I had to scratch my head for a few to put all of the puzzle pieces together on that one but it looks as if it worked quite well. I like how he made a sandwhich out of the flat plates to work around the various dimples and mag well lips. I also like the form he made, I have all of the same pieces cut and waiting for me to weld up at home. Good to see that it is going to work.
555th has success with tapco ak flat!
This was posted on another board and I asked 555th via email if it was okay to post here. Figured you all would want to see this too.
Here is what was posted:
"I built a flat bending jig last night and bent up 3 tapco reciever flats. [edit for item about pictures that didn't pertain to this board]...I basically made the jig to the dimensions of the inside of a reciever, made in 4 pieces so you can get it out of the reciever after the bends are made , bolted a flat piece of metal underneath to hold the mag well and and bent away. for the top rails, I heated them with a torch while it was still in the jig and tapped them over with a hammer and then quinched the in water to get the hardness. I've been thinking of how to make a good jig and I think this one will do great, I'll try to improve it by making the rail bends first with another jig instead of having to use a torch."
"The "block" is in 4 pieces 2 1/4" pieces on the sides and 2 3/8" pieces in the center, which add up to 1.25" . The 1/4" side pieces have cut-out for the dimples and the center 3/8" pieces have cout-out for the magwell lip.. The front of the block is 1.15" and the rear id 1.60" and is 10.25" long. with tabs on the ends to hold them together. bolts go through the center of the 2 3/8" plates to attach the bottom plate under the flat. This keeps the magwell from pulling out during the bend. After the bend just unbolt it and slide the 2 center pieces out and the 2 sides will be able to come off of the dimples. It does a neat job."

justashooter, does look similar, I am part way through bending a receiver now from the jig I got from you. Only difference between yours and 555th's jig is he uses a press. Either way as long as the results are the samejustashooter said:
...Are these jigs going to be for sale? I sure would love to have a jig to bend flats but lack the mechanical skills to build one

I second that request! These would be really nice. You sure could sell a bundle of them. :headspin:
here is an up close pic of one of 555th's successful flat bends.

555th,
I took some pics this morning of the jig I got from justashooter. As for the similarities it is the fact that there is a sandwich of the flat between two pieces and then a three piece center section. This jig doesn't use a press but rather a BFH (big f***in hammer)(I am using a 3 lb hammer) and a t shaped bucking bar. Also your set up bolts differently. The results of a finished receiver from a flat are the same goal (which to me is the main thing). It is interesting how different people come up with totally different yet vaguely similar ideas. Also Justashooter emailed out a pdf file about the jig to those that requested it that helps explain the jig and how to make one. Anyway enough of me rambling here are the pics.

Also here is the original thread from justashooter bending an AK flat that was posted at the falfiles.
