[Hallicrafters] SX101 MK2 Resto (ref URM-25)

I found the note on the gears from the Agilent list. I'm still searching
for the detail on the stock gears that need machining but it may have
been on the HD that got bit by a lightning strike.  I seem to remember
the only machine work required was reboring the shaft hole and
possibly one of them needed to be thinned slightly.  A six pack  and a
friend with a lathe a should get that done or if you're careful a drill press
could work in a pinch.
