How To make a Pipe Beader for Intercooler Piping, bead your intercooler pipes for under 10$!!! Options

[presure2]

So for the past couple years, i've been trying to find a way to bead the ends of intercooler piping.
There are several available beaders that do an excellent job at it, but as little as I would use it, it wouldnt be worth buying one, (they are a couple hundred $$ minimum) so i've been looking around trying to find a good home method.

some guys like to weld a bead on the ends, which i dont like to do, its messy, and not very consistant.
so i kept looking around, and came across this site on the net that showed a guy who had made a beader out of a set of vice grips, an exahsut clamp, and a washer. it looked like it worked, but at the time, i didnt need it, so i didnt make one.
fast forward to now, and i wanted to bead the ends of jims intercooler piping.
i remembered that site, and went to look it up, but its no longer there.
so, i went ahead, and built one from what i remembered.

basicly, you get a set of 10" vice grips (i used a cheapo set from harbor frieght, they were under 4$), an ehxaust clamp for whatever size pipe your beading, (jims is 3", so i got a 3" clamp) and a nice heavy duty washer ( i used one that i had in my "bucket o bolts")

weld it up like this:







you insert it into the pipe, and squeeze it like this:



and you end up with this:





and there you go, bead your pipes for under 10$!!

thats exactly what i did for when i beaded my intercooler piping. I ended up finding that idea from a random nissan forum.

Did you grind down the washer so the edges are more of a circle shape than edged?
