Hello,
I am trying to get my 10L running, and I'm having trouble getting the reverse tumbler gears to mesh correctly with the spindle gear. I have found a couple threads about this but in these cases the gears were worn and loose, and in my case the gears are too tight to engage the detents.
My lathe has the cast iron spindle bearings, and they are very worn. The clearance is about 0.030" in the rear and I think the spindle is sitting much lower than it was originally. Engaging the upper detent on the reverse tumbler will actually lift the spindle about 0.025" - obviously not an option once I adjust the bearings or even if the belt is tensioned. Even in the neutral position, the gears don't fully disengage and the gears will buzz against each other.
I think my only option here is to bore / plug / redrill the detents. But am I missing something? Has anyone else had the same problem?
At what point am I better off replacing the headstock?
