Blueprinting Actions

See post number 8, that's a cat's head being held in that 3 jaw chuck with a barrel held in the Cat's head.

I don't know where you can buy one, I've always just made them out of a chunk of heavy walled steel tubing. They work pretty well for other things besides barrels and actions as well.

You can use them to grip long, odd shaped pieces out away from the chuck, and still dial the work into concentricity with the spindle axis , the cat's head is supported by the steady rest in that application.

I have also made a trying cut on the OD, then run this in a steady rest. This gives you the ability of dialing in much better than you can with a steady alone.

I ended up by welding my truing sleeve to a lathe backplate adapter. Works really well. Just be careful with your welding.
