Impact Hammer

[Diane Hofstetter]

The impact hammers are WONDERFUL on uprights!  I have never had any pain in 
my right shoulder,  arm, or back from tuning uprights with the impact 
hammer, but have in my left hand/wrist/arm from pounding.

It takes a bit of learning to use, especially because we tend to get 
dependent on knowing when the pin has turned from our body sensations, 
rather than just from our hearing, when we use the stationary hammer.  The 
impact hammer learning curve is well worth it.

I'm intrigued with an impact hammer design and am considering purchasing one 
to try it.

Two questions:

1.  Is there a model you'd recommend?  (I'd consider a used one from 
somebody on the list if you've got one to sell -- contact me off-list)

2.  Everything I read says they're wonderful on vertical pianos. I'm 
wondering... is there some reason they're not advisable for use on grands?
