I added a 20 to press to my tool arsenal. Now I'm looking for some homemade metal brake ideas or links.
I bought a cheap 36" HF brake some time ago. I made several modifications on it for the clamping mechanism and extended the "handle." It is only rated at .12 ga or so, but for the money, with the mods, it does fine.
In hindsite, I should have spent $800 more dollars and got a used finger brake. I would have quadrupled the number of times I used the brake if I had a finger brake instead.
There are several videos how to make various brakes, but in reality all of them require dedicating a work bench and a bunch of work to get what you can get out of HF for. (It's $238 advertised)
