AM3 AM6 BumpKeys

[awol70]

i cut these out of old keys that exceeded M.A.C.S.
on my new HPC key punch.
there will be many of these ,as i have around 100 keys to play with.

Alright then, tell me what M.O.C.S. refers to, and why.

Nice one awol - nice touch with those old keys.
simple affective device

nice job awol70
so as long as you have an old key or blank you can cut out bumpkeys?
or does it just take certian keys?
what does M.A.C.S stand for ?

catch ya lata have fun

Alright then, tell me what M.O.C.S. refers to, and why.

MACS =Maximum Adjacent Cut Specification (or Safety factor). Each manufacturer specifies the maximum difference in depth of adjacent cuts on a key. This eliminates the slope of one cut wiping out the root of an adjacent cut. For instance: You can't place a #9 cut next to a #0 cut on a Schlage standard key. There would not be enough blank left to support the #0 pin.

Incidentally, there is no MACS to worry about for BEST (and clones) IC Core keys, because of the spacing of the cuts.

well honestly..i dont know..=/
but could you tell me why factory cut American keys would exceed M.A.C.S.
in the first place?
this has always puzzled me.
isnt this extremely wasteful?

hehe.

m.o.c.s = Maximum Opposing Cut Specification

Winner!

opposing?
please enlighten me someone...??
i am thinking double sided/bitted keys...
this would make sense to me..
(so you dont have two opposing deep cuts ,resulting in a weak key...)

I have heard this term as well, and yes Awol I do believe your right, but I don't know for sure!!! two deep cuts opposed to each other would make a key that would be vulnerable to breakage.

maximum opposing cuts are where a key with 5 depths must not have a 1 opposing a 5, or if there are say 6 depths, you may be required to have a 1 opposing a 4, or a 2 opposing a 5, 3-6, etc.

The size of the cutout in the wafers dictate whether or not this comes into play.

It's used on double-sided keys, not convenience keys.


(two deep cuts opposing eachother would be Minimum Opposing Cut Spec, which doesn't really get used often but yes it is possible)

I hope that makes sense, I'm slightly hungover.

ahhhh,i see.
thanks for the clarification.
this one has been bugging me.
any idea on the reason factory cut keys would exceed m.a.c.s.?

I dunno...You seem to make better sense when you're hung over.
