First, I would like to say I hope this hasn't been posted already, I did a quick search and didn't come up with anything, I hope I'm not stepping on anyone's toes. So here goes.
I was showing my buds son some of my projects the other day, and he really dug my funny car engine, mostly the pully and belt setup on it. So I thought some of you guys might as well.

We will start with a bare blower belt set up

And add a little 1/4 inch aluminum tubbing

Here you can see the pully next to the tube, I feel the kit belt is a little to thin. So I will slice the tube a little thicker and work it from there.

Here you can see the belt surface of the new Pully next to the stock.

A little work with a sanding stick and it's starting to take shape.
Posted Image
Now it's time for the pully bearing and retainer.
Posted Image
Now we need to make one fit inside the other.
A little more work with the sanding stick and it should press in with a little force.

Care Needs to be taken to make sure the bearing is centered as the material is removed around it.
I've also removed some from the back side to sink it into the pully for contest and interest.

Once it's pressed together, a little detail painting and she's ready to be put to work. Two more to go...

I like the looks of black against the aluminum tube, with the hardware picked out with a silver sharpie.

The blower belt was made from black electrical tape cut into a strip, and wrapped about 3 to 4 times around the pully system. I started and ended on the crank shaft to keep the seam hidden as much as possible.
I hope this helps someone out, I've gotten so much info from everyone on this forum, I feel I need to give some back.
Thanks everyone !

That's a good tutorial. I've used different sizes of Evergreen tubing in the past for the same thing. I think I like the aluminum tubing and kit inserts better.
