714 forum posts 414 photos	I was wondering if there are any Unimat SL users on the Forum. I am making a tailstock support for my Proxxon/Emco Dividing Attachment set-up. I was hoping to use the same size centre mounting diameter at the Unimat SL, which I think was 7mm or slightly over. Can someone confirm this size for me?
