So I decided to build a ring roller to make MY OWN rings. I have it completed and now I just need to fine tune it. The two bottom rollers are driven together. When I put the metal in and put pressure on it , then turn the handle the rollers just slip on the metal and will not feed. The rollers are very smooth.The only thing I can think of doing is to have the rollers knurled, to help feed the metal. dose any body have any other suggestions.
any help would be great.Attachment 2823
Hi bullchuck. That's a nice roller. Is the pressure enough? Try adding some rubber/abrasive tape on the rollers, or texture the rollers.

You could also add some rosin to the surfaces of your rollers to give them more grip. There will be a small area of pressure that will allow the roller to work. Smaller rings would take several adjustments to get done.
Nicely done .

Thanks bullchuck! I've added your Ring Roller to our Ring Rollers category, as well as to your builder page: bullchuck's Homemade Tools. Your receipt:

Thanks for the reply's. I have plenty of pressure on the metal, there is a 3 ton jack pushing down. I am going down to a machine shop tomorrow, to see what it would cost to have the rollers knurled. I had to take the day off today being so nice and take the quad out for a ride.
Another thing I thought of, do you think the bottom rollers are to far apart?
If you want to see more pic just ask. Thanks. Mark
Hi bullchuck,
I work in a shop that uses that type of equipment all the time, what thickness of material are you trying to coil? and is it round or flat? We mostly work with machines that spring form rings with material diameter or 0.027" to .140" but the theory is the same no matter the size, generally the rollers that move the material are prior to the forming port and pull the material through a set of straighteners. Also, we groove the rollers to match the diameter of the material.
Hope that helps,

I am mainly trying to roll 1/4" & 3/8" round rod. What I am trying to do is roll a 20' length at once, and have all the rings the same size. I saw this on the web , and that is what I want to achive.
Ok so I had the rollers kurled today and the metal still slips. I am tThinking the bottom rollers need to be closer. ??????:headscratch:
The rollers should probably have groves put in them to allow more surface area to contact the material. You may need additional drive rollers to move that size material though
I'm not building a roller anytime soon, but that's a good insight.Quote:
