Ideas to Repair Ring Roller Jackscrew

[Shootr]

Ok, I've never used one of these machines obviously, but when you are rolling square stock, does it sit flat on the rollers? Or does it sit up on edge in the grooves? Is it possible to use it either way?

On this particular one, the roller grooves were specifically made for 1/2" flat bar or square tube. Either material fits into the grooves. The "drive roller" has a raised ridge in the center of the groove-it collapses the inside wall of the bending tube, I guess so the other three sides remain smooth.

I have so far rolled both of those, as well as 1/2" copper pipe, 1/2" EMT conduit - both of which worked well, but neither remained round, the profile shape was kind of acorn or arabesque shaped (pleasing, but not round).

I also rolled a 1-1/4" wide flat bar just this week for the first time. It just rode above the grooves, remained dead flat, and smoothly rolled into a nice hoop.

I have an original manual Y2k roller. It uses vee roller and will roll heavier wall round stock (greater than 11g) reasonable round. Noticeably greater distortion on 14g and thinner.

On your bender, I would be hesitant to go too thick on round tubing, since you might distort the edges of the die?

Even the minimal distortion is noticeable when butting rolled parts together or combining straight to rolled parts.

Appreciate the heads up on the possible roller damage. The EMT was for the ships wheel I made to replace the original crank handle. The copper was a test for an idea I saw on the internet.

I'll lay off conduit but I think the copper will probably be OK once in a while.

Interesting... thanks for the response.

Copper work hardens so as you pass it through the roller, it will get progressively harder. Use a propane torch to heat the copper up and it will return to a softer and malleable form.

To aneal copper torch it then quench.

Does the square tubing also work harden as it is rolled?

[psacustomcreations]

I am pretty sure the square tube is just A36 mild steel. That does not work harden as far as I know.

Sometimes the cheapest mods can be the handiest - put a brodie knob on my ring roller - man does that speed things up!

Get the Harbor Freight pipe threader and then make an adapter for the ring roller. Now it is power driven. I bought the roller adapter from Swag Off Road for the Harbor Freight tubing roller. Then I made a adapter so the pipe threader fit my sheet metal slip roller.

Good idea Shootr. I put them on our forklifts. We call them “suicide knobs” around here.
