Radio Shack is my source; the selection of colors isn't too good but the price is okay. I don't think you're gonna find stranded wire for use in wire-wrapping applications.

Bert, if it were me, I'd forgo the idea of white glue & water and instead use Future to make sure the decals stick to the model. I'd paint a little puddle of Future onto the model, apply the decal onto that puddle and use the corner of a paper towel to wick up the excess Future once the decal is...

I do quite a lot of home photoetching but I do not use the toner transfer technique, nor have I ever tried printing directly to brass. I would think the fuser unit in the laser printer would have to be very robust to handle anything more that the thinnest brass sheet. In all the reading I have done ...

Personally, I like metal toggle switches like this one. Very solid and reliable.

This is a SPST...

I have no direct experience with this specific paint brand, but fluorescent paints generally need a white primer underneath them. White enamel or lacquer is a great primer. The primer should be matte or semi-gloss to give the acrylic paint something to grab onto. Shoot light coats with your airbrush...

Just to throw out some ideas: You don't necessarily need a rotocasting machine to do a rotocast piece; you can turn it by hand and get nearly as good results. A rotocasting machine is great for mass production, but it doesn't sound like you intend to make a bunch of parts in a short time. Another al...

With the little experimenting I've done with this I've found that using coloured LEDs instead of colouring the strands gives the best colour. YMMV I'll second that.

My original plan was to machine the mold out of aluminum, then use that to make parts out of sculpy. I'm getting the feeling that this isn't the best approach.

I suggest you go to Smooth-on.com and watch every video they have that pertains to mold-making. You will probably find your solution there. You can also go to YouTube and watch all kinds of different mold-making videos. There's no better investment than time spent watching something being done.

I tend to agree with the theory of air in the resin causing more apparent volume than is really there, and then being pressurized with not enough of a reservoir to ensure the mold is filled. Is your batch of resin getting a little old? Does it foam up if you were to try to cure it without pressure?

Yeah, this is fairly common. It's called "flooding" the interior. The LEDs don't necessarily have to be super-bright and you don't necessarily have to aim them at the window openings. You can also use white paint on the inside to evenly illuminate the interior.

Well, it that case you're SOL :wink: But try to reduce the thickness of your sealer coat as much as you can; you could decant the Testors spray and shoot a couple of coats through your airbrush. The thickness would be reduced but the coverage should be good enough to seal in the ink.

Since these are laser-printed, I'd try skipping the decal bonder spray since it's adding thickness to the decal. The surface of the decal will be more fragile and susceptible to scratches, so keep that in mind when handling them.
