Air Hammer

[Joseph Garrett]

Carl,
I'm not quite following what you are doing. I guess I need a picture. It's
almost clicking, but must be the hour or the senility kicking in. :-)
Another thing that hasn't been mentioned by anyone is, are you air nailing
the tuning pin WITH the wire attached or without? As I always use a tuning
pin crank to wind the coil, BEFORE I pound the pin, this is, I think, an
important factor. I know that a lot of techs pound the pin first and then
STRUGGLE to get the wire wound on the t.pin. IMHO this leads to beckets all
over the map, so I do it the other way. (It's the way Del taught me.) Good
to hear from you on this subject, as I'll be stringing a C. Bechstein, soon.
Best Regards,
Joe Garrett
