My first master bump key!

[Shrub]

Yes you are right as i say but there has to be an instance where this can happen, he says the key pushes in and out and i believe him or else there would be no piccy of it and there would now be a thread on getting a key out of a lock dont you think

If the bottom pin only hangs down to a set height then anything below that height or even slightly bigger will travel under the pins, maybe not smothe as a baby's bum but can happen,

If the cuts were a little wider then that key isnt coming out or gogin in anymore than the first cut i agree but if its in a certain configeration it wont be an issue,

On paper and in theory you are 100% correct but in experiance it can and does happen where such things work,

[mercurial]

Thanks for the reply & explanation.

I really don't think the key pictured could be inserted fully in any new lock with the M1 keyway, nor removed after partial insertion... I must agree that even if something seems 100% correct on paper, it might not always match real-world experience. Theories on paper do have their limits.

In the case of this key I strongly suspect we lack a thread about this key stuck in a lock because the lock it goes into and comes out of has been bumm(p)ed to death, to the extent where the key pictured DOES go in and out

*yawns* its getting hard to focus on the screen...definately bedtime for me

that key may have the 'canyons' cut too narrow for the pins to enter them and jam the lock, the pins may be riding only on the tops of the key, and as shrub said, the key that fits may be high cuts and in this way the thing would work for a while until the hammering causes some pin to drop in if a part of that comb is bent, then you have the jammed lock.

Good morning shrub

Yeah it amazed me that the key fits you would think the bottom pin(key pin) would get stuck in the when i try to pull it out,but amazingly it dosent.

Shrub i cant use the link that you gave me because my adobe reader dosent work.

I plan on going to the lock smith and have him make me a few copys so i can make better bump keys.

Thanks for your helpfull critizism

Walking into a locksmith shop and asking for bump keys will likely not get you far. Go to wal-mart and but some M1 keybkanks.

No i mean i will take me original key that turns the lock copy that and file down to desired dimesions

[Shrub]

Hey ray, you enjoying the sun while im enjoying most of the country under water?

Yes taking your working key to be copied is the best thing you can do,

[Eyes_Only]

Thats what I used to do before I got my own key machine. When I first started to experiment with bump keys I just took a few keys like for a Schlage and Master Lock with the deepest cuts and took them to a lockshop to have them copied so I'll have a few extras in case I made a mistake in the filing process.

But I only really did that once cos I got quickly bored with bumping after a few days. I only now picked it up again because I finally fashioned a decent homemade bump hammer.

Here is the copied key i got from the locksmith,I filed it down and i think i am getting better.

Print this at varying scales until you can lay a blank key on the paper and they match in size. Then use this as a template.

[Wrenchman]

Yea well much better, congrats, I told ya you just needed practise!

But don't worry, you just need practise, keep it up!

Can you not see why this is still worse than the first one you showed us?

Until you can notice the detail like that and understand what bumping is, how a lock works and how bumping works then your gogin to go around in circles over and over again,

I apprechiate Zekes help in this and its most excelent but your still not gogin to learn are you, if you simply copy that key then sure you will be better off but you wont know why,

You need to read up everythign you can on the subject and not only understand the princibles of how it works but the princibles of why they dont work when they dont,

Not doing you down Zeke, thanks for the pic there can now be a direct comparrison,

[Wrenchman]

Atleast the peaks are, or so it looks like, 45 degrees and it seems to be smooth!

Good job for 3th attempt!

I agree Shrub. I was hoping he would just use the pic as a guide in making his next one but figured I might as well tell him he could scale it down and use as a template. I think once he sees a properly cut key in his hand he can duplicate it easily by hand with no template.

Keep up the practise on the filing. It is a handy skill to have to be able to create a proper key with nothing more than a file and a set of small vise grips .

[Eyes_Only]

I think he did do a much better job this time around. The peaks are still a bit too high but the spacings in between looks more even. Major improvement.
