I have found that Midwest Products sells single PVC sheets that are great for vacuum forming.  I have found green, blue, yellow, red and clear in .005, .01 and thicker.

Just FYI.  I buy them at my local art supply store - Blick.

Alfakilo,
How about using tinted acetate sheet and just vacuforming that over a plug.  Colored Acetate Click Here


This would be the best answer but finding the plastic is the problem. In some cases, the cost was too much, also don't need 10 multi-color sheets when I only need the blue one. I'll keep looking!

...Interested in how you managed the green, beige, and dark tissue joints. also interested in how you do tissue over tissue...


First, the whole topside was covered in the base color of "tan" tissue. The bottom areas were covered in grey tissue. I then brushed on a coat of thinned dope to help protect the tissue when I start applying the colored tissue.

An example of tissue joints is the green/OD two-color area just ahead of the stab. Two pieces of tissue were placed on a cutting mat with an overlap. Then the joint curve was cut into the overlap so that the two pieces would fit together.

Most of the camo pattern was done by cutting out a green or OD piece and then attaching this to the tan tissue.

I used two methods of attaching the tissue. The green nose area, for example, was done with strips of tissue the width of the stringers glued on with an Elmers glue stick. Strips were used because of the difficulty in getting tissue to lay down over compound curves.

Other areas were attached using a thin mix of Aileens Tacky Glue and water (at least 50/50, usually more water than glue). Aleens dries clear. After the tissue is cut to shape, lay it flat on the model (I put shiny side down). Use a paint brush to start applying the glue mix and smooth out the tissue as you go along. Use care not to press too hard since it's possible to rip the wet tissue. I use the brush to smooth out bubbles and wrinkles as best as I can. I like this technique because as the colored tissue dries, it also shrinks a little helping to get a smooth finish.

It's also possible to use both glue stick and Aleens together. Attach the tissue first with the glue stick and then follow up with a brushed on coating of Aleens to get a smooth and tight finish.

Dan - Great work all around, tissue and tissue cals very well done and that landing gear, great stuff. Looking forward to any flights.

AK - Looking really great and your tissue work is also top shelf as always. Interested in how you managed the green, beige, and dark tissue joints. also interested in how you do tissue over tissue, my more difficult task to do without bubbles.

Both look really slick, Alfa!  I really like the camo on the T-Mustang...

Keep it up!

Getting there with the A-1 and Turbo Mustang. Clumsy hands managed to break both wings, requiring a little innovative surgery!

Still trying to get a dyed canopy for the A-1, this idea isn't as easy as it seemed.

Very nice and the canopy is every bit as good looking as a plastic one (and easier to make!).

Looks great Dan - I was wondering how you were going to do the aft canopy.  Very simple and effective.  Good luck with the flights - post some video if your cameraman is available.

Dan...she's a real beauty.  Your canopy is fantastic!!!!  Does honor to the original intent!!! Looks great too!!!  As far as antenna staff you might want to try some thin acetate like shrink wrap etc.  It can be glued in place with canopy glue or cyanoacralate and will remain flexible to avoid hanger rash and possible hard landings.

All,

Got the canopy done, touched up the landing gear etc. and added the antenna.  The canopy frames are just painted Tamiya yellow tape.  It can go around curves pretty well.

All we need now is the prop and thrust button and she'll be done!

Cheers,
Dan

I've been working on the Comet today.  I didn't like the nose and decided that the rear of the fuselage is too narrow for a pusher prop.  So I redesigned the nose and will be making a clear plastic prop from a peanut butter jar.  I'll rig an adjustable thrust on the backside of the noseplug to adjust thrust with an aluminum plate and screw.  I like the new much better and will have pictures tomorrow after the putty has setup and been sanded.
