Thanks for the response guys. Thanks for the pictures Captain. I think if I can find the pulleys I will use a belt drive system. I would like to find two pulleys that use multiple v belts, if possible. And of course to run the saw at 540 they both have to be the same size. Does anybody know where I can find two matching pulleys? Preferably used and low cost. I have thought of this before, we have two grinder mixers and they both have 22" diameter pulleys that run off of the pto, but one takes a single wide grooved belt and the other takes multiple belts. It is a moot point anyway because I can't use either of those as we still have to grind grain.
The reason I would like to use a belt transfer is to act as a slip clutch, the belts in a multiple belt system are cheaper, and eventually we may convert this mill to run off of a 3 phase motor and it would be a simple matter of getting the right pulley on the motor to get the rpm right. Also the belt system would allow me to run the pto shaft straight.
If we can't come up with the pulleys we will run the saw direct with either a slip clutch or a shear pin somewhere in the system. Thanks.
