Mechanical Bumping Device With Video

but the weight could probably be reduced with plastic.

Good luck and please share the final results. After I built this thing and it worked I thought it might be possible to build it out of PVC pipe, but I never attempted it.

this is actually a really cool tool... hah.... it looks simple aswell i like the way you could use most bump-keys with it(if not all) loving the idea.. i think i'll try something similar ...

Jimb,
I have been working on idea of combining a circular tension wrench with your bumper. I think if I am able to spring load the tension wrench, it would eliminate the chance of applying too much torque to the Key, and will provide steady torque to the key. I am thinking about making a web page to track the progress of this. Please let me know if you have any suggestions other then what has been posted in this string so far.

If you can get a very light spring for tension then it might work on most, maybe all locks that can be bumped. It's difficult for me to bump most locks with a constant tension. On most locks it requires me to catch the pins at the shear line. If I remember correctly someone here has stated they can bump any lock with constant tension?

I don't own a circular tension wrench, would it interfere with the bump key in the keyway, or will the key slide in with the wrench?

Jimb,
The circular tension wrench would be attached to the bumper as another exterior cylinder, so you apply rotation and are able to pull back on the plunger. The key would attach to the interior cylinder, so the tension "tube" would not interfere with the keyway or key. I do not have an exact design in mind, just ideas at this point, but I will be getting some stuff down on paper in the near future. Once I do I will put the progress page up and post a link to it, so you can give me any input that you like.

my computer wont let me do flashplayer! man i want to see this clip, the machine looks real cool,. Anybody know where i can find another format? bleh.

disregard, used firefox instead of internet explorer. NIICE machine, i'm going to make one tomarrow, it seems like you could alter it to twist after impact. but hey, who am i to say? awesome thread!

I have mounted my bumpkeys on my electric pick gun in an 90 Degre angle to vibrate/bump the lock both on the way in to the cylinder and out of it making it realy intresting. i still have some fine tuning to do. Adjusting spring tension and vibration amplitude to optimal.

Some pictures i toock yesterday:
Enjoy!

I like it. Have you opened anything with it?

I have been planning to build something similar and had not considered using the electric pick to do it. I may have to rethink my idea now as I was going to buy a cordless filet knife and try to make rakes and bump keys for it.

Great idea, and that's a cool leopard print bump key!

Great idea, if you can a Video of it in action would be nice!

Hey the Pics are gone, did anyone download them? If you did could you PM me so I can take a look?

Thanks,

Don't know if its been mentioned, i'm not going through 6 pages right now.

But i was thinking, you could use something like weighing scales (often used for weighing fish that you caught)

Like this:

It would be much easier for people who don't have the machining skills or machines to build the more elaborate bumping tool featured in this thread.

Just a thought

Genious!

I don't know if anyone had the photo's to send you but the bumpkey was attached at a 90 degree angle. It was a clever idea.

By the way, an interesting thing I've found with pin in pin cylinders is that it's possible to hit the key on the side and not straight on the key.
