French Pin Escapement Mechanism

This piece is derived from a French Pin Escapement Design dating back to 1735 or so...I am still working on it...and will add a second wheel...I am amazed at what a big difference small adjustments in weight, the length of the drive strings, and even the number of teeth/circumference of the gearing has on the speed of rotation as well as the duration of rotation...so much yet to learn!!
