Hello fellow modelers and dear friends.

Welcome to another issue of Mold Lines. Iwould like to give a special welcome to our newaudience. Our club keeps growing at atremendous pace. In our last meeting we had36 members present and this number growswith every meeting. We had a great meetingand many of the models in display were for ourVietnam / Exploration theme, a display that didnot happened. Please allow me to explain. Dueto an unforeseen issue the Downtown libraryhad to remodel the main display area in thelibrary’s lobby. This remodeling would take allof May and part of June. So it was decided atour meeting to postpone our theme exhibit andjust do an open theme display using the fivesmaller

3

cabinets (three in the main lobby & two in thechildren's area) available. Our Vietnam /Exploration display will be postponed for 2018.I am sure many people , including myself, arehappy with an additional year to work on ourdisplay models. On other news we bring youanother complete model by Dick Smith. If youdon’t remember, Dick Smith’s resolution for lastyear was to only work on models that had beenstarted until all started work has beencompeted. That’s one admirable goal, and heseems to be going for it at full steam as thismonth he brings us another Shelf Queencompleted! I hope you enjoy this latest issue.

Until next time.

Model on!!

The Panavia Tornado is a family of twin-engine, variable-sweep wing multirolecombat aircraft, which was jointlydeveloped and manufactured by Italy,the United Kingdom, and WestGermany. The first aircraft weredelivered to the RAF in June 1979. Thereare three primary Tornado variants:fighter-bomber, the Tornado ECRelectronic combat/ reconnaissance andthe Tornado ADV (air defense variant).

TORNADO GR1 MK1

This story starts in 1988. That year

Hasegawa released its 1/72nd scale kit of

the British Panavia Tornado Gr. Mk.1.

I’m a big fan of British aircraft and had

built the Monogram kit of the prototype

aircraft a year earlier.

This new Hasegawa

offering promised all of the

improvements of the newer version of the

variable geometry front line fighter.

Construction started with the ten-piece

cockpit interior, two three-piece Mk.10A

ejection seats and the application of the

six decals for the side consoles and

instrument panels. The cockpit was

painted medium sea gray with the

ejection seat cushions khaki green and

seat frames dark sea gray.

With the cockpit complete,

work started on the wings and fuselage. It

all goes well except for the fact that this

is almost 30 years ago and the fit of the

parts is not what we expect today. That

means filling and sanding almost every

joint. At the time the only filler putty was

Squadron’s Green Stuff. It had one great

drawback; it would shrink when it dried.

TORNADO GR1 MK1

To overcome this problem most modelers restored to automobile bonding putties like

Bondo and one called “Acryl Blue.” The blue putty was lacquer based and had to be

used carefully as the solvent that made the putty spreadable had a tendency to melt the

polystyrene plastic of the kit. Acryl Blue had another problem in that when it dried it

became very hard and was like sanding steel welds.

With these problems, I decided that I didn’t need this kit completed and put

the Tornado back in its box and forgot about it. A few months ago, I came across the

battered cardboard box and decided that this kit would no longer be unbuilt.

TORNADO GR1 MK1

ting camouflage scheme of brown, two green shades and a light tan color. These four

were alright but not interesting. I came across an Xtradecal sheet of 100th anniversary

display aircraft. I used one of the schemes on a 1/72 scale Typhoon from 3 Squadron in

2012. The tail and spine of 2 Squadron’s Tornado was black and white with an interesting

depiction of a World War I biplane along with a large “100.” The rest of the aircraft was

medium sea gray and stood out in stark contrast.

Tornadoes were configured to carry all manner of bombs and rockets but

since this was a display aircraft I armed it with two practice Sidewinders, long range

tanks, a couple of jamming pods and a pair of runway denial weapons.

The ejection seats mentioned earlier were lacking in detail. A little stretched

sprue and a set of Eduard seat belts were all that were needed to bring them to life. Is this

“queen” a pageant winner? Probably not but she’s a lot better out of that dusty, dark box

and standing, complete, on a shelf in my office.

I used 320

wet and dry paper to

“grind” off the long-dried

Acryl Blue putty and

finished the job with 400

and 600 wet and dry. A

little Tamiya basic putty

took care of the small

seams. A coat of Alclad

primer and the model was

ready for paint.

The kit

markings were for three

Royal Air Force

squadrons and one Royal

Saudi Air Force unit. The

Saudi unit had an interes-

Recently while working on my Yardley M19 F1 car I decided it would be a good

idea to apply some weathering to the contact patch on the tires. After all,

when was the last time you saw a CLEAN racing slick? My goal was to add

some texture to the contact patch area of the tires to make them look used. I

started by making several tests and experiments.

Tips and TricksMay 2017

By: Jeff Wallen

The results were mixed, while it

added a nice effect, it was not quite

what I was looking for. I needed

something with a grainier texture.

The Mr. Surfacer was Ok but it did

not looked any better than a sanded

tire. I also tried to use a sponge

and paint, but I don’t like to paint

the tires and the end result was still

not grainy enough.

Test #1

• Apply Mr. Surfacer with

sponge to edges of tire

• Light sanding

• Paint with Tamiya flat

black

Tips and TricksMay 2017

After many attempts, I was able to get totally different effects using Zing Embossing powder.

Test # 2, (Try 15)• Clean tire lightly sanded with 600 grit

• Brushed on a little future at random

• Sprinkled the embossing powder on to the future

• This held the powder in place nicely

• Using a lighter, I melted the embossing powder

• Another very light sanding to flatten things

• Wiped the area clean with water

This time the results were quite convincing! The only thing was that I did not

liked the glossy areas where the future was applied. Rubbing and light

sanding helped, but the difference was not as noticeable. One great thing

was that while the embossing powder looks white when applied, once it melts

it took the same color as the tire. It had a light satin sheen but that was not

bad considering the overall results. I was determined however to find a better

way to make the powder stick to the tired without using future.

Tips and TricksMay 2017

Test # 2, (Try 16)

• Tried water with a brush to make the Embossing powder stick

• Failed to work.

• Rolled the tire on the plate where I had spilled some of the powder

• I was surprised when it stuck just enough

• Hit it with the lighter and, Yay…we were making progress

Now that I had found a way to make the embossing powder stick the shiny

areas were no longer an issue. The next thing was to experiment with the

amount of powder to get the proper effects .The nice thing about the

embossing powder is that it sands off easily even after it has been melted.

12

Tips and TricksMay 2017

Embossing Powder: when you heat the embossing powder it melts and leaves a

shallow bubble texture. See this video on how it is normally used.

https://www.youtube.com/watch?v=9ggsLMPFnyE

I used this product (ZING) in the test. (Clear) NOTE this is a fantastic site to get

your art supplies from. Things like paint brushes and other goodies!

http://www.dickblick.com/products/zing-embossing-powders/

So in summary I think the embossing powder has a lot of potential in this

application. Go a little heavy with it and it certainly looks like rubber picked

up on the track. A light sanding will flatten the surface as the powder is

round in shape.

They do make small heat guns for melting the powder. But it would blow the

powder off the part! Using the lighter was the ticket. Not much heat at all is

needed to melt the powder.

Again if you don't like the results it easily sands off. Then you can try again.

Trust me on that cause I have tested and tested and tested again on the

same tire.
