ok lol for the shits and giggles try this.
you're seated at a workbench. in front of you are a corded power drill, a very large button - from a shirt ^.^, and a piece of wood approx. 1 ft long a half in. wide and with a bend at one end forming an L, with the short leg approx. 1 1nch.
point the drill forward, away from you. now turn it at a quarter turn to point to your right. the button has two holes spaced equally apart on it's edges. the button is large enough the you can slide one of those holes over the bit of the drill. when you pull the trigger of the drill it rotates the button. now into the other hole of the button insert the small leg of the wooden piece,face the long leg away from you.
now if you should pull the trigger the long leg of the wooden piece will move forward and back.
can you see it? ok think of the wheels on an old locomotive. see that strut connecting the wheels to one another? that's the basic idea.
strip the motor out of the drill and you could probably make a decent machine. we used this basic method to make tattoo guns when we were kids ^.^
ok for my own peace of mind don't try any of that unless you're qualified to do so. people get hurt messing with the insides of power tools. and that's not a real plan, it's just an illustration of a theory.![]()
