I needed to have a Rebar bender for this project and just made one. Funny, I used an old Ford FEL section. Good solid hing point. Soundguy would likely recognize it! First I made a mandrel with the correct raduis. Also, I made a grove so the Rebar would tract nicely. Then, using the old Ford FEL part I welded the set of leverage points, the triangles, on to the lever arms.
Works good with 1/2" rebar. I would have tried 5/8" but Lowes did not have it
