How about these?
sorry re-design.i did not notice the pics.
mhmm.well i have a jigsaw but i didnts make a rubber band gun.
yesterday i made a gun thats as basic as you can get (almost) first i drew the outline of my gun on a peice of wood it was a small pistol . then i cut it out with a jigsaw. after that i used wood glue and glued on a wooden clothespin at the back and cut a notch at the front of the gun so you put one end of the elastic in the notch and the other end in the clothes pin so when press the clothes pin the elastic shoots out
i said ribber band guns,not spiders.
