It's been a while since I started this thread and I wanted to report that I've had a replacement table from WARCO.

The delay was waiting for the tables to come into stock. Apart from anything else the new tables have a half reasonable manual and if the schematic is to be believed bearings!

This table is MUCH better. I measured the run out at 50mm on a piece of 6mm test bar (from a scanner) in an MT2 collet. I did two sets of measurements - the second after carefully turning the bar by 90 degrees (to make sure the bar wasn't bent).

The first test I saw an error of less than 2 thou (about 0.045mm) and the second test was better with no more than 1 though run out.!

This contrasts to a considerably larger error with the previous table so i'm delighted. Of course the other comments (use of tailstocks etc) still apply if I do something delicate with it.

My thanks to WARCO who have been very helpful and professional.
