cobbled together some metal scrap and this is what came out of it,
one mans junk is another mans treasure…

Essentially you are what we call "Coining" which requires the most amount of force to bend. As a rule (without using the actual formula) bend allowance should be 8x Material Thickness to create a bend with the least amount of force needed and produce the proper bend radius.
As your rig is setup now, it looks to me like you have about a 2" V-die which would be something you would want for bending 1/4" metal, not 1/8" (or 16g). It would be better if you would have set this up as an "Air Bending" press, using up to 30 times less force needed than bottoming or coining as you are doing now.
Also you would be able to achieve proper bend radius's by allowing tool changes of upper and lower dies, as you have now you are limited to basically 3/8" radius bends in all thicknesses of metal you bend.
Otherwise, nice little rig.

good drinks machine ??
Nice ! I like your idea of using hammer drill.
I would use the gas pump, as a air compressor surround.
I have a standup Air compressor, and I'm looking for a pump, but here in Hawaii everything is all rusted out!
Nice work
hi, theres 400+ vids, most of it car/bike builds, thanks for subbin,
hello my name is pmflynn211..great vidio,what other vid,s have you done..i do stuff like this all the time,I just bought a hossfeld pipe bender(non hydraulic)it came with a lot of the dies,but of coase the piece of pipe I have laying around; no dies for that size!!!.it only cost $ 800 …. I thought I did pretty good..just learning how to use it very tricky..again great vidio pmflynn211
That is really sweet. I'm new to sheet metal, and so pardon me if this is a naive and/or an uninformed question, but how do you compensate for the spring back? Your parts look like they are square. Also, I'm guessing that is carbon steel or the like, and since I'm looking to work with AL, would you be able to do a sample of AL sheet?
If you haven't found it yet, try Fastenal
Nice!!
Good idea,better than the others I've seen.
