80/20 Extruded Aluminum

[johnohara]

Has anyone here given consideration to using 80/20 extruded aluminum for constructing the cabin or for some aspects of the trailer (cross-members maybe).

This is an example of what I'm talking about:

This stuff is very strong and could reduce the overall weight considerably.

Note: I don't work for them.

Interesting I wounder what would happen if you had to drill through it to bolt down a floor?

We used tons of this at Boeing for making special carts and handling equiptment. For weight it's very strong. With all the specialized fittings, you can build anything

Looks pricey $$$$

I have seriously concidered commercial steel studs for the caboose when I start it. Old what's her name has her heart set on a 3/4 size caboose. It is to be built on my 8x20 flatbed double axle trailer. I think she has figured out that building trailers keeps me home and interfers with my dating.

I looked into this stuff a little last year. It was pricey and I wasn't so sure the clamping system would be up to the task as a frame. If it were more cost effective it would be worth a test though. - Beej

Anyone know how well this stuff takes to bending?

[mikeschn]

It's not designed to be bent. But of course, with the right tools you can bend anything...

I'm not thinking real sharp bends, things with radius generally in the range of feet, 90 degrees with 4' radius and such.

Without some high tech equipment (read 'stretch-forming) the cross section is going to distort

I'm thinking that there are simpler, cheaper, easier ways of doing it
