beading on intercooler pipes

[BL33SU]

where can i get this done in syd?

or does any1 have DIY to doin it urself or sumthing similar?

[roccodingo]

try any sheet metal shop. Need a sheet metal bead roller.

Are you talking about the weld bead from tig welding the pipe work together?

I think he might be referring to the double flair to keep the hose from popping off. If so I'm interested to hear of backyard methods for doing this too. I haven't see the proper tool but I reckon something could be rigged up out of a set of vice-grips and a roller.

There's always a few on e-bay.

AHHH - i hear DIY mentioned and i'll offer my method (so far proven on 2" pipe to 22psi.... oh, but no-one will have stainless intake pipe but me i'm thinking... hmm, well anyway...

turn your MIG down to a low setting and zap a few knobs around the perifery of the pipe end (about 8 is good). this means no sharp edges and the pipes cant slip off since the hoseclamp would have to actaully stretch to get over the knobbies once tight... make them 1-2mm high is all you need.

That would work fine. When I had access to a lathe I set up a roller from a house sliding door into the tool holder and just wound it against the inside of the pipe until it formed an indent - a bit dodgy but it worked!

I was thinking a set of vice-grips with a roller welded perpendicular to the end of one of the jaws and something welded onto the end of the other jaw to help form the bead and just roll that around the pipe continually winding the vice grips tighter like a pipe cutter.

other thing you can do (aluminium pipe is soft) is whack it over the end of an anvil (if you have access to one) on the mandrel end to flare the pipe a little bit.....

i guess i'm lucky having acess to so much good equipment at work (big hydraulic presses, etc)

Hehe, like me!

You can also use a big steel ball or something similar, sit it in the end and whack it with a hammer to flare the end.

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.)
