Before i say anything about this crossbow, you should know that a 50lb crossbow is dangerous. Anyone that wishes to make one should realize the dangers associated with it. Do some research before even thinking about this project. I dont want any injuries resulting from this particular project. So BE WARNED! Now that that is out of the way, let me explain. This is a 50lb draw crossbow that I made in about 2 days of light work. It requires very little supplies and is relatively simple to fabricate. I'm not going to dissassemble it to explain, for reasons of being too lazy, but if I get enough feedback MAYBE I will.
