Ring roller anyone made one ?.
HI ALL, Just wondering if anyone has evermade a Ring Roller. I have the Plans for Rortys Design. I am thinking of making one more like on this Website http://www.shopoutfitters.com/ . When You check out their site have a look at their Universal Bender -not bad hey. Does anyone have any Plans for a Ring Roller like Theirs ?.
All the best Stewart (steran50)

Hi
I built one based on the shop outfitters design, I wasn’t able to find good enough reference to reverse engineer it off of there site but was able to find some good photos of a knock off one on ebay. I never drafted anything up but I can post a couple of photos now and if you like, post some more later with some measurements. It was pretty easy to make if you have a lathe and could be made without one with a little ingenuity. It works super on solid, round and flat steel and its good for square tube to about an inch. I have since added power feed and a digital read out as it can get pretty tiring rolling, and as I found out very small increments of roller height adjustment equal large changes in radius.

Ring roller
HI 12 teethperinch(Darrell),
Wow I am impressed that is great work. Thanks for posting the Pictures. Some Measurements would be great when you have the Time. I see You have used split collars on Your Rollers so they are easily adjusted to different material. Instead of having a lot of different Rollers, what a great idea. To give Me something to work on now can you tell Me the Following Please ?.
1. What size are the Rollers ?.
2. What size are the Roller Axles ?.
3. What size is the Frame material (flatbar) ?.
4. What is the Hydraulic Jacks Capacity ?.
Keep up the great work.
All the best for Xmas and the New Year.

Hi Stewart
The rollers in mine are 3 inch diameter by 3 1/8" wide they were made from some super hard metal i found in a scrap bin They have roller bearings with 5/8 inch bore pressed in, and the shafts or pins are made from 1/2 inch drive socket extensions which are high carbon and chromed and just a hair under 5/8" in diameter ( lucky eh)
I know the shafts are overkill but I was afraid anything less may bend and then i would have a very difficult time disassembling the roller to fix the problem.
The flat bar I used was 3/8" x 4" I am pretty sure the shop outfitter one is 1/4" or less but I wanted a robust machine and since mine is a little wider then theres it was the right choice, you could even go to 1/2 inch but would gain little in my opinion unless you were scaling up the design. initially I used an old 3 ton jack and it seemed to work fine but it lost pressure during use and I replaced it with a expensive Japanese 5 ton jack. I did this for 2 reasons the expensive jack would work on its side and I thought that tipping the machine on its side would be advantages from time to time (haven't needed to yet) and it had a narrower footprint then the cheap ones and that made it so it could be centered in the unit and and wouldn't cause it to rack. I will post some more photos and give some dimensions soon.

Just read my own post and I should add the center or drive roller runs on a 1" shaft in pillow blocks. The roller material I used was allready bored out larger then 1" and really hard to machine even with carbide, so I turned down 1" keyed, weld on sprocket hubs to fit the roller. You will need to have a keyed shaft or pin the shaft to the drive roller to keep it from spining on the shaft. The best thing about this design is it is simple to make one of the drawbacks though is there is only a single drive roller which can case slipping problems. They knurled the drive roller on the shop outfitters one but my rollers are already hard so I just roughed it up a bit with a carbide bur in a die grinder. It worked ok but I can still get a bit of slipping when i push the limits of the machine.

Great U-built!
Great project Darrell! I've been goin to build on of these for a while now so I will have to keep an eye on this thread for the dimensions
Remember if the ID exceeds the OD the hole will be on the outside!
