My father has a pile of machinery here run by a M5? Minneapolis Moline power unit with a 42" Simmonds with the chance to run a 48" Disston. Tried chainsaw milling for valueable logs with a 133 Sachs and a GB mill, yeah, if it don't fit on the back 2 headblocks put it on the woodpile. Kinda makes me scratch my head to see people suffer with a big dollar 088 or 3140 powerheads that won't hold a candle to the Moline. No voodoo, I feel safer around it than a tablesaw.
