I've been wanting to make a silent pellet trap for some time now and I finally got around to doing it. My design was inspired by the full size AGE silent pellet trap that is sold commercially, except I wanted something smaller. Most of the targets I shoot are just drawn on flash cards, and propped against my backstop with a rock or two. Its frustrating when its windy, which it is most of the time, having the flash cards blow out of position in the middle of a group so I needed to make something that would hold them securely. A clip on top would still leave the flash card vulnerable to the wind, so I decided to cut notches in some 2x4's to hold the flashcards in place. I did that with a table saw, and after the notch was drilled in one long piece of 2x4, I cut it down to size to properly fit a card. Then I screwed it all together, and added the top block for stability and asthetics. I'm going to buy some plumbers puddy for the backstop, and put that in behind where the cards go as well as a piece of plywood or something to hold it all in place.
I'll post pics tomorrow when its finished.
