heath robinson at his best!! Effective though!!
Some bearings for the allen key bit would finish the job off nicely
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

I get it.. I'm guessing a bit of grease helps that one along! looks painful..

you offer the tube you want to put a bead on (eg coolant pipe ally,stainless,copper or mild steel)onto the ground allen key and tighten the adjuster
nut a bit at a time putting pressure on the two wheels that rotate whilst turning
the ratchet 360 degrees until a uniform bead is produced.
cheaper than paying £3 an end or £250 for a manufactured item
quite a simple tool to use
and i,m sure somebody with a lathe could knock one up incorporating bearings which would make it as good as a pro one

I don't disagree at all, sorry if my forst post came over as negative!
I think its a great idea and as you say, given an hour on the lathe i could knock up something comparable with some bushings in it that would be quite
nice (cylindrical grinder even better for doing the allen key!)

Here's some pics I found on the web quite a while ago showing a similar approach to the same problem.

I must say I do like the use of the grinder backing wheels as dies in yours.

Hi Dominic looks ok i used the backing wheels because i had a couple laying about and they are hardened steel
also the allen key is hardened too.
if i had a lathe i'm sure a better more refined tool could be made quite cheaply i'm pretty sure somebody on this forum will use the idea
and come up with a decent example we could all have regards Paul

I used my lathe to do the same thing , I put a bit of bar in the chuck and turned it to shape and then mounted a bit of tufnol in the toolpost with a
groove in it to form the adjustable die, it worked ok on the alloy tube I used .

I was thinking of an even simpler (cruder) design that does not use rollers.
Think of a pair of tongs made from steel plate, 3-5 mm thick, one has the male part of the bead and other the female.
The tube is inserted and the top piece is hammered down, the tube rotated a bit hammered etc until the bead is formed all the way round.
spot the deliberate mistake  the male and female forms are the wrong way round ... but you get the idea.

Hammery thing looks pretty simple.
there was one on the site a while back, someone welded some bits onto mole grip jaws, similar idea to the hammer thing but grip, release, turn,
repeat.

Hi a good site with all sorts of info regarding bead rollers and tube/pipe benders is PRO-TOOLS An
American company but have dealt with them many times and offer a good reliable service.
Cheers Matt
