I was bored so I made a chinese repeating crossbow from leftover crap wood from my school. The stock is recycled from my old bamboo skewer chinese repeating crossbow and the bow is made from laminated bamboo. The magazine can hold up to 12 bolts but I'm currently shooting 7 bolts. It may be crude but it works just fine. The effective range is pretty short cause the bolts have no fletching in order to fit into the crossbow magazine. I guess that's why the chinese coated the tips with poison.
