[Closed] Could I have someone fabricate me an alu front triangle?

Alu often needs heat treatment for structural purposes which is why small scale frame builders eschew it.

Might not be too hard to build an oven out of bricks with an electric element inside and a thermostat.

Carbon instead maybe.. hmm.

Whats wrong with carbon fibre and spoons?

THEY WEREN'T SPOONS!!!!!!

Regards Colin Furze hydoforming, it'll work for non structural parts (if the welds hold) - but a bike frame, I wouldn't trust that as far as I could........

hang on.

Something's gone wrong with the sequence of posts and posters on this thread.

Would any frame builder do this?

They might, but step one is finding a builder who works with Alu.

I've had it done with steel, BTR built me a front end to mate to a Schwinn Lawwill back end, but obviously not all builders will be up for that kind of work, so in a small pool of "builders who would do that kind of thing" you're then looking into the even smaller pool of "and work with Alu".

I can't think of any off the top of my head...

Frank the Welder or Rock Lobster are the only two that I can think of, both in the States though and I've no idea whether they'd take the work on.

What are you budgeting for this OP?

You could ask Orange, they'd do you one with a free swingarm, it might cost as much as a full frame but that's the price you pay for custom. I think they'll limit you to the stock geometry though. 😉

a lot of hydoformed frames are made from standard tube sections that are then cut and profiled to fit together into the individual customers design. Takes out a lot the cost and you get to choose from standard sections with known dimensions and properties for your CAD and FEA.

Vernon Barker used to do Alu, fairly sure the guys that have taken over have continued that.
