Do you use natural delrin or delrin AF, (delrin impregnated with teflon)? I'd think that delrin AF would be superior for bearing blocks, but I don't know what sort of restrictions you might have for prosthesis.Just Plain Al wrote:At the shop I work in we machine bearing surfaces for prosthetic legs from Delrin.

From what I have read here and other places, building a ventilation system that does not go outside is a pipe dream. You'll find contraptions that use buckets and supposedly filter out the fumes but everything that I have read in previous discussions says they don't work and the room ends up stinki...

The only difference I can think of, I usually wash white metal in vinegar before priming. With plastic I just use soapy water. Also, plastic tends to develop a slight static charge, especially when sanding on it. So to keep dust and cat hair from being attracted to the surface, I'll always wash it b...

The indoor filter in the bottom half of Pat's article here works really well. It eliminates the need to vent outside. We built the test article in a hotel room and sprayed straight lacquers into it, with no smells or fumes escaping at all.

I think I know how to prevent this, coat them in Future. But I don't know how to fix them if they're already on the model. Typically you can use bright sunlight to bleach decals by hanging the sheet in a warm, sunny window for a couple months. But I don't think that would work too well with decals a...

The walls of PVC pipe don't hold glue or paint very well. Which makes sense, you don't want, er... stuff ... sticking to your plumbing. Fortunately there is a fix. The way they make PVC non-sticky is they bathe the plastic in, (I believe), fluorine gas, which chemically treats the surface. Sand thro...

My guess is the salt is pulling the water out of the paint, causing it to cure unevenly. The good news is, this is part of what the salt method is supposed to do. The reason to use salt rather than, say, peanut butter or dirt, is because salt does weird things with the paint. Don't look at it as a b...

Delrin is in the same family of plastics as teflon and polypropylene. It is specifically designed to be non-reactive, and requires special glues to stick to it at all. You could make a good CA bottle out of it though. If you are looking for a plastic that machines well, and can be painted and glued ...

Your list is pretty similar to mine. After base coat I'll put down several effects coats. Then after decals I go with another clear gloss coat. You wrote decal sealer, which I guess is the same thing. Maybe some more effects coats after that. Then washes, all kinds of washes, followed by another sea...

There is a sticky on this subject in the finishing forum, four pages and counting: http://www.starshipmodeler.net/talk/viewtopic.php?t=15835 Read through that, then experiment like a mad man.

You can try wrapping the nose in tape, overlapping the grey area a bit. Then draw the demarcation onto the tape with a good, sharp pencil. Pull the masking tape off, and cut along the mark, (maybe using a french curve as a not-so-straight-edge). Reapply the tape, and paint away. Another trick is to ...

I try to build my models so they can stand up to a good cleaning. Too often in the past I've had problems where even a little soapy water will cause the decals to lift or flake away, small parts to fall off, and delicate weathering to be obliterated. Ideally I'd like to be able to completely submerg...
