This is about to drive me crazy! I don't know what else to do but ask. I just rebuilt my 1937 SB 9a and while everything looks good and it runs very well, I'm having problems with the gear box selector. This is the old single lever with the 3 position top lever style. I very carefully took the gears out, keeping them placed in the correct order, per the instructions, cleaned, de-burred with a needle file, oiled, and re-installed. The gears will spin on the left most position, but not when the top lever is in the center or the right position. What am I doing wrong? I'm trying to cut the inside threads for a spindle thread protector, but even when the back gears are engaged, I have to "help" the chuck to get it to rotate.
Thanks in advance,
Tim
