Hey all..  Just got in the latest Northern Tool catalog.  While leafing thru it I spotted this and being new to the whole homebuilding thing I started to wonder how effective this would be for folding flats.

Its much cheaper than all the Jigs I've seen, and doesnt require a press to use..

Thoughts?

IMHO not repeatable enough. Look at the fcg holes and how close they are to the bottom corner. Bend a few mm off and you're done with that flat for good.

RS39 is correct. I'm an aircraft mechanic and have delt with sheetmetal brakes quite a bit. There are actually formulas for figuring out things such as bend radius, set back ect....ect... if you have this info along with the material thickness you could, with practice, bend your own receiver flats. But the price and ease of the better jigs out on the market out weights the problems associated with the brake you have listed above.

+1 on QUIB's comments. By the time you buy that jig, get the extra little pieces & parts that aren't
included, do all of the PITA measurements (with the additional cost for the micrometers that you'd
probably need), you'd be just as well off to buy a dedicated flat bender and be done with it.

That bench top brake will bow and fold before the flat does as it is no where near stiff enough to fold 4130 sheet metal.If you try it the bends will be bowed and very round or radiused instead of sharp 90 degree bends.

I have heard that it can be done with a break and even a cheap break but it would need to be renforced. You also have to remember the mag demples so you would have to modify the break to allow room for these. I think it would be a major pain in the @ss and by the time you cover the cost of everything including the destroyed flats your probably looking at the price of a jig.

I have a jig that I use and I have built 6 receivers with this.  Very repeatable.  I do not know if I would trust this.  You could use to make braces and to make reinforcements where needed.  For example if you are building an underfolder or an RPK.
