|Components of Gang Lun Fa Huo, from 'Wu Bei Zhi (《武備志》)'.|
Gang Lun Fa Huo is a friction-wheel mechanism similar to wheellock, although it is simpler and more primitive, does not utilise any spring, and is way too large to be installed on handheld firearms.
The workings of Gang Lun Fa Huo
Gang Lun Fa Huo is actually a suprisingly simple device. Save for its friction wheels, entire device can be manufactured relatively easily without specialised skill or equipment. Two pictures below, drawn by myself in Adobe Illustrator, show the workings of a Gang Lun Fa Huo in basic configuration. There are actually several different configurations for this device, although all work on the same principle.
