Started blanking out the cross feed screw last week and almost finished today until my 9" South Bend lathe crapped out on me. A babbit bearing seized up on the counter shaft next to the large flat pulley. Get to this later.
For the cross feed screw, started out with a piece of 1045 T.P.G. material 1" diameter. I thought it was Stressproof, but it did not cut as good. But that's okay, it'll make a nice replacement screw that will last several life times to replace the original that is probably made from 12L14 steel.
Since this cross feed screw has to be turned down from 1" down to .625" on each end and a short section in the middle turned to .906", it has to be roughen out first. Before doing anything, Center up and center drill each end. I start out by roughing the longer end first. Leave it about .070-.080" big on the OD. Let cool with the live center still holding the end. Flip the part to the opposite end and rough it down to .070-.080" oversize. Again, let cool. Flip to the other end. Check runout, should be close within say .005-.007" TIR. Any more than this, I'll discuss later on handling this. Getting late, I'll add more tomorrow.
Here's a few pictures. Darn, I didn't take any pictures of it being rough out. Sorry.
