The Next Phase of Bumping - 'Spring-Bumping'

[ukbumpkeys]

I know you lot always think I'm advertising but if you have any interest at all in bumping I think you'll appreciate the information, pics and vid I've got for you here.

We're calling it 'spring-bumping' or 'bouncing' and it involves inserting the bump key through a small compression spring (wire width 1 - 1.5mm , wire length between 3 - 8mm seem to work best). Then you've basically got a semi-automatic bump key. here's a nice pic of one of our keys with a LOXPRING (our name for them) over it.


Basically, you don't need to keep resetting the key for every 'bounce'. You have to hit it a bit harder than convential bumping and it has no grace of the 'swing and clip' bump technique we've been promoting over here. But it works, you just repeatedly strike the bump key whilst using an on/off on/off 'turning pressure' on the key. A friend of mine has added to it by putting a tension tool into the key and I've put a link to his vid too. I'm using a bump hammer I designed I call the LOXWAT (lock-swat), which is stiffer than others on the market and has a heavier 'head'. The head is in fact steel but has a rubber pad stuck to the face.



Here's a vid of me doing some spring bumping:

Here's someone on my forum who gave it a go too. He's using a wooden mallet which has the necessary weight for 'Bouncing' too. This is the one with the tension tool. I'll try and make a video which shows my on/off 'pulsing' technique. You 'weoodpeck the spring-bumpkey and synchronize the on/off turning pressure, almost the opposite of traditional bumping:

Tell us what you think, things are really moving on for UK Bump Keys and we want to know what you think.
PLEASE don't ban me! This information is really cutting edge and how else can I share it with you without telling you about it? If you're gonna ban me, just delete it instead, I get a lot of help from your friendly members and don't wish to lose the resource

seems pretty interesting

[xnoobandrew]

do you hit all the pins tho? And also the same technique?

If so, this will probably be a very effective and useful way for locksmiths and burglars to get into houses..and other locks.

[ukbumpkeys]

I don't understand what you mean by 'do you hit all the pins?' The key bumps as normal (occasionally, if using a six pin bump-key on a five pin lock, you're effectively getting a bump on the way in and one on the way out, so if you set trhree fgoing in, you might set the remaining couple coming out. All the spring does is 'reset' the bump-key'
Less than 2% of Uk domestic robberies use the front door as point of entry, I wonder how many of them used a bump key? Is this really an issue? If it were, then surely this entire site is called into question.

These diagrams might help

spring is interesting, but how does it test against the hot glue, or simply offset bumpkeys?

Seems like this is more hassle than either of those two methods, though I could be convinced you can bump more rapidly with this, but it seems like it would be negligible.

[bumpit]

I like the idea. Very fast if u need quick entry for some reason... This guy knows his stuff on bump keys. He taught me a lot

[zeke79]

It could help. I have done something similar to this with surgical tubing but have always gone back to a properly prepared bumpkey.

[Eyes_Only]

I think a key for an American lock like kwikset or schlage would require some serious filing and reduction of the shoulder and bow area depending on what size spring you have. But I could be wrong, I'm not really a big fan of bumping anyways.

[zeke79]

You are exactly right. That is the downfall of this method.

[JackNco]

huh
Thats an interesting idea. the spring looks like a shorter version of the spring that pushes the latch on a BS mortise. i usually try and avoid bumping but i just have to give this a go now. cheers for the info.

All the best

I like the idea, But the key in the first picture looks very crude and looks potentially damaging to the pins even after 1 hit.

Also, To get full advantage of the spring, would the end of the key not need to be filed off at all?

What if you took a 6 pin key and made the spring just slightly longer than the space of the cuts and used it on a 5 pin lock? This would require no modification to the shoulder.

But how many locks out there have the same wards between a 5 and 6 pin barrel?

But how many locks out there have the same wards between a 5 and 6 pin barrel?

I'd say over 90% of the locks in my area.
