Back when I was taking modern physics (elementary quantum mechanics and relativity), my prof told me something interesting. Anything you heat up will glow with the same color (spectrum, really) at a given temperature. Hmmm. I wonder if the professor had any experience with melting (pure, as in not ...

Might be a good idea to mention if the collets and wrenches are included. Without the collets, the head is of no value.
It takes a lot of practice to make things that work right out of the gate. So many things to keep track of, and it's all too easy to miss a detail or two. Nice thing is, it's all experience, so you should be improving, and I expect you are. That's pretty work. You'll get better about little things l...

Pretty much any machine with a round column would be questionable for use as a mill. That's not to say that they don't work, for they do, but it's reasonably easy to cause the head to move under a heavy cut, plus orientation of the head is lost if it has to be moved. All in all, a rather poor design...

Rob, Is it possible that these engines were in California in '90? I recall seeing them, or a pair just like them. I think at the Golden Gate Live Steamers, but I'm not sure. About the same time as the IBLS meet in LA. I was totally impressed with the reality they projected. One had to look to ensure...
I own one of those levels. They are not known for remaining flat, as the relief in the casting and resulting finishing of one face causes internal stresses to be uneven, eventually resulting in the base curving. It's not a lot, but it's more than one should consider acceptable. As has already been s...
