Small Hossfeld style bender

[H0$$]

Needing to form some 1/8" by 1/2" flat bar to make some letters I decided it was time to toss together a Hossfeld style bender
the bender is nothing more than 4 pieces of 1/4 x 2" flat bar with a few holes drilled in them and some round disks of varying diameters and thicknesses plus some 3/4' bolts for the pins with a length of 3/4" pipe welded in as a handle.

just change the size of the disks to get a different diameter

could you post a drawing, or schematics, or print of sizes used for this build
