Making the dies are cool, but how would you power the sheet metal through it once it's pinched in the vice???

I'd probably make one hole in the vice a plain hole and secure the bolt to the roller with the plain bore, once the rollers are enguged they won't move about adn then you can just use a ratchet or rattle gun.

I've been searching the net for more homemade bead rollers. Tons of others out there too, especially on rat rod and traditional rod sites, but here's one from a Honda site of all places. Looks really well made.

I think the easiest way is to just manually position it as you work the groove around the pipe,
another option would be to drill a couple of holes in the near side roller and use a crank similar in design to the timing belt tensioner
RC no rush mate, steel ones would be cool too...

actually thinking about it, alu one's would be cheaper to ship... and probably do the job quite well, see what you got lying around as stock mate...

Mild steel would be the go for occasional use on aluminium tube. Materials would be half the cost of ally and considerably more durable. Have`nt got any 50 - 65mm bar just lying around, would have to buy it and pay a premium for a short cut length.

These bead rollers often have the rollers designed for <1mm material, as they are commonly used on thin 0.4 or 0.6mm galvanized mild steel sheet for air conditioning duct work. So assuming you`re doing aluminium tubing would ideally want clearance for 1.6 - 2.0mm. I like the profile as shown on that link to the Honda site. Nice construction, workmanship and result.

If you and Mac are serious, come up with a basic design & dimensions and I`ll see if / when I can squeeze it in, but it won`t be soon.

This one on ebay is nearly over. The last one went for $300. Seller is where I bought my lathe, hydraulic press and some other tooling, so can recommend. Perhaps you SEQ boys can get a tool co-op happening?

I have the one from harbor freight but it would be a 2 person job to use it on a tube.

Ok, if you have three hands it could be done easily with one person LOL.
One person can run the crank and guide the material, but it is awkward. I plan to put a motor on it before I use it again. I have a metal lathe so I can make some interesting dies for it. I used it mostly for flanging sheetmetal for patches and for cutting sheetmetal. I have a beverly shear now so it won't see much cutting anymore. I paid less than $70 for it when I bought it years ago.
I suppose with tube you could just roll it as you crank down on the spacing adjustment and not use the crank.
