beading on intercooler pipes

[gldgti]

oh, but no-one will have stainless intake pipe but me i'm thinking... hmm, well anyway...

I have a lot of stainless pipe work under the hood aswell!

Iscar and Valenite manufacture tooling for internal and external roll forming on lathes. But its easier to simply tig weld a bead around the end of the pipe...

haha - i just thought that most people use aluminium for intake piping... i work all day long with stainless and i love it so thats what i use

For future reference I have finally caved in and bought the Autobahn 88 bead roller off e-bay. I'll let you know how it goes. Done a lot of research plus a few home DIY attempts, but this seems to be about the best bang for buck delivered to Oz. There's cheaper tools, in the US and UK but the shipping is insane.

Roll 4mm wire (eg tent peg) around end of pipe, weld it into place and then grind it back. Mild steel mandrel exhaust bends, fusion weld with oxy acetylene.





Without these lips I initially had problems with intercooler hoses blowing off under boost. Now, now sign of a problem - even with the hose clamps not as tight.

(and an edit: I choose to put the bead at the very end of the pipe but you could equally well put it a little up the pipe.)
