Try an appliance repair shop (Yellow Pages). If they don't have one they can probably either get one or tell you where to get it.

Any hardware store!

Ace Hardware, NAPA store, almost any small engine shop, MSC, McMaster, Grainger.

You haven't looked very hard, have you?

Thanks Stan

Thanks, When I pull it back off I will have to check the Y-Dimension. Stan

I went to the local electrical supply house and they had nothing. They sent me to an appliance repair shop they said would have everything he he looked at it and had no idea. Thanks Stan

Tried the local electrical supply house and an appliance repair shop neither had any idea where to get one. I did have it in hand for them to look at. Thanks Stan

I can imagine an elex supply not having it, but it's a standard item... I cannot think of a single small engine shop that doesn't have a wall rack of Browning pulleys.

In THIS group, you make one on your lathe.

And if you're really good, you made the lathe, too! ;-)

It is assumed that one has already made one's lathe, from sand castings and barstock, as a condition of membership [sniff]

Extra credit for lineshaft drive

Extra, extra credit if you've built your own nuclear power plant, including the 3 phase alternators and refined the fuel from raw ore. ;-)

Actually, one teenager built a nuclear reactor in his backyard. If I recall correctly, he used the reactor to convert americium to plutonium. It actually worked.

Make that "any *serious* hardware store". :-)

And don't bother specifying that it is for a window fan. That may confuse the sales person if not an old one. :-)

The pulley is specified by the diameter, the diameter of the shaft hole, perhaps a fancy method of locking it to the shaft, and the size (width) of the belt.

And others have already pointed you to McMaster Carr has them, and probably Grainger and MSC as well.

Enjoy, DoN.

What he actually built was a hazardous radioactive site that cost a lot to clean up.
