putting a load on the lathe without doing anything !

[rock_breaker]

i read somewhere that it may be necessary to play with the tooth engagement as your putting the Rack/knob in in order to get it spot on.

My Clausing does that due to heavy load pushing the gears apart. When I notice the noise I pull the back gear engagement lever back into full engagement.
Have a good day

I noticed when cutting the outside edge of a 3" flat pulley in back gears that the back gear knob was going in and out !
sense I have re adjusted that, so that the rack positions the gear at the APEX of it's travel ,..... i have not seen the back gear knob move at all
..... the lathe is noisier in back gears now.... no doubt, but I think it is functioning much better than it was. and I don't hear the back gears flopping back and forth in there now...... though I have not faced that 3" pulley sense.... so it's hard to say !
