« Part 1: Cleaned up and trying to decide if I should keep it. Part 2 of Delta Unisaw series Part 3: Not so lucky with the age of the saw »

I took the pulley off of the motor tonight and success!!!

I tried the nickel test and I would just like to say that the nickel test is worthless. My nickel stood up even before I took the pulley off and you could see the saw vibrating.

Now the same test with a dime is very accurate. I could stand a dime on end and start, run, and shut off the saw without it falling over. That is impressive.

The Ridgid ran with the nickel easy enough, but the dime would fall over when starting or stopping.

So, my motor is OK, I just need to get a new pulley for it. I went to the Sunflower Woodworkers Guild tonight and am now a member. These gathers of the minds are great for a beginner like me. I was told by a couple people that the cast iron pulleys that came with the saw are junk and that I should get a turned steel pulley.

What do you all suggest for pulleys? What about belts for the Unisaw. Should I get a new match set or should I use Link Belts? Do they make a Link Belt for this saw and if so, does it require a special pulley?

Thank you for all of the great advice.

So I was right about the pully! Well you get lucky sometimes.

That’s good news. A pully is cheap!

Link belts would be best as far as vibration goes. I think that it’s a standard 1/2 belt wich is a
direct replacement so it uses the same pully. Get a turned one.

One source for the linked belt and pulleys is In-Line industries. They have these available as kits. The linked belt will definitely reduce the saw’s vibration.
