I just purchaced a used lathe and noticed i am able to move the cross feed if i use a little force.upon inspection it appears the acme screw and nut are worn. I was wondering if any one could tell me how to remove the screw. i removed the dials and the nut but the screw appearas pressed in any help would be appreciated thanks.

got it
I found it there is a set screw under the bushing once removed it comes straight out. -
Standard Modern
Leblonde carrys parts for SM, but brace yourself for the cost of that screw and nut. On close inspection, you may find that it is the nut that has most of the wear. With guidance from Evan, I successfully made a new nut from Delrin, and got a replacement screw from Keystone Threaded Industries?, (Products?) This was a MUCH more economical, (and instructive,) solution.

Brass nut
Thanks, After checking it turned out to be the brass nut that is worn. I lucked out and found some one with an acme tap to make one for me. Thanks againComment

They are a great lathe. Mine cross slide nut is a bit worn, however it doesn't really have any negative effect on operation.
