I was working on my front end today, got one side done. Man, that frame is though as a mothatrucker! I used a grinder and a portable band saw. I didn't know they made portable band saws, my friend passed by when I was working on it and said I should try it, that thing cut the frame like a hot knife through butter. The grinder was a byeotch, but it worked well for smoothing out the edges.
