Boost pipe bead roller ideas

I know many home made bead rollers but 2 of the cheap & pretty simple ones that do give good results especially on ally pipe are pictured below.

The famous vise grip & exhaust clamp & washer welded on >

this can do some quite decent beads on ally if radius edge of clamp and thick washer nicely. light smear of grease on outer side of pipe tends reduce tool marking.
If mod it bit more you could weld a flat thick plate with 2 threaded holes to vise grip then have the exhaust bracket bolt on with 2 short socket screws so can change between say 2" 2.5" 3" and 3.5" brackets .

washers to make your bead dies >

seen some done similar with thick flat plate & tubing using bolts with washers, i'm going do one assembly built off a old drill press vice clamp rather than working off bench vise jaws.
Work well and can use a socket and t-bar or ratchet as handle so super cheap & easy fabricate, more so if build off vise using jaw plate mounting holes. if got a lathe turning some dies creates a pretty pro bead roller on this simple design.

Burrows done a cool ball bearing one for smaller pipes (fuel hard-lines) if look in his build topic, similar idea to earls eazy beaders.

I use the vice grip and exhaust clamp, it does do the job when needed.

2nd one looks interesting

Pretty cool idea ... seems relativley easy to make up aswell

Yeh pretty simple and cheap, can use vise grip without welding and mount exhaust clamp in vise by ends and washer over nose of pliers so no welding but modded and welded they produce neater beads and bit quicker use.
Second one done well is as good as most £100+ pipe bead rollers on ally pipe. seen few based around that idea in small back alley garage and custom shops here.

First one is a really simple idea, I haven't seen that before. I used a similar design to second that my mate fabricated up, worked really well.
