Finished it up about an hour ago , now waiting on some JB Weld on the Y axis DRO scale stationary mount to cure . My biggest worry was the alignment of the reworked nut would be off . But it runs smooth as silk thru the entire range . Dovetails on X are a tiny bit tight at both ends , but not enough to matter - and from now on I'll be copying Bob and moving the vise around instead of always setting it in the center . Oh , and backlash is ZERO now .
