After a bit of hiatus from blowgun shooting, I am going to get back into it... The squirrels are becoming a bit too destructive. With that in mind, I want to build a 6ft breakdown .62 cal blowgun for hunting. I know some would say to pony up and buy a cold steel big bore, but I really don't want to drop the cash on one of those right now. So, I am going to attempt to build a two material shooter of pvc lined electrical conduit. I can do the build relatively easily, except that I cannot figure out a way to seamlessly connect the two pieces. I would think that using a threaded coupling for the conduit would provide a rigid connection to hold the two pieces together, but I would need to couple the pvc as well. Any ideas?
