Re: Swingarm brace aluminum extrusion
09 May 2021 22:16Yes, I thought i would be able to find it too. I know a guy that has a company that specialises in aerospace components, i'm going to ask him before I try and make it myself.I see. You want that outside detail. I would have thought that would be possible to find, but poking around the web it does look like it's a bit of a needle in a haystack. Everything seems to be either plain square extrusions, 80/20 type functional shapes, or weird window trim. It may be the case that someone somewhere has some stock of that, but I think you're right that it would probably take less time to machine plain square tubing yourself.
I can't help you with alloy choice, other than to say that 6061 does not bend well in a sheet metal brake. The notes on the extrusions in the McMaster catalog say that 6063 and 6060 are both "easier to form than multipurpose 6061".
Good luck.
I like the way the brace looks with the detail....

The early GSXRs used a tube profile like that. I don't know if it would be cheaper to cut up a frame to get the tube but its an option. sub-frame tubes are 20 x 25, main down tubes are 27 x 30. this is a proprietary alloy similar to 7005.

Probably doesn't have the look your after, but what about Chrome Molly tubing?
That is what was used on my swingarm to brace it:

Funny you should say that, I actually have a 1988 GSXR1100J Frame {last of the slabby's}, I won't be cutting it up though, they are starting to fetch good money....
