Sheet metal score bending - Angle grinder guide

[Frank S]

I had to cut about ½" off of the width one leg of some angle iron a while back, maybe about 2' worth, and I don't have a bandsaw. I clamped a straightedge to run it along, which sort of worked, but also chewed up my straightedge and my edge didn't end up exactly straight

Its jobs like those when I use my 14" chop saw instead of my plasma or torch still not ideal since heat from the abrasive disk can cause the product to warp. its times like that when I often think about converting to a low RPM cold saw with high volume coolant. I made a vertical attachment for 1 of my band saws which does a fair job just still hard to get a perfect cut. http://www.homemadetools.net/forum/v...8190#post38351
