Recently? cut new aluminium H/L headstock gears, I replaced the nylon gears to steel some years ago,?
after breaking several sets, the?steel worked OK but were very noisy.
The new "ally" gears cut are a smidge larger in tooth contact to take up the back lash between teeth. Hope to strip the lathe down and fit gears when it gets warmer, to cold here to tinker at this moment.
