[pianotech] Re: wood - was: removing key pins

[Keith Roberts]

Thanks David,  WAS in the home repair business. I am loving the piano trade
and it is keeping me reasonably busy. I sometimes trade a friend/contractor
who has a cabinet shop with some really modern equipment, big Simi planers,
self feed shapers, joiners, face frame nailers, routers, chop, table, band,
and radial arm saws, drill presses, air tools, welding equipment. Access to
tools is important. I haven't convinced him to try and build his own piano
yet. Maybe someday. Sure would be fun.
