Arrow Bending Corner Guards

I am looking at making some of the corner guards like the ones below. My question is, how would you come about making the bend around the rear corner. I was thinking about bolting it on the back and then heating and bending as see fit. Just wondering if anyone has any other ideas. It will be 3/16" thick steel. TIA!

I don't know what kind of pricing you get on material but I went the Barbedwireoffroad.com route(whiskeyv8 on ebay). $157 to the door for corner blanks pre bent.

go get 2 pieces of pipe that are a few inches longer then the piece you want to bend, with a radius that matches the radius you want to bend it at, weld a piece of heavy flat stock between each end of the 2 pipes so that they are parallel and about 1/2-3/4 inch apart....you will then need to make some sort of a stand to hold it, which could just be made out of some scraps (I would make the stand so that the piece you are bending is getting pushed down)...you could also weld a piece of flat stock to one of the pipes so you can clamp the material and keep it straight, but thats not entirely necassary...insert material, heat, and bend

if that doenst make any sense, I cna draw a quick pic of what I'm talking about

trying to heat and bend 3/16 around your sheetmetal will just cause alot of damage to what you are trying to protect

yota bill's jig idea is how I would do it too. You would mess your corners up for sure. The heat and metal scuffing it up can't be good

You won't be able to bend 3/16" steel without alot of heat or without a press. You could probably get away bending 1/8" though.

With that much material (24" or so?) you would need the whole bend cherry to bend it by hand. We looked into getting the tooling to bend 1/4's in our press and it's $$$

3/16 material x 24" in length will take approximately 90 tons (180,000 pounds) to bend without heating. Yield strenghts stay pretty constant up till around 1100 degrees F.

So, good luck.

Thanks guys for killing all of my dreams, haha.

Whiterhino - how about 18" of 1/8" is that still pretty impossible?

The chart for our press says .188 is 7.5 tons per foot with a 2" bottom die, 14 tons per foot with a 1" bottom die.

Still more than your going to do by hand.

Well I have a possible work around if your good with a welder and a grinder... Buy some tubing the that was the same radius as the corner you are trying to protect. Then cut it in quaters length wise. Use these quaters as your corners and weld your flat each side. Grind down the welds and your done. A lot of work but it could work.

I was thinking that too, but a 6-8" tube could be expensive. It's kinda janky too!

If you do a really good job lining everything up, and finishing your seems no one would ever know lol. True big tubing like that would be pricey, you would have to weigh it against the cost of buying pre-built ones.

www.speedymetals.com for the tube

and why waste your time when such an affordable product like the one from barbed wire offroad exists?

I contacted barbed wire and they said they took them off their online store due to not being able to have free shipping any more. I'm waiting to get a quote from them to see the new shipping/product rates.
