Need Help - Looking for some Billet Pulleys

So, I'm looking for some billet pulleys for a non-auto related project I'm working on. While I'm mechanically inclined, I'm not at all a gear head and don't know much about souping up a car or where to find parts inexpensively besides what I can Google search for myself. I figured I'd ping CLSB and see if anyone might have something laying around, might know of a local shop, etc.


The project I'm working on has an electric motor with a 1/2" shaft. I've already spoken to a machinist that says if I bring he pulleys he can try and help me figure out how to get them on a 1/2" shaft.

I need a pulley ratio of 2.6666, so I'm looking at billet alternator pulleys around 2"...which appear to be difficult to find because nobody seems to know what diameter their pulleys for sale are. And I need another pulley around 5.5" to get me the ratio I need. I could go larger on the smaller pulley, but then I have to scale up the other pulley and again, that's where I run into problems. Nobody seems to know what size pulleys they sell.

I'd love to find some nice looking, billet pulleys, and I'm looking for ideas of where I could find some, or a shop smart enough to measure what they have, or even used ones someone might have around.

Ideas?

Edit to add: V-groove or multi-rib, it doesn't matter, as long as I can find a matched pair (obviously) in the approximate ratio I need.

They have to be nice looking. Not necessarily billet.

I already have cast iron ones to prototype the project till I find something nicer...but I don't want to just paint a cast pulley.

Interesting their page never turned up in any of my searches. You'd think with a name like Pulley Boys.

Thanks, I'll look into it.

Check out poly-chain timing belt pulleys with the taper lock bushing. We use them at work for all types of projects. They don't look half bad, not very blingy, but not cast crap. And they work.

I don't have a lathe.

And if I knew someone that did, I'd look into a whole new pulley that looks nicer than machined cast iron.

Can you work a lathe?

You still have that drum you welded up for me/?

No hurry on the drum obviously. I got pissed off trying to tune the first one and had to walk away.

I might have to hit you up on Pulleys then.I'll PM you about it.

your kidding right? redesign the wheel by making pulleys you can buy for 1/10 the price.

unless Jason you work for $3. an hour

Gus
We offer three kinds of service @ Resurrection
GOOD - CHEAP - FAST
You can pick any two
GOOD service CHEAP won't be FAST
GOOD service FAST won't be CHEAP
FAST service CHEAP won't be GOOD
and cold beer.

I'd love to help but I don't chase parts.
Please contact other forum members and supporters for parts.

Gus, I agree. If it's easier to mod existing pulleys then that's what I'll do. The problem is finding nice looking ones in the size I need.

Im not gonna be able to make pulleys from scratch, well i can but it would be time consiming and way more than simply cost prohibitive

gus, all I was thinking about was to chuck up existing pulleys(cast) and just clean off the dull cast surface to make it look better. not reinventing the wheel but dressing it up some, I most certainly dont work for $3 an hour
