Thanks for reply....looking to build a "top" quallity one......would just buy one from cold steel but the two peice kind of scares me and Id like the 5 foot model. I just thought someone would know a common used metal pipe or whatever that is the exact size ID as the cold steel 625 models. I have a metal lathe and I think I could make some cool add on's,
I was just thinking I'd have issues with the threads or something not sealing correctly on a two piece. Never dealt with Cold steel customer service either as far as fixing a issue with one. Might be the best idea though....seems like any kind of quality material/tubing cost more than a ready build one. Looking like two options for me...go real cheap or buy a CS commercial one.
I got the 2 piece 5' from amazon for $35 and the 4' professional from Midway USA for the same price. Each place had the other BG for about $10-15 more. Midway has shipping rates that make it less desirable unless you bust $49 so I added accessories and darts to the order.
0.625 is standard 5/8" I.D. tubing but Cold Steel tubing is going to come with a smoother bore than mill run tubing.
I first got a coldsteel 2 piece 5 foot magnum. 625 Blowgun. Was happy at first then started to find things out. The joint in the middle would put an impact energy in to the dart causing a loss in accuracy and distance. A solution had to be found. After quite a bit of looking I found a US company that specializes in carbon fiber tubing. Clearwater Composites LLC. Pick up a 0.625 x 0.741 carbon fiber tube 72 inch long, shipping and all was a bit over $100 and put the cold steel hardware on it. Need to lightly sand some of the cones for a perfect fit, but it's awesome now.
