Finishing up restoration of 1939 36" bed 10R South Bend with underneath motor drive in cast iron pedestal. There is a 1/2 inch threaded hole in back of casting.
In, "How to Run a Lathe", it says:
" Stop screw "E" eliminates play when lever "A" is in the lower position. This screw must be unscrewed several revolutions before any belt tension adjustments are made and must be readjusted afterward"
So this bolt acts as a hard stop when belts are under tension. The motor assembly must weigh 60lbs so where is the play and how do you know how it should be set.
Seems to duplicate belt adjusting screw on front right? Why do they have both?
