Narrow, heavy duty metal brake
I want to bend up some ~12 ga. CRS but
I don't want to buy or house a big brake. I need 6" width maximum. After Googling over the past few days, I have not located a chunky little brake that will do that for me. Can you recommend a tool that will do that please? Thanks! --Winston |

There are two small brakes I can think of that "might" work. One fits in the jaws of a bench vise, and you use the force of the vise to operate the brake. You could probably make one if you have some suitable scraps laying around. http://www.grizzly.com/products/6-Vise-Brake/H3245 The other is called a press brake, and works basically the same way except you operate it with a hydraulic press. http://www.northerntool.com/shop/too...ct_21896_21896 Unless you made one with multiple blades neither would work well as a box brake. |

I'll bet that'd hold against 12ga steel. For just an 8" (6" capacity), you could add a lip to mount it in a vise. Unless you need super precision, one of these would work tits. -- Not merely an absence of noise, Real Silence begins when a reasonable being withdraws from the noise in order to find peace and order in his inner sanctuary. -- Peter Minard |

Hoever for something with 4-5" jaw width and 6+ opening it would be too heavy for those little steppers. The least little bind or one dry spot ont he ways and everything would probably go to hack. I routinely do pieces 4 by 6 on the mini mills. Its my standard size for one type of project I do. I keep being torn between a vacuum clamp and a vise. Right now I have a stop block t bolted to the table and squared, and a piece of angle with a shim. When I titghten the bolts through the angle it tilts on the shim and clamps the work piece. The t-nuts are the most expensive part of that "vise." Its all made out of aluminum and its pretty forgiving. Tool crashs go right through it and it still holds like its supposed to. Its also a pretty flexible application. Every piece hits the table squared the same. One day I should put a side stop on the bar so its positioned the same also, but then I couldn't wider plates. I was thinking with a titanium vise I could machine shallow grip parrallels into the jaws, and machine positioning stops in for different width plates. That way I could have a lot more working room and would never risk a tool crash into my clamping hardware. |
