Where can one buy aluminum ducting that has a small diameter.

The smallest diameter I can find is 3 inches.

Where do you guys get ducting that is the 1.25 inch kind?

I once bought some 2" shop-vac extension hose at Lowes for about $20
Wrapped and wired it around a compact disc. Covered with aluminum tape.
It worked. I think I got the idea from one of Steve Ward's compact designs.

Try the autoparts stores. Ask for heat riser, or heat stove hose. It goes between the air cleaner and a cover over the exhaust manifold. ~70's GM V-8's

Ok, I guess I'll give this a try.

no, it looks like he has some sort of hose covered in aluminum tape. Similar to what I do covering wire loom with tape.
