BUMP HAMMER CONSTRUCTION - Easy and Cheap

Postby Black Zero » 4 Oct 2007 21:42

Intro
Heres a quick little guide to make an incredibly easy bump hammer with some local hardware store supplies. I've even found this one to be a bit more reliable compared to the one off of lockpickshop.com. This hammer requires no cutting, measuring, etc, so hopefully it should be easy enough for everyone.

Guide

Alright first step... go to the local hardware store. Here's a little inventory list with pictures to show you what to look for.

Rubber mallet - shouldn't cost more than $1
I don't know the exact name for this rubber thing, but I'll let you know if I do. Mines about 2" by 1" by 1", but it shouldn't matter if its a little bigger or smaller. If you want you can cut off the metal edge using a hacksaw, but this is not necessary if you don't have the tools

Bolt - again should just be some pocket change
Find one of the longer bolts to give you more leverage and make sure it fits into the threading on the mallet.

Electrical Tape - almost free
Now we can give the hammer a nice grip to feel good in the hands

And there we have it, an amazing bump hammer costing no more than a couple bucks and extremely easy to make. Let me know if you have any questions or need some help.

Can you get a decent whipping action with it?

Oh, and, dare I suggest, sticky?

Yea the whipping action is pretty decent :) and I think its the feel of it that makes it work good because I know in my head that the lock is going to turn making it easier to make it work (if that made any sense)

And surprisingly no its not that sticky, just a little at the end because bits of the sticky side of the tape turn up, but overall the tape feel works for me.

Good post and he wasn't asking if it was sticky he was asking if the mods would pin it to the top =)

I was looking into making one of these and a bump key or two to test out what the rave for these things are but I've been to lazy so far =)

haha boy do i feel like an idiot... i saw that as soon as i hit the submit button.
we really need an edit button pretty bad.

as for bumping i suggest you at least try it out, and even if you do prefer picking its a nice skill to have

One question what area (of the hardware store) did you find the striking head?

To tell you the truth I just had a bunch of them laying around in my basement. I'll make sure to go to the store sometime this week and find out what they are called and where you can find them though.

Playing golf with two old balls and a club with a long, whippy shaft?

what ever happened to bumping a key with a screwdriver, a regular mallet, or even a padlock? and not to detract from this topic (because it is a nice homebrew) but if you went out and bought a mallet, wouldn't that work just fine for the bump hammer?

well i can do just fine with a screwdriver or whatever else I can find, but its all about how often i can get it.

screwdriver - 1/3
my hammer - 4/5

and sure if you find a nice little mallet try it out, its all about preference.
