Nels, have you been reading my mind?????
Just two days ago a wood turner friend of mine asked me if I wanted to do a "fun" project. She's turning wooden beads between tapered mandrels. The one for the headstock has a straight shaft, held precisely in an ER collet. The one for the tailstock locks into a Oneway live center with replaceable points, which use a #0 Morse taper. My task will be to machine this taper onto half the new mandrels, then machine a ~2 degree taper on the "business end" of all of them.
I've been considering how best to implement an offset center on my tailstock ... and here you go, posting an article about a taper attachment that should fit my 9x20 nicely!
Of course, while I'm at it, I must brag on my friend's talent. She's made her own set of mandrels, using 3/8" bolts she bought at Home Depot for raw material. Her idea was to find some steel that was relatively soft, so if she accidentally ran into it with a cutter, it would't damage the edge. And with just a file and her woodturning lathe, she's produced a pretty durn good 0MT taper on her own!!!!
