20207, Series O, 13-inch x 4-foot, Catalog No. 34-A, Floor Legs with Friction Clutch Countershaft Drive, 3/4-inch spindle through hole, 1-3/4-8 t.p.i. spindle thread, I've not put any new holes or cuts in the original lathe from when I got her. All the upgrades with VFD and back mounted pulleys was done by bolting plates between the bed and legs. When I found her she was in pretty good overall shape with the exception of serious neglect. I had to take everything apart to clean and oil her. She had some surface rust here and there and her moving parts had to be worked loose, but overall just needed cleaning. I was thrilled to find only about .0005" of bed wear, and I was able to adjust the spindle back into .002" tolerance with ease. Along with her came the original friction clutch counter shaft assembly, and original motor complete with 4 speed stick shift transmission.
