Thanks, that is helpful and makes a lot of sense because it would match the shape of the guard for the machine . I am dealing with 4-3/4 " drive pulley that someone intended to be powered by a 6" motor pulley with a 1725 rpm motor that was never mounted to the machine. If I did the calculation correctly I came up with that some one was intending to run it at over 2216 rpm witch would be over double the 1200. The problem with the set up someone was intending on using on it is it is probably to fast, and the guard on the machine is only 6" at the bottom witch leaves no room for any clearance for the pully not to rub against it, I am also thinking that it would be better for the motor to have the smaller pully on it and the larger on the machine, unsure if it that matters but it seems it would. I am going to make a 8" drive pully for the machine and will make up a pully for the motor, if I am doing my calculations correctly I came up with 5.56" for 1200 rpm from a 1725rpm motor. If 1200 is the corect speed then all marking on the machine should be in sync with the specs. Thanks for the input, I will do a little more research to double check just in case, the link catalog shows an extra lever on the front of the machine than my machine has. My machine is 13 x 30 M-1395 serial # 230 it is not as exactly as shown in the catalog. Any more info is welcomed !
