How to Correct Run Out

Put a leash on it to stop it running out!

What are you talking about?

The question is not understood.

As I interpret it-

- You are supporting the shaft on two V blocks (presumably at the journal diameter)

- You are rotating the shaft on these supports and checking the run-out (where ?)

- Assuming the V blocks are in good condition, properly selected to the required diameter of shaft, well clamped and are well aligned , the method must be acceptable (subject to the tolerance that have been put)

- If the Run-out is on the support postions themselves (is on the diameters that are supported on V blocks - either any of the above are by-passed. The other possibility will be that the shafts themselves are wrong.
