That seems about right, perhaps a bit earlier on the casting sand and 
Gary G's

Indeed.

I don't think so Ries.
The early hammers , at least,  had low RPM motors..1100 if i recall 
right, which are built  with different armatures and windings.

Think Gary G  and Peter Prunuske and some others ended up going over to 
1800 RPM American motors and a jack shaft set up, to slow them down.

Doubt Gary's lasted a year, including the capacitor replacements.

Recall Bondi mentioning that.  Your economic logic is what drew us to 
them in the first place.
Ken Rogers, who'd traveled a lot in the far east, said he had seen some 
that survived very heavy use and  awful neglect for a long time.
Told a story about preparing them for seasonal flooding by routinely 
hoisting the motors up,  and placing them atop the hammers till the 
water receded.

Plus, another 5 grand or so in transport, footings, and wiring.
