RE: Does anyone have access to an 04 Diamond owners manual?
I don't remember the exact position of the cam, but I've made quite a few strings for diamond bows and as long as the string and cable are the exact correct length, the cam was always timed correctly. The old Diamonds were very consistant bow to bow, so I never had to adjust the string or cable for timing. I'd recommend twisting the string and cable to get the correct length under tension. It should be fine if you do that.
