if you were to put a 10mm piece of pvc into a piece of 15mm it might get some power but not as much as the wood would....... lol

Go with rubber bands.
You can use pulleys to have the string on top while the rubbber bands are tucked underneath the gun.
Use enough of them and you will outdo any crossbow.

That's what I was thinking of doing with the crossbow I made, since one limb is cracked (getting dangerous).

I will probably use surgical tubing or same type thing but they come in thicker sizes for Exercize bands(sometimes cheaper than just the tubing).

I was planning to add a metal plate with holes drilled in it and put bolts through with slightly larger diameter than tubing and slide the tubing over the bolts. They sell rubbery plastic bolt covers too (they're mostly used for playgrounds or protection from the sharp edges of bolts).

I was thinking of bolting bearings through the body and wrapping the tubing around them and running a short string between the tubing.
Beeman sold a slingshot similar a long time ago.
BTW Also there was a dart gun that used them and had a piston inside to compress air to fire the darts.

I may use more than one band on each side. I'll post some pics when I get finished to explain. Wink Cool
