Original idea?

way ahead of you compadre

Then why didn't you pick up on the three shear lines, smartass?

Just kidding, San.

I had to leave something for you to post.

I think that if you had six of these in a lock, you are all of a sudden trying
to line up a huge gap with a fine shearline, which would be easier to do than
line up the small gap (no spring) with a fine shearline.

Do you see what I am getting at?
One quick rake (with anything) will line these springs across a shearline.
Then it is just a matter of turning the plug (with the now mangled springs).

Without the spring, I'd think that it is just a masterkeyed lock, which having
two shearlines, I would imagine would double the success rate of amatuer picking.

This sort of 'extra security' would quite probably be used in 'extra expensive'
locks and I for one would hate to part with a hundred bucks for a padlock that
is so easily trashed.

We all hate seeing some kid has glued a lock? Imagine the damage they
could do to one of these?

It would be against fire regulations or something too I'd imagine, if it was
to be relied on in some sort of emergency like used on a fire hydrant.


Sorry to be a wet blanket and I could be way off, but that is how I picture
the outcome of ME trying to pick a lock like that.

Well done anyway. You will very rarely make something new and excellent
without making a bunch of crap first, ask any true inventor.
(not taking the p**s, quite the opposite, encouagement.)

Good work anyway on your ideas.

PS, what if your springs had some sort of strong shell around them?
Or your two top pins WERE the springs, ie:

Code: Select all

The problem of having three shear lines this type of lock is not the problem with this design. If the driver pin and the ??? pin are the proper length, you could make it so that the "keyspring" (the spring in the plug) could not be lifted to the shearline.

Other than the problems mentioned already, it occurs to me that I don't think it would have the desired effect - namely, to make it difficult to determine when a pin is set. In a typical lock, when a pin is set you will feel a noticiable give on the plug at the moment the driver pin crosses the shear line. It seems to me that you would get the same feedback from this. If all other problems were addressed, I suppose it might frustrate the ham-fisted newbie, but I suspect that anyone with a reasonable amount of picking experience would feel right away when the pin is set, thus nullifying the desired effect.

I do also think that wear on the springs represents a serious problem in this design. In a normal lock, when the prings wear all that happens is you get less pressure pushing down on the driver pins (at least until they get really bad) but with this any amount of wear on the springs would represent a change in the bitting required to operate the lock.

At least that's how I see it.

I know it's kinda shmultzy at this point to say it, but I do commend you chaos for trying to think outside the box a bit.

This idea got me thinking. If the lower springs were moved into a chamber adjacent to the pin chamber then connected to a finger protruding from the key pins into that "spring chamber" so that there is always tension on the keypins, I think the result would be a lock that would behave as chaos envisioned without the problems with having the lower spring in the pin chamber.

Also the stiffness of the springs could be varied to confuse the picker as to which pin is binding.

P.S.
cha0s, as digital_blue said it is always good to see creative thoughts expressed.

I like that but then the "finger" coming from the spring cylander would either prevent oversetting a pin or if someone pushed hardenough i think it would just break and the lock would have to be replaced..

Ive got 8 hours of "work" today ill try to think of something
