I've done this many times over the years. It's kind of adjusting your machine on the fly! To get the taper out of the part you are cutting on.This will get me tossed from this forum I believe, so be it. EVERY PART TURNED IS A TEST BAR , if the part is small at one end and big at the other adjust the machine or your tooling choices. .....snip........k
Maybe I am not understanding the concept of the test bar thing...
Unless the test bar allows a user to preform static indications for finding the tapper
Then I would ask, is there a difference, chuck up a chunk of round bar, cut measure and adjust if necessary, repeat until true?
For a hanging storage container, a suitable length of PVC pipe, an end cap, a threaded adapter and threaded plug. Screw an eye hook into the threaded plug and you've got it.
Daryl,This sure made dialing in the new lathe faster than a two collar test!
