I have an internal grinding attachment for a Brown & Sharpe #13 universal- the ball bearing spindle, straddle-bracket, and then a couple of other bits that I assume are from the same machine since they have the V-and-flat table mount.

Does anyone have a #13 universal for which they need an ID spindle? I thought I would ask here before I put it on ebay. I'd like to trade it to an ID spindle for a Cincinnati #2 T&C grinder, but that might be a long shot.

Secondly, does anyone recognize, need, or know anyone who has use for the other parts? I assume the right angle bracket is a mount for a radius dresser or something. It is marked 625-82-13-146. On the clamps- one is marked 439564.

Thanks,
Tim

I did put a test indicator on the tip of the shaft, and there is about 0.001" TIR. I can't imagine any runout is good, and everything has some. But for those with ID grinding experience- how much would be tolerable before post-truing function is impaired?

Thanks,
Tim

So Hendeyman has spoken for the dresser bracket and Turbowerks for the spindle.

I still have no idea what the clamps are. They may not be for a #13 after all.
