Lanny Posted December 28, 2017 Share Posted December 28, 2017 25 minutes ago, tvanwho said: Cool, but I always did wonder what pushing the plunger did to make things go Boom? Found this answer for you: When you push down the plunger down, the rack gear on the plunger shaft turns a pinion gear on a magneto (a type of electrical generator) shaft. The current this produces sets off the primer charge, which in turn detonates the dynamite or whatever explosive you happen to be using.

Sourdough Scott Posted December 28, 2017 Author Share Posted December 28, 2017 The pushing down the plunger, turns the magneto with many revolutions. It stores lots of volts. When the plunger bottoms out, it hits a contact plate, which sends out the charge to the detonation cord. Takes lots of volts to charge 20 holes. That could be up to a mile of det cord. 3 1 Link to comment Share on other sites More sharing options...
