Need some ideas on bending metal???

How many do you have to do?

Here is the hand cranked HF version.

So how small can you make a circle with that?

I need about 8 of them right now and if it goes well, it could turn into a monthly thing.

3/8ths round bar is not much more than wire. if you take a couple of pieces of wood, cut them to app 7 1/2 in dia. attach to table, put stop in place to slide rod into, cut to 3 feet or use full length, wrap steel around wood. travel past starting point; the pieces can be tacked to hold the eight, then cut. cut to size. half inch reduction in dia. (ball park) is for spring back. you can use pipe, sheaves whatever. i would try to do it cold no heat.

8 inch diameter rings can probably be ordered.

I originally thought about cutting a piece of plywood to the size I need then cut one over sized to screw to it and then mount it on the welding table to hold in place. I just would like something a little easier and more permanent that is capable of bending many sizes without a lot of work to change around.

I never thought about buying the rings... Might be a st effective way to do it... Thanks

Buying is always the easy way. Iron fence places often have a large selection of steel rings.

You can make circles with an ID just slightly larger than the OD of the drive roll. With a groove, you can make rings that can't be removed from the roll without springing them open a little. If you do a lot, you can add a motor and a foot switch. No idea of the quality or lack thereof on the HF unit, but I'm sure you can check it out in person to see. A lot depends on the finished quality of the rings you are making, as to the best way to do them.

I checked Ebay for rings... I'll check some iron fence places, thanks!

Using the slip roll, could you keep feeding it until the coils wrap around the rollers eight times then cut them apart and weld the ends ?
