Lol! Wtf!
Lynn,
I wonder if there is something odd about the shaft in my hands (That doesnt sound right LOL!)like it was modified but it doesnt look like it. You are right it makes perfect sense that it would be 16 pitch but the 16 pitch nuts I made dont fit. Plus like you have stated 18 TPI is very very strange but look at my pics. I have attached 4 pics one shows that the shaft dia clearly is 1/2" dia. One shows how far off 16 TPI is using a thread gauge. One shows that 18 TPI is pretty close and would likely work. Lastly a Metric thread gauge with 1.5 mm Pitch looks right on the money but that makes no sense to me.
