The Next Phase of Bumping - 'Spring-Bumping'

[JackNco]

before i was using brass keys i snapped a shoulder and drove it in to the key way. i swear i kill more locks than some of the driller killers lol

i accually made my own out of old springs that i've been pulling out of stuff for years and cut the keys on 6 pin blanks and just pull the key blank out two spots on a 5 pin and one spot on a 6 pin and change up with longer springs and ones that have just a little more tension to them...............hope i dont get in to much trouble for this post.

Interesting posts, I appreciate the effort, and any criticism is good gfor the field.
Regarding the 'filing' of the shoulder, I take my keys right down at the shoulder anyway. I then use either a spring or a washer as a 'dampner'. I use either a red 3mm fibre washer, or a 2mm rubber washer. I can mix and match these to give me 3,4,5,6,7,8mm dampners over the shoulder. Some locks respond well to springs, some to rubber washers, some to fibre washers. I ocassionally use a flat steel washer behind the spring too. In the picture, you can (just about) see I've used a beaded cable tie to keep a washer with a key. Quite handy. You'll also notice the key looks like a puffin. That's just that.
The other picture shows a few of my bump keys. I'm very proud of the range of patterns I've managed to create. And they all have their uses. Different patterns can sometimes mean the difference between a lock bumping or not. Enjoy (try and zoom in, as the resolution is better)
cheers



Here's the various bump-patterns I referred to.

interesting but i cant see why the last 2 would make any difference when spring bumping... i haven't tried it yet but ide imaging at that speed the pins are not following the tops of the key at all.

ive found the best way to bump gege
i push the key in all the way then tap and turn tap and turn and it goes pretty quick.
weird as thought you had to pull out one pin.
any idea why this works better on gege?

[JackNco]

thats called the "minimum movement" method. basically you shave about 1.5mm off the shoulder and tip of the key. its the method developed by toool (www.toool.nl)

oh ok, i just got lucky there then.
it seems to work better for me
i can see myself bumping everything on warrants soon
save me charging my electric pick.
makes a mockery out of lock picking
a full set of bs,decoders and bump keys and anyone can do warrants
i might train a monkey and sit on my arse all day.

Doesn't look as good though. banding a key with a hammer in comparison to using an EPG. less professional, but thats just my opinion.

Yes, those bumpkeys are sure to be a big help when you meet a profile you don't have to hand.

If you don't want to keep charging your EPG, send me your HPC and £100 and I will turn it into a beast of a machine that will work all day and only need a recharge about every 4 hours of run time. It will do a heck of a lot better on opening things, too.

There is no perfect tool for opening doors. And saying "With a full set of BS tools" is madness, as that's going to be £3K at least before you start.

[peacefullockie]

yes true.
i havent even got a 114 decoder yet.
id like the 110 as well and the profit.
ive got the securefast one.
a chris belcher pick which does most for me gauge 5 wise.
jack n o?
do you know e*yd*N locksmiths?
they are from your way.

[peacefullockie]

how do u super charge a hpc electropic then?

[JackNco]

NKT Loves his EPG, hes mentioned it a few times. a few members have don't the same thing. i don't know many details but sounds well worth it.

[NKT]

Well, it's more involved than people might think, but basically a bigger capacity battery that runs a bit hotter and never goes dead in your toolbox. Even if you leave it a week in a cold van.

Works wonders.
