So with permission I took his idea and ran with it. Drew it up in CAD, and chopped it out on my CNC plasma. I made it from 1/2 inch, and 1/4 inch steel. The results were not too great. I discovered the error in my ways. My slots were not wide enough, and tore, and my holes were not spaced correct. The two holes next to one another were over 1 inch apart, and I wanted them to be 1/2. (oops messed up on that calculation) Once its done and correct, Ill repost pics. It will be a great beginning welding project for people, and there will be NO cutting, a bit of alignment, and several different joints to weld up. (2 corners, 2 fillets, 2 plugs, and 2 round fillets) the bar stock I'm using is 7/8 solid bar, but the kit will have 7/8 tube. (to keep weight down) I'll be looking at $30 shipped if anyone is interested. (as several guys said they were) being that they are built out of 1/2 inch steel, the bender should be capable of bending up near that. And will probably require a nice long cheater bar.......................... But it should be able to do it.Keep in mind, that this was a test and the metal is rusty and not prepped. I did not see a point in prepping steel that was headed to scrap. Now without too much more typing are the pics of the failures.

Reply:You might want to burn a few more holes in the pieces. I'd look at the HF knock off bender and make up pieces like that instead. The builders could use pipe or sockets as their dies ( make the holes 1/2" instead of the usual 5/8" and they can use 1/2" sockets.) You don't have to do the ring, but it helps to do repetitive identical items.All they really need is the 2 plates for the stand and the 2 plates for the fork. The ring could be optional. Most of the other parts could be made up from square tube or even pipe and help save on shipping costs.If you want to get really slick, cut out the triangles with holes in them to make the square corner die. ( If you need picts, I can take some for you of mine this weekend.) Or burn out some plates with center holes that could be welded in standard size pipe diameters for larger dies.

Reply:NBDF, Help my ignorance, how did you cut the slots? Looks great also.
Reply:plasma cutter.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:Yeah with plasma. Makes for great ways to bend up brackets that need matching sides, for bolt holes/pins because the cut parts srs attached to one another. Makes for an easy bend without a pressbrake, you just weld up the slot after the bend.Offering CNC Plasma cutting and welding projects.Follow me on facebook https://www.facebook.com/nobigdeal.fabSupport those that support WW.
Reply:Roger, thanks.
Reply:Originally Posted by NoBigDeal FabI'll gladly make one for guys looking for more versatility. I can build pins that will allow it to be adjustable. I'll also see about making a degree wheel with common marks on it at say 22.5, 45, 90, 180 ect. But it would only be close and not dead accurate. As my machine can only hold about a .05 of tolerance. But it would be consistent. This would raise the cost (and defetes the purpose of a really cheap bender) but if it will sell it's no problem.
Reply:Shoot me a pm, with shipping info, and I'll get one out to you. (was trying to finish up a bumper today) but if you need it now I'll put a bit of a priority on it and have it done tomorrow. Shipped on Friday, and if you pay shipping you can have it as soon as saterday. ( or any other type of expidited shipping) Or later next week, if I send it USPS.There really is not much left to work out. And it will be good to go.

Reply:Looks like you need a little more radius on that bend in the first pic   just joshing...who would have a bender to make their bender?That is why all super big equipment is welded!Good to see a local AZ member,
Reply:I'm in too... when you figure out all the extra that DSW mentioned post pics and price. You figure to use PayPal?DannyMy SiteJust worrying 'bout what I can't get to today.
Reply:Yeah I will accept paypal. Once I get this design done, I'll look at DSW's to make it more versital.My question is how big does a bender need to bend? Is 3inches wide enough? At some point the job has to exceed the tool. Where another tool makes more sence. I'm thinking 3in wide is plenty. But if there is a large need for 3.5-4 it would be easy to accommodate.Offering CNC Plasma cutting and welding projects.Follow me on facebook https://www.facebook.com/nobigdeal.fabSupport those that support WW.

Reply:Ok I should have a final design done this evening. (I'll be at he day job fir another 2hours) then I'll get right on it. I'm hopping to have 3-4 ready to go tonight. As I dont have much 1/2 inch left, and gotta pick some up on Friday. but I have plenty of 1/4 and 1/8 I could have 20+ in that thickness ready to ship in the morning.

Reply:A what-if question.I might try to make one myself, and like the idea of using 1/2" for the part that clamps in a vise with the rest being 1/4" stock.  I don't have the horsepower to cut or weld 1/2" material, so would it be feasable to take two equal pieces of 1/4" plate, slap them together with an edge weld all the way around (with an inside bevel on the edges) to make a 1/2" thick piece?  The two 1/4" pieces wouldn't move and would probably give enough strength to resist bending.Originally Posted by shortfuseA what-if question.I might try to make one myself, and like the idea of using 1/2" for the part that clamps in a vise with the rest being 1/4" stock.  I don't have the horsepower to cut or weld 1/2" material, so would it be feasable to take two equal pieces of 1/4" plate, slap them together with an edge weld all the way around (with an inside bevel on the edges) to make a 1/2" thick piece?  The two 1/4" pieces wouldn't move and would probably give enough strength to resist bending.
Reply:OK, thanks for the advice on sticking with 1/4".
Reply:OK its been a really long day. I started trying to get the slots to cut correctly so that the material would not tear. I was not able to find a solution to that problem. So I decided to attempt a Tongue and Groove idea. That failed as well. (its really close and I may look into it a bit more) I then decided lets quit trying so hard at being lazy, and just cut it out in pieces. So I did and came up with a final result that I am happy with. I have 2 sets ready to go, and can have them out tomorrow. There is alot more steel here than I originally thought though and gotta ask $45 for it. I'll stick to $30 for one done out of 1/4 and 1/8th though. The only thing different from my pic VS the actual kit, is that I have 7/8 .188 wall DOM included for the round stock instead of solid. The kit can be had without the center hole to put the handle though as well. (please let me know when ordering) Without further delay here are the pics.

