Well I've learned that both my Regina freewheel & my Airlite hub have English threads. While the hub threads "looked" good the diameter was ateensy bit over the standard. Richard at Cycleanalyst in Denver (only 45 miles away) had the proper tools to checck things out and a thread chaser to cleanup the threads. I'm in business again! Thank to everyone who responded to my question.
