This time around, I want to see if I could create a crossbow out of a heat formed PVC bow/prod strong enough for hunting medium-size game. I have this 2 inch Sch 40 PVC pipe that's been laying up in my garage (meant for airgun build I never went through with), and I'm thinking of flattening and tapering it into a bow in the same way Nick (Backyard Bowyer) did with a 80-pound build he did several years ago: https://www.youtube.com/watch?v=4nYHUbzApc4.
I'm aiming at a 32 inch nock-to-nock width with a drawlength of 13-14 inches, give or take. To form the prod, I'm going to first flatten the 2" pipe to a thickness of 1-1/4", then form the taper. Like Nick, I'll be cutting out a V-groove at the tips to lighten the limbs and form a secondary taper, and then adding a bit of reflex to hopefully get some more energy efficiency and speed out of it. I'm hoping to get at least 160 fps out of a 600 grain bolt. I reckon this prod should give me at least 150 pounds of draw weight when finished, judging by the 100 pound prod from a 1-1/2 PVC pipe Nick made for his crossbow.
