Internal- / cup-center

I often end up with the need to finish spindleturnings after they are parted off, and sometimes pointed, so it is impossible to use my regular livecenter.

I have tried to make some accessory to fit my livecenter like a cup with an internal cone, but I can not seem to make it good enough to avoid some shakes and vibes.

Can anyone give me some advice as to what is out there, in the form of readymade cupcenters?

It would need to be fairly heavy duty. I do not want aluminum.

Not sure what you'd gain from a cup center. Are you already using a chuck on the other end? That's what I do when I am parting to null at the tailstock end. That, and a steady would be the best, as I see it. Part to ~ 1/4" and then trim with a knife.

My Nova allows fitting any shape wooden piece at the tail end with a bolt through it, but I tend to use it in a "male" configuration for holding center on hollowed goblets and such. I have a cup design for inside-out turning, but normally I just leave a bit of extra wood when I know I'll have to part a spindle. They also make a metal cup, but that's used pretty much the same as my wooden ones..

One is to hold the work in a chuck, and use a steadyrest for the "tailstock" end. Doing that, you can actually turn any shape you want on the end--a ball, a point,a finial.

I also have a Morse taper on which I have installed a ball bearing. I can turn a wasteblock of hardwood that presses on the ball bearing, and is shaped to hold the tailstock end of the work. It works fine, as long as I take light cuts.

Hi George, Comforting for N3K owners to see your reference to "My Nova". A long tailstock drawbolt is a good idea. Thanks and keep 'em coming.

BTW, I've seen showoffs (not me, of course) loosen the tail center on small spindles and use one hand over the end to hold and the other hand to finish off the spindle's tip. Easily recognized by their eye patches and missing teeth. :(

one in Ol' Blue is now in the big guy, since the one that came with him,and the spur center, BTW, are best described as POSs. Tough to believe thesame company makes the one above.

Did get a pin chuck for the 3000 from Best Wood Tools. He does beautiful machining. Picture on the owners' group if you'd like to see it. Highly recommended roughing aid. Keeps me from having to worry about ruining this gorgeous mug with flying timber.

George, I'd hate to see your blood pressure if Nova's aluminum faceplate and indexing plate (yeah sure) came with the "big guy". An insult to all decent POS.
