Sheet metal score bending - Angle grinder guide

[skibo]

If you could get a really nice straight cut you could weld the backside or inside where you notched the cut and it would be absolutely strong enough for most needs! I had a 4' sheet metal brake, I didn't use it enough to warrant it and it was always in my way so I sold it. Nice work, not quite sure where the pipe is in your pictures, unless your talking about the square tubing?
