I wonder if Shox Dr has any more geared motors for one you could get.I have a simple manual turntable which clamps in the vice, I don't use it much though, there's a bit of a knack to turning it with the little finger as you weld round smaller diameters are the tricky ones, keep meaning to build myself a powered one but never have time.
I've probably still got all the makings for one, I used to make and work on them, the smallest one was for turning ford pulley hubs on a semi automated mig welding set up, the biggest one was set up as an engine turner to manipulate a diesel locomotive engineI wonder if Shox Dr has any more geared motors for one you could get.
