I just acquired a Prontor mechanical shutter timer and am in need of some technical assistance. The device activates the plunger to a depth of 7/8 of an inch before the timer activites. However, all of my modern shutters require a plunger to travel a fraction of this distance to trip the cocked shutter. Without the convergence of these variables, this device is useless.
Is there a way to adjust the length of the plunger or is the remedy some sort of surgery to cut it to a lesser length to make it functional?
Thanks in advance.
