Watanabe thread size?

[Richard Brekne]

If you need a thread size to fit a Yamaha tuning hammer or anyother 
hammer with the same threading... simply specify this to Watanabe and 
you will get the correct size. They make tips that are perfectly 
compatible with Yamaha hammers, and they also provide one with a star 
they personally tout as superior to stock Yamaha

    Anyone know what threads the Watanabe tip receives?

    The stud onto which the tip screws measures 9.49 mm X 0.85 pitch in
    metric.  I'm guessing that's almost certainly *supposed* to be 9.5 mm.

    9.5 mm is almost 3/8" -- just 0.0013" shy of it, in fact.  A standard
    3/8" with 30 threads per inch corresponds exactly to the stud
    threads...except for the very slight difference in diameter.

    So I'm thinking the 3/8" will work fine.  The tip has enough play in
    it that it should screw on without any problem.

    Anyone know offhand?

    Thanks,
