Similar to SJ's suggestion, I have a milling table setup for my lathe which can be mounted on my DP tabletop. This is MK.2... I haven't posted MK.1 here (yet), however, I made it out of a cheapĀ  "two way cross slide vice", which I posted here at LJ (you need to scroll down).

If your first cut is too short... Take the second cut from the longer end... LBD
