5 in 1 lever pick gun

[cbuk2k]

Has anyone ever considered a pick gun for a lever lock? I was thinking you could make a sort of 5 in one pick. That or something which would go through every combination? Lever locks don’t seem to have many, I’m thinking something like a curtain pick with a bored out centre then slot 5 rods down the middle with there ends bent to 90 degrees.

If they could all be aimed in the same direction the would slot through the key way. The other end would also be bent and then connected to servos or a simple gear box. You could also take advantage of the symmetry in the key.

Yes i suggested this a few years ago but it wasnt practacable, the details can be found on this site as i saw the thread a few nights ago while i was looking for another idea i had posted,

Think I’m going to fire up the CAD package because I think it could be done. Might be a bit specific for a certain keyway/lock. Have you any idea what it was called? I did have a bit of a search about before posting.

I cant remember, i think it may have been 5 in 1 pick or somthing, its not practacal for a number of reasons some being that material stock is a pain to source of the right size and strength and the othe rmain reason is that its totally unsuitable for curtained locks especially those with low levers,

Case hardened spring steel is pretty tough stuff, materials aren’t really an issue (I have a find that is shift engineer at a steel works). I am buying a lathe at the moment and have in the past made clock movements so I’m not that daunted by the turning.

I believe the curtain is attached to the bolt so you could move it with this instead of a bolt thrower as with a conventional pick. This would mean the tube didn’t have much strain on it.

Maybe have to pass the keyway and then turn.

Sorry

dam that photo bucket! this should work.

Do you have a BS lock? if not go buy one and strip it down before you spend too much time on this,

Im not sure what spring steel is used for in this but ill leave you to have a go,

[cbuk2k]

I have a couple of 5 lever locks with curtain, they are BS but not sure if they are the latest revision. I had planned to use spring steel for the picks and the sleeve. It has a good tensile strength and mod elasticity. May use mild or stainless for sleeve start at 10 mm it always seems better to bore something out and turn down if you want a thin wall. I’m not thinking commercial product here. Just an interesting way to waste a few hours.

Couldnt you use something to vibrate the levers into place if you could get it inside the lock

[Shrub]

Well good luck with that, be sure to show us the finished product,

[cbuk2k]

Definitely worth a though parapiolet. Trying to tank of something a bit like a chimney sweeps brush. Maybe cut slots in a round bar so you could slide them in a section at a time length wise.

I will do Shrub prob a failure but if you learn in the process can only be a good thing.

You can get the dremmel extention that would take a rotory tool into the lock. Something like a garden strimmer on the end but something more substantial. I think its a very long shot but interesting all the same.

Lever locks vary on the way the bolt is thrown back in security locks.
Most of the bolts are thrown by the key but some have the curtain sliding the bolt back.
Then there is the different kind of keys, the solid key and the hollow or tube key that goes around a post in the lock.
I'm not sure a vibrationary action would be suitable for lever locks as it's more a lifting action that is required.
A.C. Hobbs and his picking of the Chubb lock at the 1851 London Exhibition may be of interest to you if you can find a picture of the tools that he used.

Do you mean a pick gun using a similar principal to a pin tumbler pick? I don't think i'm revealing any new information here but the pick gun works on the fact that the bottom and top pins are separate, and can be "bounced" apart, creating a gap, the same principal would not work on a lever lock.

Lever locks, despite being old designs, are quite secure and especially in locks like Chubb 3g110 and 3g114's, they keys need to be VERY accurate.

If any of you have cut them, and i'm sure some of you you have, you'll know what i mean.

Just my .02, it's good to see so many minds thinking so creatively. I mean hey, without people like us, maybe things like bilock or Abloy protec would never have been invented!
