Last night during the bearing change on the arbor I broke my wheel pulley.
So, since the pulley on my motor was original and a step pulley I was going to turn around to use for 2 3/4 diameter I figured I might as well replace both.
I tried doing some research on physics and the math of pulleys but that was giving me a headache so I figured maybe someone with more upstairs than me could just tell me?
I was going to use the pulley already on the motor, just turn it around so it would line up making my saw a single speed instead of a four speed. It was going to be 2.75 on the motor and 6 inch on the wheel to give me a 2819 sfpm.
I broke the 6 inch so I’ve been looking at other options. My question is does it matter if say I go with 2 inch on the motor and a 4 inch on the wheel? I know my speed will increase a little but I was wondering if it affected the abilities of the saw power wise?
Is it better to use a bigger wheel on the motor or wheel? Keeping both in ratio to retain the desired speed of the blade of course.
I know it was said that delta used a 2 3/4 and a 6, I am just wondering if there is an advantage to using other sizes since I’m going to replace both. And grizzly has some balanced cast iron in the sizes I was wondering about.
