(...) Mark, The old hollow brick sounds OK, but I'd want them in new looking black ABS, or dark grey. Besides, once I glue it shut, the world will never know! Trust me I know how to use a dremel. I've seen your work, very nice. I 've also made train (...) (22 years ago, 19-Aug-04, to lugnet.parts.mod)

(...) Well, my Semester starts in two weeks, so if you have any tips I'm all for hearing them! My biggest problem is motivating the Architecture students in my group. The Engineers don't really care what they draw (a widget is a widget is a widget). (...)

(...) It's not just after handling it that you need to worry about. The acid in your skin will leech trace amounts from the surface, and you'll absorb it through your skin. You'd need to go out of your way to poison yourself in this manner, but you (...) (22 years ago, 18-Aug-04, to lugnet.parts.mod)

(...) Yes, always wash your hands after handling solder! (...) I see the melting point of standard solder (63% tin, 37% lead) is 183 deg C. If I held a soldering iron and a reel of solder over an invered brick and dripped molten solder into the (...) (22 years ago, 18-Aug-04, to lugnet.parts.mod)

(...) Lead is usually added in a very small amount to make it flow into fine detail better. It's probably only a few percent lead content, so handling it wouldn't bear anywhere near the same risk of lead poisoning that handling pure lead does. (...) (...)

(...) I know there is tin in it, but lead - dont know. Its melting point should be a little above 100C. A friend of mine tells, that there should not be Cadmium in it, as Cadmium is toxic.
