*Bump Keys are ON SALE*
Posted 26 September 2006 - 05:15 PM
Having created my key i have set about creating an automated tool for
hitting it with the correct amount of pressure without the use of a
hammer/screwdriver/stiker. But ive yet to have any success.
Ive been playing with the idea of a spring loaded mechanism with a place for
the key to be fitted while pressure can be applied to the correct
rotation direction and the spring takes the place of the striker. Has
anyone perfected such a device ?

cheers mate, thats pretty much exactly what im talking about ! anyone got any thoughts on the best way to make one ? ie- firing mechanism, spring strength, housing etc....
This is the same device as in the video from this website:
Here's a breakdown. It's simple and self-explanatory. It's not the best-looking tool and there is tons of room for improvement, so someone improve it or build a better one and tell us how you made it.
I took a file and filed grooves for tension as you can see in the 4th photo. When I did this the key wanted to slide into the pipe so I took a hammer and beat in the sides a little.
I also clipped the end of the spring to make it easy to change keys.
