Hmm, my chart says a 1" BSC is 24 tpi rather than 20. Does BSC cover multiple pitches in one diameter ?

And does your 1-20 CEI interchange with 1-20 UNEF ?

BSC (CEI) is most common to have 26 TPI, the next most common pattern would be 20 TPI.

After that the thread can have a wide variety of applications including 12, 14, 16, 18, 24 and 28 TPI.

The pitch angle on the BSC/CEI threads is 60 degrees as is (I believe) UNEF.

If this is a one off job might it not make sense to bring it to a shop and have them do it? Even if it costs the same - you could be and back to work quickly

Hi JP,

That would have been a good plan but the crank is back in the rebuild motor which is a might tougher to haul around. I wish the motor guy had noticed it before assembly but that didn't happen.

Oh sure what you're really saying is that you don't want to be Mr. "One step forward and two steps back" like the rest of us /bcforum/images/%%GRAEMLIN_URL%%/jester.gif How about a machinist who makes house calls?
