Pretty cool, Marv. This suggests a number of different approaches to making a whole set of lathe dogs that solve the age old problem of 3 jaw chuck runout. A given set would be custom for just that chuck and it's custome worn scroll.. But it's really just an afternoon's work of relatively simple machining. You color code each set for one specific chuck. When the price of a new Bison chuck makes that approach out of the question this approach comes to the rescue. Ed Weldon

I guess I'm not understanding your "set for each chuck".

Since you turn a new point on the center each time you mount it in the chuck, only one is really needed. The dogs only transmit rotation to the workpiece so they can be used with any chuck.

If you would like me to expound on anything, just indicate which ideas and what further explanation you would like. I'll try to answer your questions.

Perhaps a photo of the lathe dogs mounted would help clear it up for those of us with less imagination... Otherwise, I think you have some humdingers there!

Perhaps you can puzzle it out from this photo of a more conventional lathe dog in use...

All very useful tips. Many thanks!
