[CAUT] WNG parts

[Kent Swafford]

I have been particularly interested in WNG composite parts for their  
potential stability in changing humidity.

These are preliminary observations, meaning some of these things may  
simply be startup issues that will be taken care of with future WNG  
production:

The roughening of the shank is critical to getting a hammer glued on  
so it will stay. The roughening must be longitudinal and not radial  
and must be very coarse.

The resistance of these shanks to twisting is minimal. Do not twist  
these shanks; they will break lengthwise, developing a crack the full  
length of the shank. Be very careful in burning these shanks not to  
torque these shanks until they are warm enough; a gentle touch during  
burning is essential.

I have never been one for tight pinning of the rep lever -- until now.  
The set of WNG Steinway-type wips I have now were absolutely  
unregulatable until the rep levers were repinned.
