Slightly OT: tips for fabricating with plexiglass?

Hi, I've worked with the stuff a fair bit...competition car windows, radio gear etc. - even a guitar! Use a sharp, perferably new, bit and drill slowly so as not to melt the plastic. For larger holes, drill a small pilot hole first and work your way up through the drill sizes until you get to the size you want. Don't work on it in the cold, it shatters *much* more easily when cold. Lightly coutersink each side of the hole to reduce stress build-up. Make sure the work is solidly supported on a smooth flat surface with no bits trapped underneath. Practice on a few off-cuts first. All these things found out the hard way :-) Edges can be polished with very fine wet-and-dry paper followed by metal polish or jeweller's rouge. -- Cheers, Stan Barr stanb(a)dial.pipex.com The future was never like this!
