The cross feed nut on my Atlas/Craftsman 12" lathe has developed quite a bit of slack. That's not surprising, since I have a tendency to use the machine for projects far beyond its design capabilities. I just ordered a new replacement from a supplier on Ebay who is making replacement parts for the old machines. As soon as I get that 3 phase generator you practically gave me wired up and running, I've got a Bridgeport mill stashed away that will take over most of the heavy duty milling jobs my home brewed milling attachment has to do now. Nothing beats having the right tool for the job, even if being able to cobble up a suitable substitute comes in handy at times!
