Pocket Sized Spring Loaded Dart

Step 5: Trigger Assembly

The trigger assembly was originally made out of a copper strap hanger which you can see in the picture. The only picture of the final trigger is an installed on, but the old one shows the concept of how it works. I cut the trigger assembly out of a brass strike plate with a dremel, and then hand filed to the desired shape. Can you tell I like my dremel? The larger hole is 1/4" in diameter, and the smaller hole is 5/32" in diameter. The strike plate already had a curve end which I made the top of the trigger. I pushed it through the chrome sleeve, loaded a dart, locked it in place, and then bent the bottom of the trigger to lock it in place( I beat it with a hammer).
