Cooling pipes with rolled ends?

I'm redoing my water pipes as I have just used straight ally pipe (38mm) and my silicone joints keep migrating down the pipes even with 2 jubilee clips on!
My question is where can I get new pipes made in either ally or stainless with the rolled bumps on the ends to prevent the joints sliding off? Mail order?

I've started to make a bead roller jig in the mean time! I've also found a company called auto silicone hoses that do short bits.

Nice, any more details on the jack roller. The beads look really good, what did you use as formers?

Class effort. Have you any more pictures of the jack as I would love to make one.

Great solution

Ok I have to admit I can't find it at the moment as I'm in the middle of some reorganising. I'll try to find it tomorrow and get some more pics.

It was a standard scissor jack(VS Commodore) which had been damaged. The shafts are from alternators, as are the bearings and the spacers between them. The forming roller is just another spacer which was let spin on the shaft as I ground it to profile(watch you fingers it get hot while you profile it). The ring which holds the former on is from a beetle generator, it has an interference fit on the shaft.
