Revolving Tail Stock Chuck or Rotating Tail Stock Chuck

[jjr2001]

Had to stop the progress on the little steam engine model I was building due to small parts.
This particular shaft has a very small .093" section and another at .064".
Well after one attempt I found that a standard live or dead center would not work,
at least not for me. So I found some ideas using a revolving chuck in the tail stock
to hold the end of the shaft. Seems like a good idea so I made one.

Just used a Jacobs chuck with a 3/8-24 thread and some bearings along with
a MT2 taper blank that I made a year or so ago and some mystery metal. I think
the mystery metal is just some hot rolled steel that was left over from another project.

I turned the parts for an interference fit so that I would have to cool (freeze) the MT2 arbor
for the inner race of the bearings and in the last step the housing was heated with a propane
torch so the outer race of the bearings would slip into it. Worked out great. I figured this was
a one time build and that if it went together properly it would never be taken apart.

The pictures show the story. I used 3 surplus bearings that I had in stock and fired up the lathe.

First use will be tomorrow when I make that tiny shaft.

Cheers, JR
