Wobble center

[RocketQ]

Any one have or build an indexable center for truing points on sneakys? I have been using a steady rest with a bearing around the end of the points to reset the center to get the points to run right. Input anyone???? I want to be able to slide this over the tailstock on my Bludworth saw. Guess it really only needs to be indexable by 0.080. Thinking of using a wood lathe spur and machineing it to wobble.

A boring head like the one in the link with a live or dead center with a straight shank that fits, will allow you to offset as much as 5/8" if you use the center hole. Even more if you use the left or right holes. You can get them with a MT2,MT3, R8 arbors depending on what you need.
Do a google or ebay search for adjustable boring head and you get some great info.

that will work for changing the taper but it will not wobble the end of the cue. The offset needs to rotate with the cue.

Penn State industries small 4-jaw independent chuck made to revolve by mounting on a bearing and Morse taper bar to put into tail stock. These are also sold for machine lathes but are very expensive. Should be able to build your own for around 70.00.

Thank you sir. I was looking at taking a spur and drilling oversized for the Blud saw and puting set screws in to offset. Only a 3/8 pin hanging out there. Thank you sir for the info..

When you get it running true, super glue on a small wood piece on the butt and then drill a new center. Why mess with wobble centers. You are doing the hard work with the steady rest. Why keep having to mess with offset centers.
