I've got a couple of those. I'm guessing when it comes to using them, though.

Ok. I read the entire thread. Very educational.

I have a 1"x1"x6" dressing stick. Now, exactly how do I *use* it?

Ok.
What kind of dressing stick do you use and what do you mean by "dressing stick"? Seems like the term gets applied to everything that is ever used to dress a stone.

Very nice. A comment, however: it is better not to use snap-action switches where you need precise repeatibility. They seem nice and crisp but they are actually not as repeatible as simple contacts.

I like the swinging toolholder idea.

Beryllium copper is safe as long as you do nothing with it that would generate airborn dust.

A spindle chuck isn't exactly a drill chuck. It threads onto the lathe spindle just as a regular chuck does and has a bore to match that of the lathe.

I agree that there's no point in obsessing over 3-jaw runout, but I find it quite convenient that my Jacobs spindle chuck has a runout of less than .001" over most of it's range. For most purposes I can treat it like a continuously variable collet.
