I posted this on the Rotary Performance forum but I figured it would get some interest in here since most here could have probably used this on more than one occasion.
Definately go to this link for more on the story.

pretty nifty!

 

Hmm, has anyone ever just streched an "O" ring over the pipe and vlucanized it together (just easier than welding a bead on thin material)?

That and flaring/knife edging the end slightly where it meets the hose should increase flow.

 

Scalli is da man!

 

Dang Eric did you wander out of the South Forum?
I rolled a bead on a 1 3/4" steel exhaust tube I had laying around to see how it would work. Looks great. The die was not much smaller than the pipe so it will not go down anymore without making the male die smaller.
That would be a waste of energy though since I don't see a need for anything even as small as 1 3/4".
I mainly wanted to see how it would handle steel.
The cool thing is I found out if you use an air ratchet (not an impact ) that it will action in a way that it will walk the dies.
If you tried to use an impact I think it would cause problems like spin out
It's pretty cool though. I set up my foot controller (air valve) and locked the air ratchet to a fixture with the actuator locked on so I could have bold hand free to stabilize the pipe.
I hit the foot switch and let the air ratchet do the work.
Granted that was overkill but.... who says that's a bad thing
I will take some pics of the steel tube and what it looks like in action when the fixture is in the vise.

 

Cool! Looks like it works a bit better than my vice-grip with modded jaws.

 

Brian Cain says it works like an old can opener It is a pretty well fitting description. "Artowar" has a order for one so he can post how he likes it soon.

 

im interested in one. can you email me price? boostedseven@hotmail.com

 

$80 plus shipping

 

a bit much, eh ?

 

cheaper than getting the dies made at a machine shop, then buying the bearing, bolts, etc. and layout drilling/reaming on the square tubes. Then hardening and assembling.
But you can work off the pics and make one and in the end see what you would charge
It's definately the least it is worth to me to make them.
If I setup and made 10 sets back to back it would be different. But I can make motor mounts alot easier

 

good point. im still interested. you take paypal ?

 

yep, I won't be turning out any until the weekend though so they can't go out until Monday That dayjob thingie
FYI, my verified PPal is mikeroberts@charter.net
If you do decide to get one let me know if you want it cold galvanized or painted.

 

That's some crafty ****! I'm going to pass this on to the shop here local.. Maybe They'll get a few.

 

They should only need one unless they have a tendency to lose stuff. It's one of those tools that require a vise so you need to make a place to keep it as close to the vise as possible. Speaker magnets make great holders for things that fall under this category

 

You missed your calling as an inventor...You come up with some neat ideas and cool sh#t.

 

Here is a finished bead roller. I decided to cap the ends of the tubes with plate steel to help keep it from distorting when overtorqued. You can also see that I knurled the drive die and carbon quenched everything except the bearing and bolts so they are very hard now. I don't have a hardness tester but the file test looks really good.
