Hi CO, me again,
I studied the drawings and, of course, have a bunch of questions now. My lathe has 18 DP gears from the spindle to the QC gear box. Evidently the SB 9" Model A workshop lathe used 16, 18 and 20 DP gears (18 being the most common) at various points in its long production. Changing the counter bore diameters and center distances will be easy enough.
**Can you tell me what the two 10-32 tapped holes in the operators' end of the main body block are for?
** Also, there is a .3125" hole in the back side with two aligned holes in the outboard side. Is this for a forward-neutral-revers detent? IF so, should the matching #43 holes in the detent plate be on an arc rather than a straight line?
Thanks in advance,
FC
