ok so basically the way this works is mostly all int he gears- I have it geared so that whenever a rubber band is released (only one) the "trigger wheel" (grey beam in the middle of the sideways v) spins only once. so in other words one rubber band=one trigger wheel spin. Then the "trigger" (purple bent beam) is connected to a sort of ratchet mechanism that when I pull the trigger back it makes the ratchet release the trigger wheel which the rubber bands put enough force on to release one. Also I have a rubber band connected to the trigger (the trigger is just connected directly to the "ratchet"or "v" (because it wouldn't fit on the inside of the trigger frame because the two gears that hold the bands are there). soryr this isn't more detailed but if you ahve any questions feel free to ask.