Reply:like the dovetail design...
Reply:yeah i gotta play with it some. because cutting it with 1/4 inch notches its just not quite accurate enough. to get the detail needed. but im thinking if i step it down to about .20 it may just work.Offering CNC Plasma cutting and welding projects.Follow me on facebook https://www.facebook.com/nobigdeal.fabSupport those that support WW.
Reply:I think you're hurting yourself going with the dove tail. You're making the welding WAY More complicated then it needs to be. Just cut the pieces out and let us weld them. It's fare easier for you, and actually less work for us as well. I think you're better off aiming for that $30 price point. If that means sticking with 1/4" for the clamped piece so be it. Like you said, you should be able to do larger stock with some heat. which you'd need to heat anyway even with the 1/2" clamping section.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:yeah i agree. the dove tail was a bit overkill. it was something i thought of and figured why not. it was about 20 min of time. i agree on the 1/2 inch as well. buying 1/2 is not cheap. i picked up 3 feet of 7in X 1/2 today and it was close to $70. that takes a huge chunk out of the $30 price point. VS going 1/4. also I need to reconsider the handle being DOM is not the best idea at almost $5 a foot. its way too overbuilt, and ill gladly sell it that way, but I think you are correct. I really think that even going with 1/8 main body and 1/4 for the piece that clamps in the vise will be plenty. and if i go with 1/8 i can make it bend up. as i have done a bunch of stuff that way with 1/8.Offering CNC Plasma cutting and welding projects.Follow me on facebook https://www.facebook.com/nobigdeal.fabSupport those that support WW.
Reply:I think that you're pushing it dropping the swing arm down to 1/8".There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:Maybe. Once I fill the orders I have, and get a bit of breathing room I'll build one and see. It's really the only way to find out.Offering CNC Plasma cutting and welding projects.Follow me on facebook https://www.facebook.com/nobigdeal.fabSupport those that support WW.
Reply:might work ok on thinner stuff; but then the holes for the pins may need to be spaced different.
Reply:Yeah pin spacing needs to change. I'll be spacing them at 1/4 inch to make the max capacity on a thinner metal less to avoid the possible damage. I'll have some pics up later tonight of a bend from different versions. I have a project to finish then I'll be on it.Offering CNC Plasma cutting and welding projects.Follow me on facebook https://www.facebook.com/nobigdeal.fabSupport those that support WW.
Reply:Ok I have final pics of the heavy duty benders. They are made from 1/4 inch stock, 7/8 pins and 1/2 inch stock, for the larger radius. The smaller radius is made with 1/4 inch stock 7/8 pin and a 1/2 pin. enjoy the pics. and feel free to make suggestions for improvements or PM about getting your own.EDIT: Please prep your steel. I did not, and should have. But these were the first built, and were for testing and I considered them one time use.

Reply:It's hard to tell in the pics. But is that 1/4 you bent?

Reply:Thanks. Two more.1. Do you think it's better to have the holes offset?2. How long did you make your handel?I first copied this to be able to make my own staps to hold a 16 gallon gas tank for the pic i use as my avaitar. Its a frame i'm building for a 70 El Camino street car; Blown 468 BBC, lots of spare power. And i may use 1/4 straps. I need all the weight i can get in the rear for traction. Thanks.
Reply:I like the offset, it allows the handle to be at an angle from the stock being bent. But I don't know it matters much. My handle is 16 inches long but the flat stock is also 7 inches long, so it's about 20 inches from the bend to the end if the handle.Off topic, but do you know a guy that races a black 4door 4x4 dodge ram?

Reply:On the dovetail, instead of 3 why not just do 1 small one in the center.

Reply:yea, ixnea on the dovetails.Re: the "rollpins" though, extend the one in the handle and secure it by welding washers on the ends so it can rotate.  This will relieve alot of friction and actually make bending easier.Lincoln SA 200Esab Caddy 160Thermal Arc 201TSMiller Dialarc HFI don't like making plans for the day because then the word "premeditated" gets thrown around the courtroom....
Reply:The pins are fixed, and I like the idea of making it roll. I'll look at it as it's really a simple modification.

Reply:Originally Posted by burnt09About the offset pins. On my second bender, which was sized to handle 2" wide stock, I did not offset the pins, and I can now bend a full 180 degrees. Not sure now  why I offset them in the first place.
