So, it is prettymuch non-existant seeming. Since I have exhausted other resources, I will ask here...does anyone know where I can find some 2 3/4" OD, THIN walled tubing (max wall thickness of .125")? Of course some 70mm OD tubing with a max wall of 3mm is fine as well. Mild steel is the material. The other crappy part is that I only need ~8" of tubing...I have a feeling I will end up with a lot of extra. Anyway, thanks everyone!
