Without a sliproller /ring roller, how can I....
I need to make a 3/8" diameter rod into a ring with diameter from 14 to 16"
I currently do not have access to a slip roller with the ring rollers on the end Does anyone have any suggestions how I can make "1" ring that has some amount of accuracy to being round? Thanks, Steve

I saw on a tv show where they rolled the bar on a spare tire . By rolling the bar and tire on the floor.

I do not understand exactly the task in the translation. Draw a pencil drawing.

I do this often. I cut a piece of stock the correct length ~3.14(diameter+width of stock)~ then I wrap it around something slightly smaller than the target diameter, weld the ends, and then tweak it to a circle drawn on the table. If you're feeling especially clever, cut your bar 8" too long, center punch 4" from each end, then cut off the excess before welding and it will come out very close to round.
I make adjustments to the ring over two parallel round bars about 4" apart. (4" is good up to about 5/8". Thicker material will need wider spacing.) They are welded to a piece of square stock to go in the vise. Put the sharp parts of the circle on the tool and hit with a hammer to straighten it slightly. 3/8" round will move easily, don't hit it too hard. 😉

rings
Depending on precision needed,you can do this with a hammer. Place the rod over a gap in a rigid item, like an open vise, or the step of an anvil. Hit in between the supports and the rod will come around. Toward the end it will be hard to hit inside the ring. I then use a 2" steel rod for a hammer. The vise is a quick and dirty method. To keep it smoother, weld two large pipes together, parallel to each other. The gap in middle works well.

It all works well for me! This is for a locking collar on a tire shaving machine that has a 1.25" Acme thread nut used to hold the wheel assemblies onto the main shaft. I once saw a picture of the large Acme nut with 6 spokes welded to it and then a ring welded to the 6 spokes; the finished assembly was used in place of the "large" open end wrench to loosen / tighten the nut to the shaft after every single adjustment. Thanks for all the help! Steve

Not sure I know exactly what you are trying to do, but maybe and steering wheel off of and older car might work for you. You could drill out the center and weld a nut to the center hub. Measures the wheel diameter on my tractor and it was 15" in diameter.

I've bent a few round things using a circle of chipboard clamped to the bench. The ends of the rod would need to be pre-bent for a circle. A second smaller circle of chipboard can also be clamped by the larger circle to trap the rod to assist with bending.

I used a truck wheel a little smaller than I wanted. Weld a piece of bar across where the beads seat and stick the metal under it. Bolt the wheel to a bench or something solid using the lug bolt holes. Just wrap the bar around center of the wheel.
