16x60 Summit. Why rated 16" swing I have not a clue? will swing 20" over the ways, 3" spindle hole. Rapids both directions, power feed on the tail stock, threads US, Metric, Modual and dimeteric pitches. Shown here boring some 5 1/4" tractor sleeves. Not a golden oldie though. I purchased it brand new in 2001 and paid for it with one threading contract. I would quit working on old stuff if I had to get rid of my lathe.
