That’s a good one, what must i tell you about a Tail stock.

A: Clamping Lever

E: Cross Adjustment

With the clamping lever you can fixate the tailstock on the ways.

When you turn the Hand wheel , the Barrel will be moved out or in.

How do we test that the tailstock is in the middle?

Well that’s easy. We take a piece of round material with a center point on one side and we put it in the machine like this.

tailstock4

Place a Dial test indicator to it and set it to zero.

tailstock5
Then turn your material to the maximum and minimum. Turn it to the middle and set it to zero.

tailstock6

Make a line with a marker at the top of the material.

tailstock7

Do the same at the center side. So when you moves the Dial test indicator from one side ( with the marker at the top ) to the other side ( with the marker at the top ) , then must the Dial test indicator be at zero. Else you must change the cross adjustment.
