Happy New Year

From the Editor

Hi Everyone,

Happy New Year! I hope you all had a great holiday and

were able to take time off to enjoy family and friends. I’d

like to thank Tom Fritz and Deb Day for hosting our an-nual holiday get together on December 7th. 22 members

attended the party and it was a lot of fun as usual.

Things have been pretty quiet in the Model A world over

the holidays, but I have been able to get both the tudor and roadster out for some exercise. I think the weather is

about to get cold and snowy for the next few days, so it may be some time before the cars see the light of day

again.

Although winter is upon us, we still have events scheduled including a breakfast hosted by the Hardy’s, Outwaters

world famous chili cook off, our annual planning meeting and the LVMAC joint Model A event in Hellertown. Check

out the calendar of events for more details.

Our newest members are Ken and Judy Nygard. They are

long time friends of mine, and Chuck invited them to at-

tend the Road Kill Rally. They had a great time and de-

cided to join the club.

There is an extensive, well written and researched article by our own Neal Frank in the newsletter concerning after-

market carburetor floats for Model A’s. Neal did a lot of original research and experimentation to determine the

suitability of these floats. Part one of his article appears in

this month’s newsletter.

Finally, there are still a few of you that haven’t paid your

dues yet. The are due by the end of the month, so please

be sure to get them sent to Peg ASAP!

ues, the larger the number, the less buoyant the float.

Table III

While the initial test data

suggests that the targeted

Study Float was the least

buoyant of all the tested

floats, an objective tech-

nique calls for pursuing

alternative methods, to sub-

stantiate provisional findings. With this in mind, a fourth test was conducted

to substantiate or refute the findings of the second and third tests. The fourth

test, again meas-

ured buoyancy

(float density),

however, the calcu-

lations were based

upon a different

principle, that being

Archimedes’s

Buoyant Force.

Essentially, the

principle states that

when an object is

submerged (not

floating) in a fluid,

the fluid exerts an

upward force on the object. This force can be measured and again, was the

basis for test #4. For further clarification, please refer to the following picture

which shows a float, submerged in water. A test line runs down from the float,

through a pulley and redirected, back up past the float to a scale that measured

the upward force, as exerted by the fluid (water), upon the float.

The unit of measure used to represent the buoyant force was the gram, as dis-

played in the following table, number IV.

To interpret the data as displayed in table IV, the larger the number, the greater

the buoyant force exerted on the float. With this in mind, the float with the

greatest buoyant force was the original Holley float at 23.47 grams. The float

(Archimedes's Principle)

Table I.

The second test in the protocol was

to determine the volume of each

float. Simply put, volume is deter-

mined by submerging an object (in

this case, the floats) into a graduated

cylinder filled with a fluid, and,

measuring the amount of fluid (in this

case water ) that is displaced by the

object. The unit of measure used to define the displaced fluid is the cubic cen-

timeter (cc). Please refer to the labeled picture for a graphic presentation of a

volume test, utilizing a float. The volume test results for this study are dis-

played in the following table, number II.

Table II

With the key values, mass (M) and

volume (V) determined, the formula as

displayed on page two, top of column two, can be employed to determine the

density (D) or buoyancy of each of the study’s floats. Utilizing this formula,

the following third set of study values were determined, as presented in table

Christmas Party

December 7, 2014

Hosted by Tom Fritz and Deb Daye

This years annual Christmas party was a huge success! With 22 members in attendance there was lots of good

cheer to go around and everyone seemed to enjoy them-

selves. We even had weather that was good enough for

some to bring out their trusty Model A sleds. (It’s funny

how those that come the farthest bring their A’s ). There were 22 members in attendance and they included our

hosts, Tom Fritz and Deb Daye, Tom and Eva Burrell, Doug and Gail Pyatt, Dick and Bobbi Bettle, Bob and Ber-

nadette Outwater, Ed and June Schwartz, Chuck and Deb Savitske, Don and Lorraine Fox, Ed and Peg Hardy, John

and Donna Cawthorne, and finally Diane and me.

There was plenty of time to socialize before our meal. The

restaurant does a great job and has held the line on costs

over the center, top surface of the

float’s shell (see test floats as dis-

played below-note the bridging

on the center and

left hand floats

The boxed arrow

within the photo

points to a

bridge). The

bridging was only

found on older

versions of the

float, including a

’27-’28 original

Zenith, ’28-’31

original Zenith,

’28-’31 original

Holley, and, an older, aftermarket version. Both newer, aftermarket floats did

not have the noted bridge. It is thought by some, that the bridging is a weight,

added during manufacturing, to maintain specified weight standards. B) The

second caveat is a qualification, pertaining to the ’27-’28 Zenith float, which is

shaped differently than the remaining floats. Steve Pargeter, in his Zenith

Model “A” Carburetor, Restoration Guidelines states, “...There were two sepa-

rate float designs...The early design had a small top area above the solder joint

and a large bottom section. The later design was reversed with the large area

above the solder joint and the smaller portion below the joint”. 1

2) Static Testing of Floats—Raw Data:

