At the annual Freemont, Ohio Bike swap meets he had a pedal grinder set up outside his van
(or was it a VW Microbus) to demo the process.
The vehicle was completely packed w/ bikes to where there was little room left for him & his wife.
I already had a mirror i'd made so didn't buy one of his but I did enjoy talking to him.
One thing sticks in my mind is the extra long cage derailleur he had on his bike.
As I recall he told me he'd made it.
The other thing that comes to mind is seeing him mentioned in the Whole Earth Catalog.
I'm not sure if that's a fact but for some reason I have that page image in my head.
Feel free to correct my recollections.
