Slotting Saw Arbor for Unimat

[PJs]

Went back and looked also...basically it looks to me if you had a 30 and 32 you would be set to do any metrics. Personally I haven't used but about 5-6 on that list but the comfort of being able to maximize the machines capability is comforting...to me anyway. That is a challenge with the split nut/reverse under power but I have been considering after my latest foray into SPT to finally build a crank for mine and do them by hand...obviously long threads would be a challenge but most of my stuff is an inch or under. Your big lathe may be more problematic to reach though. Thanks again for sharing! ~PJ
