Boring Head Method - Taper Turning Method

I meant to write "show up".

Sure, on a new lathe. My SB 10L suffered the abuse of trade school students from 1965 to 1991 and every alignment test gives a different result. I have to take and measure several light finish cuts to sneak up on the proper diameter.

yes, you can, and it is even easier with a "Blake Co-Ax", since you can lay the anti-rotation lever against the bed, and start the spindle rotating in back-gear and slowest RPM available. Then you watch the needle wiggle (with the face facing you all the time) as you adjust the tailstock offset screws to a minimum wiggle. (A brand new high quality lathe will have the tailstock center slightly above the headstock center to allow from wear. For a long time, it will wear towards even better before it starts getting worse. (And a very slight vertical offset won't make much difference in the workpiece diameter, especially if the workpiece diameter is 0.250" or greater.

And the Blake Co-Ax works well with perhaps 10-12" between headstock collet or chuck and tailstock ram socket.

Enjoy, DoN.

But they did show up, slack time so they did their work and still had time for "inspection".
