Ring Roller Plans

[Arbo]

I know several of you have been patiently waiting for the drawings for the ring roller. Well, the drawings came up missing (Maybe Thor ate them? ). I took some close up shots of it, and here they are. I found when designing this one, It isn't the size of the rings that determine what you can do, but how they are spaced. The bottom two are 4.5" on center, and the third falles on the center-line of the other two. If you have questions, feel free to fire away. I will help any way I can. I hope that you find it useful.

Thanks a million. I think I can figure it out with these excellent photos. However, how does the yellow T-handle work? How do you raise and lower the center upper roller in order to determine your diameter? Or do you? I really appreciate your help in this matter.

Thats great looking, what size is the couplings?

What did you use for bearings between the rollers and the risers?

I assume that the pin is for removal of the center roller, after the roll is completed?

How long of a crank handle did you make?

Sorry for so many ?

Thanks Bernie

The yellow t-handle is simply a socket with a handle welded to it. The down pressure on the center roller is applied with a one inch bolt that threads thru a nut that is welded to the upper bracket. There is then a plate that sits above the center roller, and you tighten the bolt down against that to apply pressure. The more pressure, the smaller the diameter of your ring. You want to try to keep your work centered on the rings, so the brackets on the upper roller do not twist.

There really is no bearings, it is just a 1/2" hole drilled thru a total of 3/4" plate that the axles ride on. The two bottom rollers spin freely on the axle, and the top roller is secured to the axle with a total of four set screws (two each side) They are 2" pipe couplings mated with 2"x1/8" bushing reducers. The threads are drilled out of the bushings to accept the 1/2" axle. The handle, if I remember correctly, is 18" and is also on with set screws. However, it slips on the axle sometimes, I think I will secure that with weld also. You are correct that the pin in the back is to remove the upper roll when your ring is complete. I couldn't come up with a feasible plan to avoid this, and still keep this project inexpensive. You can use your imagination and scrap pile for most of this project. I have less than twenty dollars, and my time into it. Hope this helps, have some fun with it!

Ring Roller

Arbo , what sizes of material have you tried with it so far? It looks heavy duty. Flats ,round, or anything else? Thanks for taking the time with all the pics !!! Several people are looking at these rollers. David

I have rolled 3/16X2 flat bar with little difficulty. The rolls tend to slip a little, but if you help the feed along with your other hand, it works nicely. I think that if you were to knurl the upper roll, it would help it to grip some. I tried doing some 1/2" round HRS, and that was more than it could handle. It did put a bend in it, but it wasn't pretty.

I don't think I would knurl the roller, as this will mark the workpiece under pressure. Consider a large diameter heat shrink tubing, available from any electrical supply shop. When applied carefully, it will go on pretty even, and act as a tire. You can even get it with a heat-activated epoxy inside, so it cannot slip on the roller.

Arbo,
Very cool roller! Did ya use regular old tubing or pipe for the rollers? Are the bottom rollers on there permanently? You might try making a big steering wheel thing to use for a handle. I think if ya had a bigger handle then it would be easier to use thicker stuff. What, no hydraulic jack?

It appears to me you guys are trying to reinvent the old tire roller for wooden wagon wheels.
