Impact Hammer

[Diane Hofstetter]

Hi Les, et al.

Not long at all.  The same way I do with the traditional hammer.  Test 
blows, visual and aural checks, and  graphs of my previous tunings before I 
tune them again the next time.

Actually, on uprights I feel more secure about the pin positions when using 
the impact hammer because I have tuned uprights so long with an impact that 
my stationary hammer technique is not as good and I fear bending the pin.

Diane- off post, since it might get long, please tell me how you got to the
point you trusted the placement of the pins with the impact. I've used mine
for first passes, but never trusted myself with second passes.........

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?
