Seeking budget ladder chain and sprockets.

[frascati]

Good evening! I'm dreaming up a shish kebab rotisserie. Like six to eight SS skewers (10 to 15usd), 120v 3rpm synchronous motor (3USD free ship from aliexpress.com), some extruded aluminum (couple of bucks from local scrap yard), chain and sprockets.

That last part is the rub. I can find #25 roller chain and sprockets very inexpensively from SurplusCenter. But it's plain (rustable) steel. Roller chain, even #25, is overkill and heavy and going to eat a lot of the limited torque from the little syncro motor in a hurry... especially if it rusts!

It really surprises me that I cannot find reasonably priced lightweight SS wire-loop "ladder" chain and sprockets. Real lightweight stuff like they use in electronics and toasters and RC model drives and such. Even SS bead chain and sprockets would be cool. Still can't find a source.

Any ideas or links? I already got the motors in the mail. Two of them. Constant CW rotation. EASILY powerful enough for this job.

Thanks.

Of course. And thank you for the link. But I did spend some weeks searching before posting here. I included the cost of materials above to give some baseline of expectations for this project. There are half a dozen more suppliers of ladder chain i could cite in addition to sdip-si.

What i was hoping for from the community here was some suggestions more in the spirit of diy. For the cost of suitable chains and sprockets from sdip, et al ( from all ive found so far), even among their cheapest options, i might just as well purchase bespoke rotisseries for a few hundred dollars.
Surely there must be some source of light duty transmission chain/sprockets that would suit such a diy project without incurring the cost of "contact us for a quote" industrial prices? Or am i wrong?

Even bead-chain and sprockets would work for this. But i cant find a decent, reasonably priced, source. Im not being cheap, unnecessarily. But doing it cheaply is a lot of the satisfaction of diy for me. There are dozens of ready-made rotiserrie options on the web.
