I've used the delay drilling tool on several motors and it seems to work fine, but I'm trying to figure out the science. Relative to the size of the delay element, the tool makes only a small hole. If the undrilled element has a 14 second delay, shouldn't a hole that reduces the size of the element by almost half be necessary to reduce the delay to 8 seconds? But the tool only makes a hole about 3/16" wide and less then 1/4" deep. How does this small hole cause a 6 second reduction in the delay time?
