Thanks guys.
I actually considered making a few sets, but I just don't have the proper tools to do the job efficiently. In fact the tools I used were; hand drill, angle grinder/cutoff wheel/wire brush, hacksaw, and I used the TIG welder at my school. I'd love to reproduce these but unfourtunatly I can't.
I used this http://www.metalgeek.com/cgi-system/php5.cgi/static/cope.pcgi to make the notches on the tubes. Just plug in the tube sizes, angle then print, cut, tape, draw, notch!
