*Bump Keys are ON SALE*
My Homemade Bump Hammer
Posted 06 March 2007 - 12:09 PM
Supplies + Cost
1.) Rubber Stopper (RS-8 (Ace Hardware)) $0.85
2.) Hack Saw blade (Flex Type) $1.29 (They all flex/bend, but the ones that say FLEX on them, won't snap on you)
3.) Electrical Tape + Rag/Cloth $1-2 (if you don't already have it laying around.
4.) Small screw.
Ok, Since the hacksaw blade already has a hole in it, no drilling is required, just center the hole on the stoppers WIDE side and pop in a short screw when it gets close to being all the way in only use 3 fingers to tighten, DON'T OVERTIGHTEN ITS RUBBER If its solid you got it right.
Wrap the lower couple of inches of the hacksaw blade with some electrical tape, wrap it with a small piece of rag/cloth etc... Then wrap with some more tape!
And your done! You now have a bump hammer that has improved my bump rate from 4-5/10 to 9-10/10 times..
Here are some pics of it.

The surface area is smaller but it seems to smack back like the Tomahawk. I am still not having much success, though. I've tried the handle of screw drivers, spoons, butter knives, and whatever else I could find and I am having very little success in all. I've successfully bumped one lock twice out of 30 or so tries with this new hammer, compared to three times out of 400+ tries with the back of a screw driver.
What in the hell am I doing wrong?

btw, these are the hammers i made the other night for 1.50$ using a ruler and a cutting board.... they seem to work pretty well as i get my keys more refined. (they're kinda ugly tho)

On a side note, I made my first bump key using hand filers last night in my new vice. I actually got it too work using my USMC Ka-Bar as a bump hammer (hence my user name ) on my Brinks medium security 40mm padlock w/ spool pins . A tip for the newbies like me, if you want to get hand filers, get them at Harbor Freight Tools. I got a 6 peice set from Lowes that cost $16.97 compared to the 12 or so peice set at HFT that cost right around $8 bucks... And yes, I did look at them both closely, different packages but they are the exact same thing!

I am going to try this hacksaw blade idea too, soon.

The stoppers were at my Ace hardware in the section where they sell loose nuts and bolts (in slide-out boxes).
This thing works great. It revealed to me just how little controlled force is required to bump a lock. The force can be controlled by varying the swing and positioning ones thumb at various points along the exposed portion of the hacksaw blade.
It is important to get the screw perfectly centered in the stopper. A trick I used was to trace around the wide side of the stopper, cut out the circle of paper, and fold it in half at different points twice. The point where the creases intersect is the center. Use the paper as a template and mark the center of the stopper by pressing the pointed sheet metal screw through the paper into the stopper.
