Bump Key HAMMERS--please post ideas, designs, pics, info etc

wraith: Barry Wels wrote a great whitepaper on bumping. You can find it on the TOOOL website (www.toool.nl). But basically, all they need to do is set up the key machine to cut to the deepest cut for the particular key they are cutting (not always actually a 9 cut... kwikset is a 7 if I'm not mistaken), but put a thin metal shim against the bottom of the key blank so the code cutter will cut just a little deeper than the normal deepest cut.

Once they've cut the keys for you, shave a small amount off the tip and shoulder of the key and away you go.

Hope this clears it up.

Cheers!

Okay, maybe I was over thinking this? thank you DB, yes, that makes sense!

Looks like I can put away the "special helmet" and I won't have to ride on the "short bus" again

I use a small wooden block with cotton on it then i wrap it in electrical tape. i also use a rubber ruler with a wooden block on it wrapped with electrical tape. hey my friend has a 1 yr old and that is all i could think of. it is quite effective.

The kwikset is 666666 cut I have one, 5 pin key

[Auto45]

Take out one 6 sorry but it is a 5 pin 6 cut

Um... I dunno. Maybe I'm missing something, but this is the space and depth chart for Kwikset:



It would seem there is a 7 cut, no?

Maybe that chart is considering "1" to be an uncut spot.

[digital_blue]

If it were, I think it's the only key that'd be true for on the chart.

... hrr?

[digital_blue]

What I mean is, I've used the chart that that one came from several times. The charts from it for Weiser, Schlage, etc all have a 1 cut as a 1 cut, not a 0 cut. So I don't think that the chart is counting the #1 as a 0 cut.

I'm presuming I understood you correctly. Correct me if I'm wrong.

Technically, kwikset is 0-6 .: creating 7 pin sized - 1-7 if you may.

OR

I am totally wrong and :

kwikset #0 cuts are like lockwood #0 cuts and do not require cutting as the correct cut is the same height as a blank.


I am not to sure but i have an 0-6 kwikset guage, though there are no sizes to be found.

[webidiot2]

The #1 cut in kwikset is a cut there is no #0 cut.

Here's my ideas so far:

Sorry for the cross posting, but if people find this thread in the archives in the future, it may help.

did anyone ever get a definitive answer on what the true tomahawk striking surface was made of?

I have some funky "plasticy" stuff that has a weird grey look to it almost exactly like the real tomahawk, I also have some nylon, delrin and weird fiberglassy junk.

just a thought: did anyone ever try and make a handle out of the plastic from those plastic rain gutters? It seems like a very similar yet easy to obtain material.

another thought: how about an aluminum face? it would be softer than brass keys yet perfect to transmit the "shock" not mention very plyable and not suseptable to crack like the harder plastics.

just brainstormin' : )

Here's a new idea, I think...didn't search. Using a standard Arrow JT-21M staple gun ( no staples in it of course ), and a tie wrap in the keyring hole of the bump key to protect the key from getting cut by the impact. The tie wrap will eventually be cut instead, way less expensive than a new bump key. A tie wrap around the shoulder of the key also would protect the keyway of the lock as suggested elsewhere, in KaBump thread I think. With just a feather touch of turning the key in the desired direction and firing the staple gun to provide the impact...bingo...the lock opens every time.
