Worked on smoothing off mill scale and flattening all surfaces of 3 x 3 x.25 angle for 8 foot sheet metal brake. Used a combination of tools and sanders to try to flatten surfaces. I will be using a design similar to one found on-line however the steel I bought appears to be significantly rougher than that used in the on-line example. Ugg, this is going to take a lot of work again!!
