    I'm imagining the width of the flat after bend is 1.25 + .036x2.
    Snug the bolts that hold the flat and you won't have to hold your breath. Use calipers or anything that will hold your desired measuerment centering your flat equally on your die. I use a peice of wood to tap back and forth till it's centered. I record the measurements so the next time I know where to start. Then as you fully tighten the bolts keep checking and you are ready to bend.

    Measure the placement of the flat carefully to get it centered between the die bar mandrel (slats) and bolt the package together securely. I suggest using a much thicker lead-in die bar to help keep the process oriented squarely while forming.

    Pressing or pounding one end of this sandwich at a time was done to ease the forming process and is rather mickey mouse. It risks creating a misshaped product. Thicker die bars (slats) also help maintain orientation of the work being pressed in the die (angle iron assembly). However... the inner die bar slat(s) must accomodate the indentations already present in the flat or you may damage these indentations.

    These days we have edge-folded flats available which are a great help obtaining a useful frame.

    I just built one of these jigs and grasshopper is just right for the name ,From start to finish 1 hour and 20 minutes . I used 1 1/2 inch angle and made a third bar so the flat would not start cocked . see the pictures ..

    Ps I added roll pins so it will line up every time thats what's in the baggie. I cheated a little i printed the pictures from the forum and used them out in my work shop us old farts have short attention spans.
    lookin good!

I have pressed out a bunch a barrels with it using only a 1/2" drive ratchet and a few pennies. I do put the jaws in my vise to ensure that they don't pop off during the press. But other than that It's almost too easy.

    Here's a couple pics;



    awesome, clever

    For me I kept on looking on line and reading and looking at the pictures. I have the bottom portion of poor mans jigg complete. I used one by one angle iron is 19 and 1/8 inch long. I used four three inch boltz spaced 1 and 1/2 inch apart. 1 and 1/2 inch from the ends. The I used 1/2 by 1/2 bar stock 12 inches long to support the rails on both sides. This was tack welded on, am not a good welder, but it is done. Then I took, shorter pices of the 1 inch by 1 inch angle iron and spot welded it to the ends for more support. These supports are 4 and 3/4 of an inch long tacked to the ends.

    This is what I have so far.

    Someone said those have no heat treatment, and require much more than just drilling, welding in the rails, and completing. Apparently they are too soft and need more than just the fcg heat treatment.

    If anyone has more info it would be appreciated. There is a seller here who has heat treated ones for sale though.
