Virtually every modern lathe above 7 inches swing has a quick change gearbox. When trying to get a pitch not listed on the feed/threading chart the options are limited compared a lathe equipped with a full set of change gears. Since I have the CNC option odd thread leads are easy to do. But there are many times that I have a setup in the CNC that I don't want to disturb so a one off part then has to wait a while. I am considering putting CNC on a manual lathe and just switching between manual and CNC. But I'd also like to know what others do when faced with the odd lead, QC gearbox problem. Cheers, Eric
