Maximat V10P runs out

[JohnHaine]

You need to check the bed levelling, don't try fiddling with the headstock alignment. There is probably a small amount of twist in the bed which can be removed first by making sure the stand is rigidly fixed to the floor, then careful adjustment of the clamping bolts holding the lathe bed down. A precision spirit level is very helpful to test across the bed at various points to make sure they are all coplanar.

Yes, a check with my level shows that the bed has a twist in it, I can shim the mounting cabinet easy enough, will it correct the headstock I wonder?

[Africanimp]

Ok, job done and it took a couple of hours, adding Formica shims until the level read the same at either end of the beds.

The test on the alloy tube run again and the run out is still showing 0.003" , so no change there .
