Hi Guys,
There was also a "Foley" machine that sold for around $400 last year on ePrey from up Queensland way.
BTW Bowling Clubs get their reels done on far bigger and more accurate machines than this one. Those high tolerance reels are done on Spin Grinders which spins the reel at high speed while grinding.
Also reels should be ground with their bearings mounted on the shaft as that how it will sit in the mower and this is what one is try to replicate.
Cheers,
BB
