It was a very well set up shop. I never felt like I was in any danger. Of course we did have a small amount of triple distilled mercury around. Perhaps I wasn't sufficiently worried about that. The school went to was run by a tube bender that all the other tube benders were in awe of. A natural. Not that she got that good overnight. > I've also wondered about how much vacuum equipment is really necessary; some > books suggest you need to get well below 50 microns to get a good tube. > That's way outside my budget and garage space. Haley had a diffusion pump but never bothered to hook it up. She did have all the latest digital thermometers and what-not. It made processing a breeze. The shop was very large. You could park eight or ten cars in there. Twelve foot ceiling at least with lots of chicken wire holding finished pieces.
