needed a bigger bender to bend some steel on my truck,bender i built is 5ft wide, basically found some 1/4 inch by 2 1/2 inch angle iron laying around the shop, went to the local hardware store and bought a hd piano hinge, drilled holes in angle one and 3 in the diagram, used steel pop rivets and riveted the hinge to angle 1 and 3, angle no 2 rounded off the edge drilled and installed bolts through the end of angle 2 and 1, welded 2 square stubs at the end of agle 1,took 2 pieces of steel tubing,drilled a hole into it, welded a nut to the tube ,installed a bolt, this then fits over the stubs i previously welded (makes unit more compact)welded a piece of tubing at angle three to install a handle and basically your done! if you have to bend smaller metal instead of uning the clamp down bolts i use a c-clamp,i basically made this as easy as possible and cheap because time is something i don`t have! hope this helps somebody in the future! Darn can`t get diagram to download, will try later!
