Has anyone done any testing with different types of tubing? Is metal, PVC, or something else the best?
I can see that PVC could be a problem due to sag. I also saw that you cab buy fiberglass impregnated tubing. I imagine that it would be stiff enough. I also see that DragonPlate makes Carbon Fiber tubes in .40" and .54" ID too. That would be nice and light... and strong!I have only done metal. Aluminium, Copper, and electrical conduit (not sure what that is, steel maybe?). PVC seems like it would be really fast but you couldnt get the length you need due to sagging. Unless you braced it somehow... or somebody knows something I dont.
