Well what can I say but thanks again John, Irving

Grinding the end of the shaft down worked a treat and was far quicker and easier than my suggestions.

In hind sight it was the obvious solution but having some say "yeah I've done that and it was fine" just gives you the confidence before you potentially turn a working bit into scrap.

Going back to the bearings I have put the preload on them and it is still smooth but there is a definite bind/rub on one point of the rotation, does this sound like a problem?

I have read on John Stevenson site that the bearings are hand marked with the precision and the high spot so they can be matched. Before i strip it all down again dose this sound like the solution?

Thanks again and thanks in advance
