope ofideas.The other way is in the Past,endeavoring to accurately portray what
was.This is done with research and thestudy of the methods, styles and the
tools that were used on the surviving
examples.It is one thing to build new struc-
tures with familiar tools. It is another
thing to rebuild the work of buildersfrom the past generations. Fine lines
exist between attitudes of approach tothe repair and preservation of older
structures.Historic buildings were anintegral part of the lives that oncedepended upon them for protection
and shelter.They are all that remain ofthose who built them. Lifetimes are
dedicated to remembering the ways ofhow we got to where we are now.
Historic architects, anthropologists,
archaeologists, historians and those ofus who value and appreciate the effortmade by the workmen who fashionedthe structures that remain on the land-
scape, all share an interest in under-standing and preserving our past, intact.

similar definitions.The idea has to dowith protecting and maintaining some-thing.The Preservation field of educa-
tion has a vocabulary that is quite spe-cific.Terms such as rehabilitation, reno-
vation, restoration, reconstruction,repair, reproduction, preservation, sig-
nificance, integrity, and context all havedefinitions that provide for a moreexact communication and therefore an
ability to define methods and proce-dures for protecting and maintaining
something.The following selected terms and
definitions may help to illustrate this:Rehabilitation: the process of
returning a property to a state of utili-
ty, through repair or alteration, whichmakes possible an efficient contempo-
rary use while preserving those por-
tions and features of the propertywhich are significant to its historic,architectural, and cultural values.
Renovation: to make sound again
any structure involved under the vari-ous definitions hereunder by cleanup,
repair or replacement of deteriorated
detail or structure.Restoration: the process of accu-
rately recovering, by removal of later
work and the replacement of missingearlier work, the form and details of a
structure, together with its setting, as itappeared at a particular period of time.
Reconstruction: the process ofrebuilding a non-extant structure orportion of a structure to its original
appearance through archival andarchaeological investigation.Although
parts of the original structure aresometimes included in the reconstruc-
tion, the process usually involves newconstruction materials.
Repair: the reconstruction, renova-
tion or renewal of any portion of a his-toric building for the purpose of its
maintenance.
Reproduction: a duplication, copy,or close imitation of the original.
Significance: importance of a his-toric property as defined by the
National Register criteria in one ormore areas of significance.An associa-
tion with an event or individual, archi-
tecture or landscape qualities, orarchaeological importance.
Integrity: authenticity of a proper-
tys historic identity, evidenced by thesurvival of physical characteristics that
existed during the propertys historicor prehistoric period.
Context: an organizing structurefor interpreting history that groupsinformation about historic properties
which share a common theme, com-mon geographical location, and com-
mon time period.The development ofhistoric contexts is a foundation for
decisions about planning, identification,evaluation, registration, and treatmentof historic properties, based upon com-
parative significance.Usually, efforts to preserve some-
thing from the past are concentrated
on examples that represent featureswith some connection to what istermed significance. Once the signifi-cance has been established, the con-
text of its significance is determined.These initial considerations lay the

There when you need it
foundation on which a treatment strat-egy is based. It is important to interject
here that a little knowledge in this fieldcan be a dangerous thing.Well inten-
tioned advocates of a certain point ofview can destroy the greater context ofwhat they thought they were protect-
ing. It is also true that one has to startsomewhere and a little knowledge is
better than none.Without the existence of examples
of architecture from the past, we wouldbe subject to a constant cycle ofrepeating design concepts that are pret-
ty to look at but become the reasonfor structural failure.Although bark-on
construction, unprotected extensions,
earth foundations, etc., were commonpractices at one time, we can see thatsuch methods are not done withlongevity in mind. Suffice it to say that
even bad practices have an importantrole and should be remembered lest
they be repeated.
When it comes to questions about
log and timber structures, we, as expe-rienced and skilled builders, can discern,
perhaps better than others, how andwith what tools the olden buildings
were built.The unique aspects ofunderstanding the craft of our trade
are vital to relating to the intent andskill level of the original builder, andtherefore vital to the how to of
repairing parts that have failed for onereason or another.
One hundred years from now, wewill be studied as builders. Some of our
work will need repairs. Questions willbe asked such as: Is this building signifi-cant? Was such and such a good idea?
What went wrong and why? How diffi-cult will it be to do any repairs or
replacement? What method of con-
struction was used? What tools wereused? Is it worth the effort to rehabili-tate?
As long as there are those who
want to ask these kinds of questionsand seek out the answers and learn the
various techniques to repair or replace
in kind, and use the tools of the peri-od, there will be a need for an educa-tional facility to address this soon-to-
pass moment of this culture. Ourresponsibility is to share the knowledge
we have and educate those who areinterested in learning.The ILBA has an
awesome responsibility to make avail-able the education so badly needed. Buteducation must also be an advocate of
freedom. Its strength is in the access toall ideas.The ideas that are sound
endure, the ones that are flawedbecome known as such.The choice as
to which is followed is a personal one.The key is knowledge. Education is anongoing process for the duration of our
lives.See: The Secretary of the Interiors

