If you don’t paint it or anything, you’ll be lucky if it looks that clean down the line.
I’d personally advise against stainless steel. It’s a massive pain to work with and is very heavy. use bigger/thicker aluminum if you’re worried about strength.
So given that mild welded steel from metal supermarkets will look bad since I don’t plan to paint it and stainless steel sucks, will aluminium look better down the line if I don’t do anything to it?
In that case I’m considering this which is close in $ to that welded steel above
Aluminum can be left unpainted and it will be fine. Steel needs to be painted, but honestly you could take the money you save going for steel over aluminum and pay yourself for time and materials to paint it. Just some rattle cans of primer and paint would do it, it doesn’t have to be fancy.
Stainless is expensive and heavy, not worth.
Mild steel is just as heavy as stainless, but much cheaper.
Aluminum is somewhere in the middle price wise, lighter, but not quite as strong. (It would probably be fine though, .095 wall is pretty sturdy.)
Aluminum will not rust, so you don’t need to paint it.
Aluminum is much easier to cut/drill
Aluminum tubes are generally manufactured to much tighter dimensional tolerances than hot rolled steel ones. (they also have a much more square shape)
aluminum is much lighter than steel (~1/2)
so yeah, id probably go with 1/8" wall aluminum tubing (.095 is probably also fine). Im quite confident that will be strong enough, and i think aluminum is definitely the right material for this application.
Hey, I was wondering if I could get some help with a problem I’m having. I just finished the input wizard and setting everything up with vesctool for my DIY build, but only one motor spins up when I give it throttle. Thank you!
Are you aiming to have a metallic finish, and want something easy to weld?
You could sand the steel to give it a even finish, then clear coat to prevent rust.
No speed rating but the 20"high quality alloy wheels with stainless steel spokes with kenda tires seem like standard bike tires you’d have on a kids bike?
