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.
Yep the PVC mouthpieces are great. That is what I always use. My conduit BG got bent so I need to make another. Good thing the total cost is only $2I like 1/2 inch electrical conduit because i get a nice 7 footer that doesn't sag.I believe that would be @ .62 cal bore.The mouth piece being a PVC connector. A safety is formed after cutting with a tubing cutter. A little camaflauge duct tape and your ready. Looks awsome and best of all its dirt cheap.
Seamless tubing really is a must.I have made guns from copper, and pvc, with some small bore guns from aluminum arrow shafts with good results, but I have never used the metal electrical conduit due to the seam that runs down the inside, I was afraid this would affect my speed considerably. What do you guys do about the seam, or is it not enough to affect the dart?
