My Atlas 12 x 36 is exhibiting some strange behaviour lately. The compound gears that engage the QC box and the idler gear are working themselves loose when I engage the halfnuts for turning. Basically, I can make about 3 passes before the nut loosesns and the compound gears move out of engagement and the work piece gets a nice shiney spot where the bit just stay engaged. If anyone has any idea of what would cause this, I would appreciate any advise. I think the design is awful with the gears directly riding against a washer that directly rides against the nut, but if others with Atlas lathes don't have an issue, then something is just funky with mine.
Thanks, Derek G
