[How do I?] Making Feed Screw And Associated Parts

if you lap make sure you remove all if the lapping compound or it will keep on cutting. bill
 
If a person were to lap a thread wouldn't one need a female nut that was sufficiently oversize to allow lapping compound into the thread?
I've lapped threads by cutting them so that they are a little bit tight but not so tight they won't fit and then running them with lapping compound until they feel smooth. If the nut will go on at all there's room for the lapping compound, which then preferentially removes the high spots.
