lathe steady REST Panova _ New

Exactly. Prior to this frame you can see the stock is a rough (probably forged) piece of rectangular stock. The arrow points to the square part. He rough turned it because finish is not important. Since it is a short, tapered length, he probably hand-turned it with the compound rest set at the angle. Under those conditions it is difficult to have a smooth, continuous turning motion as you stop to reposition your hand on the handle to complete another turn. Each pause will leave a "spring" mark. If he used a taper attachment then it was set up lose and backlash (or feed rate) is the cause of the rings. Since the pitch of the rings is so consistent I suspect it may have been power driven in some manner.
