Mike,  I would like to get my hands on a flypress with the type of nut you
describe in the URL noted below.  All of the flypress I have seen that are
currently being imported have a multi thread (4) and a course pitch.  Then
seem to work well but advance at only one speed.  If you can find a used
British flypress I think it would have the nut you describe.
