One of my more favorite tools for tubing and flat stock is my horizontal band saw. I believe it is a 10" capacity? I can set it and walk away to do other fabbing. Where a cutoff wheel must be manned the whole time. When I need exact production / reproduction work, that is the go to saw. I also have my hydraulic clamp, 14" cold saw which, once set up, doubles my production. The cold saw also does angle work easier than the band saw. For weird shaped stuff, the vertical band saw. And for stuff that doesn't fit in the vertical band saw, the plasma with various guides. The plasma can make very accurate and straight cuts when set up properly.
