I'm sure there's been plenty of these in the past but I thought I would share my ideas for a quicky ring roller. I've been putting off making a ring roller for a long time now. I've always wanted to make one along these lines.http://www.ercolina-usa.com/angle-ring-roll.htm I wanted all wheels to be powered (that gets complicated in a hurry) and possibly even make it a 4 wheel with two main pinch rollers and two bending rollers on each side (I've got a brochure that shows one of those from years ago). I just never had the time to start the project much less complete it. Well this week I had two jobs needing completion that really needed a roller. I've gotten by in the past with all the old tricks. Wrapping around a piece of pipe with C-clamps and the like. But I was tired of it and decided we should throw together a simple one. It looked like we'd have time the next day so at the end of the day on Monday I had them start cutting stock and start on the rollers. Of course things didn't go as planned and this week turned into a bunch of late nighters just to get the work out. But in little breaks here and there we managed to get most of the parts built. I went out into the shop this morning with the plan of finishing it. Of course that didn't work out with two big emergency jobs coming in. Me and my main helper worked till 6:30 just getting those out. But I decided to stay in the shop and at least get some of the assembly done. Well it went better than planned so I managed to just about finish it tonight. I still need to make a handle to drive it with and take care of a few more details but I did manage to roll a ring with it. The ring in the pics is 1/8" x 4" strap rolled to about a 12 1/2" ring (one of the rings I'll need for the upcoming projects). I just threw this design together in a couple of minutes with soap stone on the table. I don't know where I came up with all the ideas but I know I've seen several of them before in other rollers. My main criteria was quick build, wide enough to roll a 4" wide strap minimum, relatively small and light weight for storage, and versatility for later upgrades. The design did get modified a couple of times throughout the week. I was originally just going to use some of the 3/4"x1"x1" super oil light bushings I have (I have a lot of these left over from a project). I still used them in the bottom rollers but the top got upgraded to 15/16" shaft when I had a friend give me the flange bearings. I wanted it to be easy to open the top for removal of the finished ring. This posed problems and caused another design change after getting the bearings. To keep the same side plates I turned them over and added the hinge/pin connections for the flange bearings. I want to keep the ability to make special rollers for things like tubes and the like. I made sure the top shaft is a slip fit in the bearings and the bottom rollers just drop in place. The rollers that are on there now are about 2 3/4" dia. We can later make others and the ability to change the placement of the bottom rollers allows for more versatility. Oh and for those interested I welded it up with 5/32" 7018 and 175 amps. I just felt like using stick for this project and I'm low in 1/8" 7018.

Reply:I like that flip open design. On mine I have this wrestling match thing I have to go through to pull the top roller part way out.

Reply:nice work and simple. i have needed one for a while. i think ill build one like yoursthanks for sharing godbless
Reply:Super cool! That is the simplest design I have seen. It clearly meets your requirements. (Mine too ). Small, rugged, easy to store, easy to pull out and set up, easy to use.No doubt many copies will be made!-MondoMember, AWSLincoln ProMIG 140Lincoln AC TombstoneCraftsman Lathe 12 x 24 c1935Atlas MFC Horizontal MillCraftsman Commercial Lathe 12 x 36 c1970- - - I'll just keep on keepin' on.
Reply:Perhaps you would enlighten the ignorant: How do you start the material? It doesn't look like you just feed it; looks more like you place it on thebottom rollers with a sacrficial leader to bridge the gap, then clamp down on the top roller to position and then install the pin. That starting clamp action looks like it might be a bear.Or am I missing part of the actions? Rufus
Reply:Nice work irish. I think I have all the materials to actually build one of those things. Might even add a groove in the rollers for rolling round bar.MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!

Reply:There was a request for info on what I wanted to change on the ring roller. I'm pretty sure I wanted to change the spacing on the bottom rollers but I don't remember to what. However I did do a quick modification to it recently when I needed to use it to roll a bunch of large rings the same size. The jack wasn't working well for this since it was hard to repeat with and it started leaking down during a roll. I looked around for one of the screw jacks like comes with most pickups but couldn't find one (I think they might make a good replacement for the bottle jack). So I just put in a piece of 1/2" grade 70 threaded rod and a piece of pipe. The only problem here is that it takes a while to do a major move since you can only get one flat at a time with a wrench. I also had some problems with the sides springing which would allow the bottom carrier to tilt sideways so I added a piece of strap between them.

Reply:Do you have any regrets going with just the one driven roller?My name's not Jim....
Reply:So far so good on one drive roller. I've wanted to build a ring roller for a long time but I always wanted to drive at least two if not all three wheels. This caused me to put it off for a long time. However I'm not finding it much of a limitation with just one drive roller. It might make it easier to get a piece started without backing off so much if they where all driven however I'm not sure of that. One thing that may be working in my favor is the fact that I put good bushings in the idler rollers and the drive roller is softer metal which tends to get rough on the surface (that was a accident but it works). I still need to get a some pieces of strap tacked to the sides of the carrier to keep the pins from the idler rollers from sliding out. That and a better clamping mechanism are the main regrets. Powering it in the future would be nice but not likely. It's pretty rare for me to need to roll something. Now this last batch of large rings would of made power real nice but then that's what I've got a helper for. :-)Millermatic 252XMT 304'sDynasty 280DXHypertherm PowerMax 1250Miller Trailblazer 302 EFIOptima PulserXR feeder and XR Edge gun and more athttp://members.dslextreme.com/users/waynecook/index.htm

Reply:One thing I found works when making full circles for handwheels and such is to roll two half circles, actually more than half of a circle, that are the same diameter. When doing a partial circle it is easier to keep the bend in one plane and you just play with the second one until the diameter matches the first. Draw a circle the diameter of the bent tubes and lay one over the other over the circle and mark both at 180* for the cuts. When cut you can make 2 welds instead of one and you get a circle that is very close to being in the same plane. The handwheel below is 1" 16 ga tubing and isabout 13" in diameter. It only has about 1/16" runout vertically and horizontally. Cut an MGB and widened 11" C4 Corvette suspension and LT1 Chevrolet power & 6 spd.

Reply:I have a question for you (2 actually). How do you attach the upper wheel to the shaft so it will drive? To change upper wheels do you just slide the shaft out or do you have to remove one of the bearings? I like your design much better than mine.Cut an MGB and widened 11" C4 Corvette suspension and LT1 Chevrolet power & 6 spd.

Reply:irishYou could use a scissor jack there good for about 2 tons push with very slow movement.I had to put flats on my lower roller shafts to stop them from turning with heavy pressure.For those who want to make their own roller speedy metals has steel tube in many diameters and wall thickness.

Reply:The bottom carrier has a guide and it rides in a slot and has a retainer to keep it there. Attached Images
Reply:Ok. I knew it had to have a guide just couldn't see what you used. Nice and simple which is good on a project like this. :-)Millermatic 252XMT 304'sDynasty 280DXHypertherm PowerMax 1250Miller Trailblazer 302 EFIOptima PulserXR feeder and XR Edge gun and more athttp://members.dslextreme.com/users/waynecook/index.htm
