I was watching Gearz (with stacy davids) on youtube the other night and in one of the quick tips he had a small infomercial about earl's ez-beader, a neat way to put a little bead on the end of tubing...
they only works with a fairly narrow size of tubing and @ $30-75 PER or $400 for the entire kit it's not exactly cheap....
so I did a quick search on the googles and found this... http://www.dsmtuners.com/forums/custom-fabrication/324132-homemade-intercooler-pipe-bead-tool.html
looks about perfect for me... I bought a cheap turbo kit with one of the ebay DSM pipe kits that already have a bead but will have to cut them to make it work for my setup... it's alu so I can't weld a bead onto them with my MIG
just thought I would share... it looks like a good way for cheapo...
