Identical to the lathes we had in shop in trade school. It has been some time (14 years), here is what I can recall. I hope it is right. If I remeber correctly:
1) It is belt drive.
2) #3 M/T in the tailstock.
3) The spindle taper I beleive was propritary. Needed an adapter for centers.
4)Threads/feeds many, don't recall exacly how many. If I recall correctly you could cut between 4-244 T.P.I. I remember one time having to re-arrange two gears in the gear train for some reason, can't remember why though. Maybe to obtain such a wide range of threads.
5)Thru-hole is about 1 1/2" or 1 5/8".
6)They were variable speed drives, spindle speeds about 30 or 50 to 2200 or 2400 R.P.M. The hole in the lower left of the cabinet SHOULD have a handle sticking out of it, that was to select high/low speed range. I would find out why it is not there. (Maybe I should have READ the info with the picture BEFORE I typed this statement!!!)
7)The knob in the center of the headstock is for forward reverse direction of the leadscrew.
8)The ones we had in school did not have collet closers on them. I would suspect they are availiable though.
9)Weight, not sure maybe 1,500#.
They were nice lathes, I liked them.
Paying Attention Is Not That Expensive.
