Why on earth are you debating stainless and aluminum? If you need to ask about either you aren't ready to work with either of them. Just built with 4130.

The typical exchange:

First-time builder: Hey, what do you think of using [materials I happen to have lying around]?
Everyone: That's a poor choice and/or more difficult.
First-time builder: I'm sure it will be fine.

Nice work on the compact packaging and making the motion ratio curve a little progressive without a linkage.

Damn, I like this fixture. Most I’ve seen have the bike offset to the side of the fixture, not on top of it like that. Looks clean ????????

I was building my bike as a school project, but this quarter we had to move 100 percent online as a result of Covid-19.

So... order placed from 8020.net! I’m going to assemble the fixture here at home, and then mark all of my cuts and miters with sharpie on the tubes.

Once i’m allowed back at school, hopefully this summer or fall, I’ll jump right into cutting and welding.

Thanks R-M-R, spent quite a bit of time on the layout to make it so.
