Whacking

[Avery Todd]

David,

There's a description of a "jig" type of thing that can be made for this 
purpose.
When I became the CTE here in Houston, I had Ron Sanford make one for
me according to the directions in the testing information book.

That info is at the school and I'm not but if no one else posts it in the 
meantime,
I can probably get it to you tomorrow. I need to go tune one Sunday anyway. 
:-(

I agree with Phil. It DOES give a considerable whack. :-)
