I sharpened the 12” OD cutter wheel to a 60 degree edge, 3/16” wall and inside edge only.
Then chunked up about 100 gallons of wood.
This was a it tougher wood, maple and 3” diameter is about the limit and that is cutting at a 30 degree angle.
I stalled it a few times but the large push button stop switch allows shutoff in about 1 second.
My retirement stopped on 2-05-2018 when my current airport project at Paine Field in Everett, WA started up again.
Working 10 hr 6 days does not allow much DOW time