By Ed ShureA recent project required that we precisely locate
dozens of holes in 1" thick steel plates.A potential night-mare was averted when a steel-workingfriend told us about HougenManufacturing in Flint, Michigan (810-635-7111).
Their Model 10904 Rotabroach is alightweight, portable, magnetic base drillcapable of boring holes up to 138" diame-ter through 2" thick steel plate.The cut-ter, which looks more like an end mill
than a drill bit, has a pencil-pointed pilot which is aligned
with a punch mark on the piece to be drilled.A sensorlocated in the base instantly shuts off the machine if anyunwanted movement is detected.A 1" hole through 2plate only takes about 30 seconds.
This tool can pay for itself in very short order, espe-cially for anyone using steel knife blades for post hold-down or truss connections.

the projects andcommitments forthe upcoming year.This holds true forthe ILBA staff andBoard of Directors.Right now, one ofthe most importanttasks that we focuson is the continuing
growth of the membership in theILBA.
This past year our membership hasgrown substantially and now repre-sents over 500 members.This comingyear we expect to see another sizableincrease due to greater member bene-fits and a stronger international inter-est from abroad.
Each member of the ILBA willreceive even more member benefitsthan last year, including six newsletters
a year, a membership card, and ongoingdiscounts and promotions that weobtain throughout the year for ILBAmembers. Other future benefits wecontinue to work on include insurancepackages for members dealing withissues from company owners to anemployee benefits package. Discountsfrom our industry suppliers shouldalso be forthcoming this year.Watchthe newsletters for these details andother upcoming benefits.
On the enclosed Membership
Application, you can read the list ofbenefits for each of the Membershipcategories.We like to see all new andrenewing members get their applica-tions in as soon as possible.A com-plete, updated membership directorywill be available to all members in theMembers Only area of our Web site.Company members will continue to belisted in the public viewing area of our
Web site.Many of our new members have
been introduced to the ILBA throughexisting members.We encourage eachmember to share the benefits of beingan ILBA member with other logbuilders and professionals and encour-age them to join the Association.Thiswill help ensure that the ILBA will bestrepresent our industry. If you know ofsomeone who is interested in becom-ing a member, please feel free to con-tact the staff at the ILBA office andthey will gladly send out an application
to your referral.Please feel free to contact the ILBA

Research & Development
Committee
R&D committeeis in the process ofdeveloping newproposals for vari-ous funding agen-

demonstrate thelife span and failuremodes of finishesapplied to logwalls. Secondaryobjectives aredetermination ofthe effect of vari-ous sealing materi-als used in the lat-
eral grove on thestate/deteriorationof the wood insidethe long groove(moisture conden-sation, mold/fungidevelopment etc,and the effects of apresence ofthrough-bolts in the log wall after pro-longed exposure to the elements.
It is expected that the proposal willbe submitted to Forest Innovation andInvestment in BC for funding in
February 2003.At the same time ILBAwill be submitting other proposalsaddressing issues from the ILBA wishlist.The R&D committee continues to

