Another good machinist in addition to those mentioned by Matthew
Caulfield is Ralph Schultz (tel. 1-952-873-6704).  Ralph has over
twenty years experience working with mechanical musical instruments
and specializes in the repair and restoration of music boxes and
tower clocks.  He is perfectly capable of everything in between those
size extremes.

Ralph has built himself a well-equipped machine shop and is capable
of cleaning, polishing and plating parts when needed.  Some of the
work he has done for me includes replacing missing gear teeth, making
replacement gears, machining castings, nickel plating, and copying
an entire tracker bar assembly.
