Bumpkey Tutorial By MasteR (typo edited by Varjeal)

Postby ThE_MasteR » 4 Oct 2005 19:30

I just made up a quick tut on how to make a bumpkey. I did this with with my Dremel, and I have to say this was easier than with a file..

What you will need:

A Rotary tool ( Dremel )
A Pack of Cut-off Disks
A key Blank (..Of your choice )
A cold drink :wink:

First step, ( whatever that's in red, means it needs to be cut )
Take your original key, and mark where the cuts are like in this picture.

-------------------------------------------------------------------------------------
Next,

Cut a " line " of about 1-2mm thick down where the marks of the cuts from the original key are like so,
Image
-------------------------------------------------------------------------------------
This is what it would be supposed to look like after the cuts are made,
Image
-------------------------------------------------------------------------------------
Now,

Cut a straight line thru all the peaks, try to make the line in the middle of the peaks like this,
Image
-------------------------------------------------------------------------------------
This is what it is going to look like after the cuts are made,
Image
-------------------------------------------------------------------------------------
Next,

Cut diagonal lines on the peaks like so..
Image
-------------------------------------------------------------------------------------
Do this on the other side of the peak also..
Image
-------------------------------------------------------------------------------------
This is what it should look like after the cuts have been made to the peaks, the bumpkey is almost finished.
Image
-------------------------------------------------------------------------------------
Now you wanna be carful here. You need to remove a little bit of metal on the head, and a little bit of metal on the shoulder. I find that taking off 5mm on the shoulder works, and 0.2-0.3mm on the head works ok, but this could work better your own way, this is just my way :wink:
Image
-------------------------------------------------------------------------------------
Here's the final result on the key..
Image
-------------------------------------------------------------------------------------

So I hope this will help all the people that are willing to make some bumpkeys, and think they can't. Well here's another great method for making some, and it works !

Also if there's somethings that could make this tut better, simply tell me and i'll edit it with pleasure.

Cheers :D

Don't forget to smooth the hills slightly.

I was waiting to see how long the title error took to find. Oh well... lets all keep it PG-13 or so.

Very nice tutorial Master :)

Now, I'm new to this whole "bumkeying" haha...bumpkeying, is it just a key that you put in the lock and move it around kind of like a pick and hope it opens the lock?

Typically how many times would you expect to be able to use a bumpkey before it stops working?

it is used to gain access, not to use repetitively. will damage a lock fast... another of my Tri-circles lies dead somewhere in my shed as a result :D
my lock withstood 2 hours before it died :P

if you're talking about the bumpkey itself I reckon it would last a good while, really depends what you use to tap it in the lock...

but yeah nice guide... well done
