Russ and I are looking into producing replica Graflex clamps.
I remember years and years ago, there was a thread showing a clamp making press (IIRC). A sheet of metal was laid into the press and a lever was pulled downward, curling the sheet metal around a former, pressing the sheet into a clamp with the word Graflex and the two rows of four lines either side.
I can't remember how the tabs and slot were produced.
Does anyone have any info on this device - or how current replica clamps are produced?
