Saw Mandrels Built From Car Rear Ends
FARM SHOW readers might be interested in saw mandrels I built from the rear ends out of cars. They let you drive a sawblade off the pto of a tractor instead of a belt pulley, thus eliminating annoying belt slippage.
I built the mandrels mostly out of the rear ends of old Ford cars with a 3:1 drive ratio. I ran a driveshaft off the axle end of the differential to the pto and attached the sawblade shaft to the driveshaft. I mounted the mandrels on two-wheel trailers and shielded the blades, of course.
Most of the mandrels I've built were used on 24 or 32-in. dia. sawblades and the 540-rpm pto on the rear of the tractors were ideal for turning blades at 1,500 rpm's.
I used to sell the units for $300. (Mark Foldesi, Rt. 1, Box 369, Greenbush, Minn. 56726; ph 218 782-2619).
