Hi Ross,

I had someone else machine my ballscrew ends to fit into an angular contact bearing block - that is 16mm ballscrew turned down to dia12 for bearings, then M12x1 for nut, then dia 8 for motor coupling. 3 off cost me £50, and he did a great job, turning it around in a couple of hours whilst I visited relatives.

He was John S from Nottingham - it has taken me a while to realise it, but I'm sure it is the same John S from Nottingham (HobNob man!) who posts on here, so hopefully he'll chip in soon ! I saw his advert for machining services on the Arc Euro website.

Best of luck
