bump keys - cut to code

[skold]

Hmm, i have never noticed that code machines have an A/10 cut for C4.

Instacode?

[Mutzy]

yeah, it should come up on the machine's display of the available cuts.
i.e. 0123456789A

Any other aussie lockies comfirm this? I'm going from memory here.

You know those little plastic covers you get for keys? slip it over your key and then twist it round to go ver you adapted shoulder, this works well and doesn;t need replacing too often, well never as yet but I can see it coming. It's also a good way to color code your bumpers

I was considering the idea of a hard washer or disc that has a slot cut to fit all key profiles (just a rectangular cut). Then you cut-ahead (or shoulder) your keys to make up for the width of the disc.

I was originally thinking a hard nylon, but that would be too custom and probably still wear out too quickly, so perhaps a plain old steel washer from the hardware store with a bit of dermal work.

You may like to try and see if a fibre washer does what you want,

[Raccoon]

Where does one obtain a fiber washer?

[Shrub]

An engineering supplies place, a auto supplies place, a washer shop, ebay, washersRus lots of places,

[mastermarc]

as far as the washers go you probably right about nylon. I would instead go with something that will get messed up BEFORE the lock face. So steel might not be good because it might be stronger then the lock face. You might end up with a circular imprint on the lock face. The best would be copper, second would be brass. Either way you should find a way to punch them so you can make a bunch easily.

I have heard of people using duct tape in a thin layer to cushion the key. The MIT guide to bumping has an idea for cushioning keys also but I cant recall exactly what

MIT Guide to bumping?

[Romstar]

I'm with D_B on this one. The MIT what?

I am no expert on this but this is what I was thinking of doing to prevent the plug from getting too battered.

As someone else suggested make a flat round disk and cut a profile in the middle the same size as the shoulder of the bump key. Then braze or weld it onto the shoulder of the key. One could also position it so another disk of softer material could be place on it as well to prevent the metal on metal contact.

rapping or ( bumping) has been around for a while, am gonna use a SCHLAGE lock for this example. cutting too the chase, you cut your " bump key " to the deepest cut and pull out a click then rapp the end of the key with a tool of some sort. a better way is after you cut your "bump-key" file about 1/32" off the shoulder and tip of key.NOTE: you'll have the correct bump-key when as you insert the key into the lock, the key pushes out a little.

hi i have found that using a small piece of hot-glue-gun stick as used by barry from toool works very well on both the MUL-T-LOCK type dimples he shows & regular YALE type locks.

[franko452000]

i seen that video with the " glue stick " but i can't remenber what he was doing, anyhow i loved the trick with the " foil-tape ". we have a machine at work that uses a dimple lock, first and only one i have seen. those germans are sure spilling there guts to any and everyone about bypassing all types of locks.!
