I finally managed to finish a functioning crossbow, kind of. It needs alot of refining, especially as the trigger pull seems to be around the 40lb mark. But it fired a 18in bolt a good 35 feet and hit the target only a few inches below where I was aiming. I made it out of several bits of ply wood in pretty good condition, a piece of slightly beaten 2x3, and some old tongue and groove, all of which Irescued from a fire pit at work. Also all the screws and bolts I had lying around, so it cost next to nothing to make, in fact pretty much the only things I bought were a piece of rubber from ebay, a length of metal tube for the rollers and to make some slip on arrow heads and a couple of cable tidying clip things to make a quiver. Probably no more than £10 for the lot. And the design obvious borrows alot from Joerg's bullpup crossbow, hope you dont mind, it just seemed to fit with the materials I had available. I am toying with the idea of carving a slogan in the side of it saying "Born 2 Kill" with the 'O' swapped for the peace sign, kind of as a homage to the film Full Metal Jacket. The torch has only temporarily been fitted as a bit of a joke with my brother in law, who will probably be getting this as a birthday present. Its a bit of a work in progress still, but I'm loving how its turning out, and its really comfortable, especially with the hole in the fore grip.
