BumpMaster?????

[assweasel]

Anyone know where this can be aquired?

Maybe I don't have the name right.

It is a device you use by hand for bumping.
It uses its own blanks (no need for keys) and by pushing the top it not only bumps but also turns the key at just the right time to open the lock.

Supposedly there is a switch for direction of bump and if you open wrong way throw switch push again and it plug spins.

This was gleaned from shop talk. Only problem is the person talking can't remember where he read it and then again wouldn't be the first time he has pulled my leg.

Never heard of such a device. Does it chew your gum for you, too?

Sounds like something out of a tv movie

Timing the application of turning force is a trick I never mastered. If you could consistently apply both the bumping and turning force and adjust them that would be a very cool tool. Unnecessarily high tech, but cool.

I have actually worked out something like this in my mind, but I have not yet been assed to build one. It would include a mallet as well and still fit in your pocket.

The idea is this:

Have a piece of metal tubing, roughly 17mm or a bit more than 1/2 inch in diameter. Basically a bit bigger than the plug itself, ideally the size of the shell, so you can rest the tool without obstructing plug rotation. The key might have to be machined to fit into it. A nice hard striking plate that fits into the cylinder is above that, mounted to a rod that extends to the outside of the tube and ends with a handle. This thing is loaded by a spring. By pulling the handle out (maybe have markings on the rod to be able to measure and adjust striking force) you pressurize the spring, when releasing (release mechanism or just letting go) the striker slams the key inwards. Pretty much like on a pinball machine.

Now, the tricky part is getting the dimensions right, and things get a bit hazy here. Once the striker hits the key and slams it inwards, it would have to strike something else on the bottom of the tube a few milliseconds later that converts the force energy into a rotating motion, it does not have to a long turning motion, a light sidewards tap should do the job. I am not yet sure how to get this done properly. After striking the rotator the striker would come to a hard stop, you are not ramming the key through the lock with a mallet, but give a short tap of energy, not following through if you know what I mean.

The tricky part is adjusting this action properly, it is all within 1 or 1.5 millimeters.

I know this is pretty hazy, but I have no clue on what programs to use to make proper tech drawings (CAD, I know, they are a science in itself), but maybe someone is bored enough to try this

sounds like you wanna hit it with a plug spinner that triggers just as the strike goes in, since there would have to be bump keys for each type of lock, perhaps you should design it to simply screw down onto a bumpkey, like one of those impressioning vises. a trigger could be arrainged to fire it with a rod that strikes the plug face just as the key hits shoulder. for each strike, you would have to rewind the spinner, and given the extra mass of the tool, the bump hammer may also have to be redesigned, could even be contained in the tube, I think this is easily possible, but the forces of the springs would have to be tweaked, after that, it would open a lot of locks and need to be adjusted for some where there is backpressure on the plug

it would be cool to see this exist and work

I like the pinball spring plunger idea. One could easily put markings on the plunger's shaft as a reference to the user so he could increase strike force with each attempt and give consistency to each and every bump.

I think the advanced model should make some 'ping' noises and light up.

Where's Rube Goldberg when you need him?

I have a prototype but dont know of any commercial tools on the market and nor have i heard of any other tools on a simular line outside my own circle of tool makers,

It would be good if you could try and find out where this guy has heard this from,

By shop talk i take it you mean talk in your shop and not a name of a forum somewhere?

I have a couple of prototypes of bump/turn devices that I was playing around with a few months ago. These were bump key based, the problems I found were the variables of spring tension, lubrication, wear, and brand of locks, among other factors, that gave varied results. When I adjusted it to open a lock it was having a problem with, it wouldn't work as well on a lock that it worked fine on before the adjustment.
What I found was that with a properly designed bumphammer, and a little practice, hand, eye develops, and the brain kicks in, and adjusts for variables on the fly. I could not design improvement into this.

i can do some 3D autocad stuff. also i can do fairly well 2D autocad stuff, but 3D looks cooler.

i was surfing the web about an hour ago and watched a video of a guy and his diy automatic bumper. if this is what your talking about he tapped something like a plug spinner. i left for a second to go find it. i dont no where i seen it. it will come to me and i'll post it.

Depending on what kind of browser you are using, you should have a history function that might make finding this thing easier. It's CTRL-H on Firefox for example, maybe the same on IE.

wow it worked but this my take awhile i cant believe all the sites i went to and some of them the browser wont display. but I'm working on it. it mite of been photo bucket.
