My roommate has access to a machine shop but I dont have a jig for bending a flat.
They have a bending break that he could do the bending on. we have access to an arbor press but I dont have a jig. What do we need to know to bend these flats up? |

Not many guys have had much luck useing a brake to bend flats. A nice bend is within a few thousandths. and a brake is hard to keep these tolerances in two bends. there is a lot of info on the various forums on bending flats. Youtube even has a few vids. Good luck and Happy AK Building, Steve
P.S. Here are a few pics of my home made jig. i hope it helps. 
Just turn the nuts and it will suck the flat right in. Dont forget the grease. You will also notice that I didnt weld the angle down. thats because after the initial bend I line the bottom of the bend with the bottom of the jig then put it in the vise and give an extra squeeze to finish the 90deg bend. |

Did you use the 555th plans? Sorry to sound like an idiot, I have very little machining experience. I need exact dimensions so I can have my buddy make this. The 555th jig blueprints have been out there a long time, and a lot of folks have built and used them without any problems. |
