Yamaha Repinning Question

[Rob Kiddell]

Greetings List,

	I have the task of repinning a 1974 Yamaha U3 with *very*
inconsistent pins. I have done many a rebuild on older instruments,
but this is my first Yamaha. My question lies in the threaded pins.
Do I acquire larger threaded pins from Yamaha, or ream and repin with
conventional cross-hatched pins? Is there any advantage/disadvantage
to either process on Yamahas? The pins range from very snug (80+
in/lbs in both directions) to non-existent tension. There is no
consistent pattern to the 'looseness', pinblock separations are not
suspected. If I repin with Yamaha threaded pins, I'll need two or
three different sizes, unless I ream and destroy the threaded
grooves. Any replies would be appreciated.

Thanks,
Rob Kiddell
