mechanical lock bumping

[padlocks]

Saw this on youtube http://youtube.com/watch?v=8q4AVLjZwF8&feature=related
Thought it looked a very useful gadget, much better than a bump hammer by the looks of it. Has anyone tried one or know how to make it or where to buy one?
It says in the comments below the video more details can be found here, but having searched I can't find anything. Can anyone show me the link?
Thanks

the handle looks heavy, the key must be held in a light grip so that it will transmit the strike.
Never saw that one before, I assume the key is cut back a bit at the shoulder,
With bumping, the strike is very important, it can be too heavy, I tried to bump locks using a large spoon as a bump hammer and it spalled the keybow, but it seldom opened the lock,
The lock in the photo is most likely one he has practiced on quite a bit. everyone who has made a tool will have locks that he is very familiar with opening. However locks respond differently in different locks. different brands, the age and lubrication and the quirks of installation may affect the bumping.
Perhaps this thing is good in most situations, I for got to look and see who that guy is, he may have other vids.

He does have other vids First off the thing is heavy. It does work but not as good as my screwdriver handle. The idea behind this was for 3 main reasons.

1. To show that a mechanical device could be made.
2. To challenge some one to improve on the idea.
3. To find something that looked more proffessional than beating a key in a lock for the locksmiths that occasionaly bump locks.

raimundo, the key is cut back to use the minimual movement method. This is also a lock that is "practiced on quite a bit" that is easy to bump and pick. I have another video of this lock on youtube with me spp, raking, bumping and removing the pins in like 40 some seconds.

padlocks, the thread you are looking for can be found here:

There is another thread on here somewhere that points out an ebay seller who was building and selling this on ebay. It didn't bother me that he did this but he used my video to do it. Using my video without asking did bother me and several people here complained to ebay and the auction was removed.

Thanks Jimb great idea simply executed. Am looking round for the bits to have a go my self. (don't know why i couldn't find it through the search function, but there you go)

I had thoughts about using a pull/push electromagnet, possibly combined with a triggered torque motor, but it's one of those ideas that's a complete waste of time to try. But it was nice to see this clip, much simpler idea and aparently working.

[raimundo]

lucky may have an idea there, but it seem that by the time you start using solenoids or whatever, you might as well just have an electropick, the only difference being how the pins are struck.

however the concept of triggered torque is not yet added to the electro pick so thats a new one lucky, I have looked at some concepts for a mechanical triggered torque, but since I use found items, its all about finding something I can use, so its just another of those idas that are around but unlikely to go anywhere with me until some inspiration strikes.
such as seeing some part and thinking "that could be used differently"

Where? Link? More details would be appreciated.

It's similar in idea to Patent 1,639,919 (filed in 1926), although the arrangement of the spring-plunger is slightly different -- and obviously adapted to accept a wider variety of keys. Still... a very neat tool construction!
