Still doing thinking on my Gingery-esque lathe project-to-be... at the
moment I am wondering about tapers.
http://www.motortoolmanufacturing.co...ications.shtml
Says that I could bore maybe a MT#2 in the stock I have... but just what
kind of minimum wall thickness am I looking at? I know Gingery originally
bored a #1 in his 3/4" tailstock ram, and I think same for spindle as well.
I've got stock up to 1 1/8" dia. (hehe, annealed torsion bar... maybe not
the best for things that apparently should be soft, eh?) which could just
barely fit a #3 with like...nil wall left... but how little is too little?

Oh, and these are pretty precise things too... I have a 0-1" mic (aka
"expensive C clamp") so I could maybe turn some stock to the proper taper
and use that for the reference, but what kind of cheap and easy-to-get stuff
has a more accurate reference? Speaking of which, I'm not going to want to
build my own tailstock chuck...hehe...
