New user; apologies if I am posting in the wrong forum.
I have a made-in-Taiwan drill press that needs a lefthand threaded nut to secure the pulleys on a tapered spindle.
As best as I can measure, the male spindle threads are EITHER: M22 x 1.5mm - or - 7/8" x 16 tpi. I believe my 16 tpi thread pitch gauge MAY be fitting a little better than my metric 1.5 gauge, but I am not certain.
I can find left hand M22 x 1.5 nuts at McMaster-Carr, but so far, I can't find any source for left hand nuts in 7/8" x 16 tpi.
McMaster-Carr offers the M22 nuts in thick or thin, and in steel (low and medium strength), stainless steel, or brass. If it turns out the actual thread size is 7/8" and not M22, is there any possibility a M22 nut might fit well enough to work?
If I get the thin brass nut, it might tolerate a misfit better than a thicker nut in hard steel, right? And brass would be less likely to damage the male threads on the spindle. On the other hand, the nut itself is more likely to strip, if thin and brass.
Any other options I have not thought of?
thank you
