I have a safety pop-off valve but how would you use that as a trigger? It's just a spring loaded valve that pops open when the tank reaches a pre-set PSI. There's no lever or knob on it. ???? The way I'm making the trigger it will be VERY sensitive. Trip wire booby traps have to be VERY sensitive to be effective. I use VERY light fishing line that's almost invisible. Sometimes I can't see it and I know it's there. lol. I also make sure that the instant the land mine has been set-off the trip wire disconnects from the land mine. With a breakable trip wire that disconnects there's no chance of someone tripping and falling. I really appreciate everybody's feedback. This is a great forum. I can't wait to build all kinds of spudiful goodies.grumpy wrote:for tripmines t use a a safety popoff valve as the trigger, with the mine charged to 100 psi it is sensitive enough that only use sewing thread as tripline. i like this as it is easy to get sewing thread in diferent colors so that it blends in better and is harder to be seen.
