Simplest ring roller for flat, round, or square tubing
Today I was looking on an amateur machinists website/forum, and seen what I believe to be the simplest device I have ever seen for rolling a radius into flatbar, and round or square tubing. This is so neat, and the only limit to what you roll is your imagination. As seen in the picture, two rollers are attached to one jaw of a vice, and a single roller with crank arm are attached to the other jaw of the vice. You open the vice, put whatever you need to roll between the rollers, close the vice untill some pressure is felt, then turn the crank and run the peice through, back and forth, untill there is no more resistance, then tighten up the vice and repeat. I suppose that in theory, you could roll a complete circle if you wanted to, similar to the device that Eastwood makes. Yes, you would have to have a lathe to make the rollers, but this is so simple and cheap that I wanted to post it for all to see.---The vice shown is unlike any vice I have ever seen either---looks more like a hand powered bending brake for sharp corners in flat stock----I suppose with an old vice and some ingenuity, you could convert it the same way.---Brian
