Bumping 'n spinning

[vector40]

No, not a dance...

Suppose you bump in the wrong direction. Might be able to remove the bump key if the pins are all short enough, but maybe not. If it's stuck in there, and you want to spin the plug back, how would you do it?

I guess you could find a way to spin the bump-key itself when it is in the lock.

I can't remove the bump-key from locks normaly except my 000 key I made myself... but if you could make the bumpkey turn the lock at the right speed it should work.

That's a really good question. I'd think it wouldn't be too hard to mock up a tool for this using the good ol' mouse trap spring. I see a spring, a small bulldog clip and some dowel. Might be worth making something like this. Maybe there's a better way though, so before I go running down to the work bench I think I'll wait to see where this thread goes.

I'm wondering if simply attaching (in whatever way) a plug spinner blade to the bow would work... seems like you'd need an especially strong spinner to overcome the additional mass. The better ones could probably do it (I have the feeling the Dyno can spin your laundry dry) but I dunno about the rest.

You might be onto something.

Probably putting a bolt through the hole and stretching an elastic band over and letting go of the bow may work.

Isn't a bump key cut to 999 anyways? What would stop you from removing the key? It's not like a high low combo would block it.

[digital_blue]

Well, if there was a 9 cut in there (or maybe an 8?) you would still get caught on the ramps.

Like Shrub said, putting a bolt through the bow hole, but instead of a rubber band, position the key as close as you can to the inserting position without re-setting the pins and slap the bolt with your finger/hand/whatever as hard as you can. I reckon it would clear the chambers without re-setting.

[digital_blue]

I dunno Chrispy. I've tried doing this with a tension wrench and I've never had any luck with it. Seems it'd be a pretty dodgy way to go about it.

if you could make a clamp mechanism able to grip the key, attached to a spring of sorts to spin, or a proper plug-spinner it I really don't see why it wouldn't work.

[Exodus5000]

Yeah, the only way I can picture spinning a bumped lock in the other direction is to put a tension wrench through the bow, and do the old rubber band trick...
unles you have the bump key ground down enough to fit the blade of a plug spinner in there?

[TOWCH]

Not worth the effort, but picture a 2 part bump key: The ramps on one part, and then the rest. Then lock them together real well to use. To remove the key: Seperate them, pull out the bottom half, and then remove the ramps.

[digital_blue]

Well, I'm still holding on to my bulldog clip on a spring idea. So far, I think it's the most likely to work. Granted, I suppose the rarity that this situation might come up probably makes it less than worthwhile to build it. At the end of the day, it's not so much the fact that you'd have to make the tool, it's that you'd have to carry it for the "once in a blue moon" time that it would be needed. Probably easier to just bump in the right direction to begin with.

I'm not so sure. If you seriously use bumping as part of your toolkit, and you ever deal with ornery locks (remember that it's not a great idea to bump a lock for ever and ever, since real damage does occur), I could certainly see turning the wrong way and wanting to go back. No different from any other opening; you just don't want to do it twice!

[workstation]

I have seen a video of someone bumping one of those multi-point locks where you have to turn the key repeatedly. To overcome resetting, they simply turned the key to just before the setting point, then hit the edge of the bow with a hammer to spin the key.

This was with a pump-key lock, but I think the method would work with a conventional pin tumbler type.

I think the video was on [url]locks.ru[/url], though I'm not certain.