The second phase of the study was divided into four static bench test subsec-

tions. The first required the weighing of each float on a laboratory’s elec-

tronic scale (the actual scale utilized for the study is displayed on the second

page of this article in the upper right-hand corner). The unit of measure util-

ized for this study was the gram—for those not familiar with this term, think

of it this way—one gram equates = 0.035273 ounce, or, approximately, the

weight of one raisin! Using this logic, there are 28.3 raisins, or grams, to the

ounce. The weights (mass) of each float as determined by the study’s scale are

displayed in the following table, labeled number I

The six test floats, tagged and secure in their container.

The study float is located in the top row, far right corner.

viding the necessary fuel for an internal combustion en-

gine to function. Too much fuel may result in a rich en-

vironment, with its rough running, smoky exhaust,

fouled spark plugs, cylinder

wall washing and potential

engine failure. Conversely,

too lean an environment may

result in engine stalling, in-

sufficient power and, as

above, potential engine failure. Intermittent fuel flow is equally troublesome,

as the engine’s idle will roll or oscillate, leading to difficult stop & go’s, and,

stalling at the most inopportune moments, including dead engine cornering

scenarios. Finally, an engine compartment fire

is not out of the realm of possibilities!

On the topic of carburetor floats, a well estab-

lished and respected Model A expert ex-

plained, “…to date, you never know about a

carburetor float, especially when dealing with

after-market versions. Sometimes they seem to sink like a rock in the carbure-

tor’s bowl, causing all sorts of performance problems!”

Float Study 1) Physical Examination/Comparison of Floats: The first phase of the study called for the physical examination of the floats,

using micrometers that measured to1/1000th of an inch. In advance of the

measurements, the floats were cleaned for surface impurities, by virtue of an

acetone bath. Next, each float was subjected to a 180 degree test bath to en-

sure the functional integrity of each float was not compromised. Finally, each

float was measured at a set of predetermined, strategic points and the measure-

ments recorded.

Once the measurements were recorded into a table, they were compared to the

standards established by Ford blueprints. Aside from the following caveats, all

the floats satisfactorily met the standards, within a few thousandths of an inch.

Inasmuch as the findings of this segment of the test were insignificant, the ac-

tual findings have been omitted from this report. The two points, worthy of

comment were: A) Of the six floats included in the study, four floats displayed

a bridging shaft that spanned from one-side of the floats hinge bracket, to the

opposing side, and are located at the apex of the bracket’s triangle, directly

when an object is

submerged (not

floating) in a fluid,

the fluid exerts an

upward force on the object. This force can be measured and again, was the

basis for test #4. For further clarification, please refer to the following picture

which shows a float, submerged in water. A test line runs down from the float,

through a pulley and redirected, back up past the float to a scale that measured

the upward force, as exerted by the fluid (water), upon the float.

The unit of measure used to represent the buoyant force was the gram, as dis-

played in the following table, number IV.

To interpret the data as displayed in table IV, the larger the number, the greater

the buoyant force exerted on the float. With this in mind, the float with the

greatest buoyant force was the original Holley float at 23.47 grams. The float

Happy New Year

From the Editor

Hi Everyone,

Happy New Year! I hope you all had a great holiday and

were able to take time off to enjoy family and friends. I’d

like to thank Tom Fritz and Deb Day for hosting our an-nual holiday get together on December 7th. 22 members

attended the party and it was a lot of fun as usual.

Things have been pretty quiet in the Model A world over

the holidays, but I have been able to get both the tudor and roadster out for some exercise. I think the weather is

about to get cold and snowy for the next few days, so it may be some time before the cars see the light of day

again.

Although winter is upon us, we still have events scheduled including a breakfast hosted by the Hardy’s, Outwaters

world famous chili cook off, our annual planning meeting and the LVMAC joint Model A event in Hellertown. Check

out the calendar of events for more details.

Our newest members are Ken and Judy Nygard. They are

long time friends of mine, and Chuck invited them to at-

tend the Road Kill Rally. They had a great time and de-

cided to join the club.

There is an extensive, well written and researched article by our own Neal Frank in the newsletter concerning after-

market carburetor floats for Model A’s. Neal did a lot of original research and experimentation to determine the

suitability of these floats. Part one of his article appears in

this month’s newsletter.

Finally, there are still a few of you that haven’t paid your

dues yet. The are due by the end of the month, so please

be sure to get them sent to Peg ASAP!
