Hi
I need dimension of this part to made new, because in my columbia is missing this part.

I think you might have better luck trying to buy an original part than duplicate it. Some of those old threads may not be standard (thread profile and also pitch) today, and a good machinist would need an original part anyway to use as a guide to exactly duplicate the old thread dimensions.

Ron Sitko has them.

I have proffesional cnc machine i made identically.
