I might have to try that...I'll see if I cant run up to Home Depot tomorrow
I think I will give this a try in the near future, it would make a smooth yet strong gun.you might try sticking 1/2 inch pvc (.84 od)into 1 in steel electrical conduit (1 in id) thats pretty close...closest I can get at home depot...might have to wrap the pvc in tape or something
the point is not to have any joins in the pipe....even the slightest change in the smoothness of the inside of the pipe slows down the dart velocity. with the 3/4 pvc there is no creases or lips inside the tube....you can also choose the length of support you wantrather than using a bigger dia. piece of PVC pipe and working a way to support the PVC-BG... I took a straight connector piece that was made for that dia. ( they sell them to connect two pipes together)...
now a 6 foot piece of the stuff costs somewhere around 20-30$.Macklinburg-Dunkin sells six foot pieces of what they call 3/4" Aluminum Bright tubing for about $12 in many hardware stores. It is about a 64 caliber, lightweight and wont rust. Check it for bends and dings before purchase. Also available in four foot lengths.
