There I had a little help. Originally I had planned on using 2- 3' pieces of the 2" X 2" X 1/4" angles and a 2' piece of 6" channel, but when buying the metal from a local steelyard I found that they only sell in 20' lengths. I bought the angle (approx. $35) but decided to check our (college where I work) scrap bin. I instead used a box that was a project made by students in GTAW class. The box is 24" X 5" X 3" deep out of 1/4" steel. I donated the 8' of angle I had left over to the college.I have the set of paddles to do this but haven't settled on a base yet. More details on yours would be helpful.
