CA-AB Sched 40 Aluminium Pipe

[DPittman]

I"m looking for some 4" ID schedule 40 aluminum pipe. I see Metals R US has some and it will be about $100 per foot delivered to me.

I need 8"-12" inches and will be cutting it half longitudinally . I need to make a mounting "saddle" that fits over another tube and need the thicker wall because I want to have it welded on.

I don't know if you checked here yet but this is the first place I go when I need small stuff.

No i haven't yet. Thanks I will check online.

Do you just need the one half? Perhaps you could just bump bend some 1/4" flat plate into the saddle radius required seeing as how it's welded anyway?

This is for a tail wheel modification to my ultralight plane. Similar modifications have used plate and bent a couple of curves into them but that seems to be a weak spot on them that can eventually crack. The "saddle" it self will be riveted onto the body tube and I plan on getting a heavy aluminum channel welded to the half pipe saddle. It is the aluminum channel which will then have a steel leaf spring bolted to it.

What are you welding it with that you need it to be 1/4? , .100 - .125 is easily welded, and would likely be much cheaper and easier to source

The channel i have is probably a good .25" wall. I figured if I kept the two pieces similarly sized the welding might be easier? I dont have aluminum welding capabilities so I have to find a shop to do it anyhow.

Ah ok, thanks for more context.

Ya sorry I should have right from the start. I sometimes think its too hard to explain well enough thru text so I omit the details and that is seldom the right thing to do.

This is how some have done what I am trying to do but with the half pipe way.

All good, it's impossible to describe every detail for everything sometimes.
