Myford 33t and 34t gears for metric threads

[Peter SansomParticipant @petersansom44767]

Another radical suggestion is someone approaching RDG, or Myford, about gettign a batch of 34 tooth change wheels made.

Certainly RDG had some about 6 months ago.

Have just sent RDG an email about the 34 tooth gears. If others contact them as well they may get a batch made. If anyone knows anywhere else that can cut a batch, then please approach them.

An excellent idea Peter, I have just emailed RDG as well and got an almost instantaneous response that the 34t are currently out of stock but are expected back in stock in about 8 weeks.

I trained and worked for six years as a scientific instrument maker and I never saw anyone screwcut a BA thread or indeed later in my life of engineering ,thousands of BA threads were cut using split dies and they did not wobble,provided a sliding die holder was used,I can recall ,that in our works some 60 years ago only one job ,a steel 1 BA screw was produced in batches of 2k that used the self opening dieholder. on a Ward 2A capstan, I can never understand why BA was ever thought of though I gather that it was instigated by a commitee and we well know the rubbish committees invent. In the smaller tooth sizes I do not see any problems with running mixed tooth angles together at slow speeds and relative short running time.

The thread form lent itself to instrument making and producing screw threads in thinner sheet (usually brass) material.
