Does anyone know how to make a rope c**ker for a crossbow I have nylon rope and some equipment I just don't see a point in paying 25$ for one of you could make one.

maybe this could help. http://www.ehow.com/how_8019610_make...-crossbow.html

Seriously man? How much did you spend on a xbow or how much is an ethical shot worth to you. Just don't see how $25 would influence your decision to purchase a cocking rope when the price of everything else is much higher and the difference of just a 1/4" in the cocking of your string at 20 yds means it will shoot 4" off. Not to mention the safety factor involved for your own personal well being. Anyhow good luck to you and be safe.

What do you mean by this statement? Are you referring to being centered on the pull?

Yes. If you are off 1/4" of center on the pull while cocking a Xbow it results in 4" off at 20yds, 8" off at 40yd and a ft off at 60yds.
