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.

The concept is spot on although the geometry of the pivots are completely wrong, The whole Idea of a steady is to have the supporting points as near opposite the induced stresses created by the turning cutter as possible. This steady does not accomplish this, stop the video atr the 13:40 and you will see what I mean
By changing the clocking of the pivots from the 12-4-8 positions to the 1-5-9 and angling the adjustment bolt on the rear arm to about 30° from the angle it is mounted now this will bring the rollers closer to the true pressure points needed over a wider range of diameters it will still be a compromise as all steadies are to a certain point but will be much closer than what he has now

Now off to find a piece of thick wall large diameter pipe!!!! Or, maybe start with a smaller one. Come to think of it, I think I may have a piece of 4" schedule 40.....
