You can find the center by using so tape and dental floss. measure the limbs width half it and mark it top and bottom( put a bit of tape on the limb and mark that with pencil). Tape a lenght of dental floss between the two marks so that it passes over the front of the bow. Put an arrow on the rest so that the tip of the pile is just behind the dental floss and rest the rear of the arrow against the string. You should be able to see how much the point is away from the detal floss. If you have limb bolts with allen key recesses as I have on my compound the whole operation is much easier.
