Several years ago, I purchased taps and dies for 6, 8 & 10 ft Aermotor threads. I googled the product manufacturer (Union Butterfield) and many other brands but could not find 11/32 NS, 13/32 NS or 15/32 NS. Finally called Aermotor, San Angelo, and purchased a 13/32 NS 16 tap but they do not have the die.

Any suggestions as to source for these taps and dies?

Thanks, Larry Chilton

Larry, try: Widell-USA 13/32-16 HSS 701807 This is the information printed on my die and the Widell website claims to be a manufacture of specialty taps and dies. I don't remember where I got my die but I think it was probably Muller Industries. Hope this helps...

Thanks, Ivan, I will check out Widell and Muller.

Larry,

Let me know what you find out, I bought some recently from Aermotor

anyone know the size of tap size for a 12ft Aermotor mast pipe? thanks