Certification Committee
Several years ago, the ILBA mem-
bership decided to embark on a certi-fication process to meet what we sawas a growing demand from consumersfor industry control of standards. Priorto that, the Standards document hadbeen vigorously debated and imple-mented as a core belief of the mem-bership of our association at that time and it still is.
We embarked on a process that,
last year, saw us phasein the Certificationprocess with thePledge. In the absenceof a structured andmandated program,the Pledge essentially
asserts that a builderwill build to the spiritand intent of the Standards and thatthey will inform their clients of theirexistence.This step seemed to be alogical bridge to the next step of theprogram and demonstrated commit-ment to raising the bar in log con-struction.A committee was formed tolook into this in greater depth withthe ultimate goal of bringing backimplementation recommendations tothe Board.The committee has been
meeting and debating over the lastcouple of years and in a recent LBNarticle (Issue 37), had proposed anoverview for Certification andtimetable for implementation.
As the process has evolved,morequestions have been raised than thereare answers for and we, the board,want to proceed with care and cau-tion. In light of the fact that morework needs to be done before imple-menting Certification program, it is the
decision of the board to proceed withthe Pledge program as follows, for theyear 2003.
To be enrolled in the 2003 ILBAPledged Builder Program:
You must be a company memberin good standing. Companies listed inthe following categories can enroll inthis program: handcrafted log homebuilding company, architects, designers,engineers, consultants, and log buildingschools.
The pledge agreement is now part
of the 2003 Membership application,whereby participants complete andsign the Pledged Company portion toenroll in this program.
As a Pledged ILBA Companymember you agree to use the LogBuilding Standards of the ILBA as aguideline to ensure the logwork yourcompany creates is of the highest stan-dards and to inform your clients of
these standards. The pledge fee remains at $200
CDN for 2003. Pledged members will provide
access of the Log Building Standards totheir clients.The standards are avail-able on line at the ILBA Web site at
www.logassociation.org under theResource Section. Each member alsoreceives the ILBA Standards with theirmembership package.
It is recommended and encour-aged that Pledged Members provide alink on their Web site to the ILBAWeb site www.logassociation.org
Pledged Members will be listed onthe Pledged Program page of the Website, along with two listings in theCompany Membership DirectorySection.There will no longer be a
color distinction in the CompanyMembership Directory Section.
Pledged Members will receivetheir Membership Certificate with aseal indicating Pledged ILBA Member.
Pledged Members cannot refer tothemselves or their businesses asCertified. The ILBA does not cur-rently certify members or their busi-nesses.This program is a PledgeProgram.As a pledged member youmay refer to yourself as a Pledged
Member of the ILBA. As a Pledged Member you can beremoved from this program if you arenot meeting the guideline(s) as set outin this Pledged Program.
All other items referred to in LBN37 are under discussion and may beaccepted and implemented in 2004.
We felt it would be premature toimplement the next step in thisprocess before careful consideration ofall the issues. New issues seem to becoming forward on a regular basis.The
Certification committee will continueto discuss and debate and plan for aprogram that they can bring back tothe ILBA membership for a decision.
Currently, the Pledge program isvoluntary and has some benefits. In anenvironment where builders and con-

boring countries opening doors to each other. It will remainan ILBA priority to represent all of our interests, and contin-ue to share technologies and information the world over. Ina world of diminished resources, trees are the answer, andlog structures will continue to live on as long as there arepeople who appreciate fine work and a healthy home.Theupcoming European Conference is an exciting opportunityto meet with the people who come from such an historic
precedence of log construction, right across Europe, and dis-cuss the influences that have affected all of our buildingstyles.
On behalf of the ILBA and its members, we would like toextend a warm thanks to our hosts in Europe for this recentvisit and look forward to working on this International eventwith our fellow log crafters in Europe!

sumers seem to desire something like this, we can get themessage out there about the standards. It gives both con-sumer and builder a standardized reference document but isnot intended to constrain and limit good building practice
and technique but rather to give some structure and defini-tion to it. Some might even see it as symbolic program that isa necessary marketing expense.The bottom line is toincrease awareness of good building practice and bringgreater credibility to handcrafted log building. Even in a buyerbeware world, I dont agree with the notion that a consumerdeserves what they get as an association, we have a respon-sibility to foster an environment of continuous improvement.
It now seems an inevitability that Standards will beentrenched in building codes the ILBA standards areaccepted word for word in the Alaska building code andwere a strong reference document for the Japanese building
code. Discussions are in a mature stage with the new ICCbuilding code people.As log building grows in popularity andwhen standards are entrenched in more building codes, it isincreasingly likely that a third party (like government) woulddemand that log builders be certified. If we arent proactive inthis process, its conceivable that standards will be imposed
without our input and will handcuff us all.A process isalready underway in British Columbia for an apprenticeshipprogram where log builders have been front and center in itsdesign.
We need to hear from as many members as possibleabout this issue when governments, certifying authorities,building jurisdictions etc. come looking for information and
direction, they will look to the ILBA first. Make sure you arepart of the process.
