Abstract
A projectile launching device includes self-timing without cam lean. The projectile launching device includes a riser, a rail, two energy storing components, (such as two limbs), two cams, a launch string, and least one cable. The ends of the launch string are attached to the two cams. Opposing ends of first and second cables are coupled to the rail. A mid-portion of the first and second cables are slidably engaged with the first and second cams, respectively. Alternatively, a single cable may replace the first and second cables. The two cams are preferably built as mirror images of each other at a centerline of the rail. The two cams include a launch string track, having identical, but mirrored, upper and lower cable tracks.
