A springloaded circular tension wrench attached to the end of a pickgun may work especially if it has a dial scale so you can see exactly how much tensions your putting on the lock whilst using the pickgun. I have to get one of these as i can see them being of great use with a pick gun especially as you learn to recognise which locks require which tension. This could be made up quite easily with some tape to begin with.

Right im off to order a circular tension wrench.............

Peaky - maybe you should reconsider your signature line after looking at that photo

Peaky's new signature should now be:

I got a g spot tickler that can pick that!

[CSballer89]

i think i could probably make it but it would only be limited to certain locks because it would be a raking device, or i could make sets of them with the jagged edges

Hey Guys,

A variation of what you are talking about already exists and is made by HPC. It is not all in one though. It's various discs that go over the key profile that are spring loaded. The outside dial shows the amount of continous torque that is being applied. It's the TNT series under torque and tension wrenches. Check it out ar hpcworld.com

Your key word there is continuous. What we are talking about is a pick gun that will throw the pins all up in the lock and THEN suddenly trigger the tension.

That's the key to the proper use of a pick gun. Continuous tension causes the driver pins to bind, and prevents the gun from working as quickly as it could.

If you pull the trigger on the gun, and then quickly apply tension, the lock should turn. It's the angle of the pick needle and the timing of the tension that are the key.

For this idea, you would need to design a whole new pick gun.
I don't believe you can modify an existing one - we would need both the pick needle and the plug turner in the lock which makes some mechanical design problems.

Idea 1:
Using 2 separated mechanisms - one that hits the needle and triggers a second, spring loaded mechanism at the same time which turns the plug.
Seems pretty uncomfortable to me, because you would need to wind up the 2nd mechanism each time.

Idea 2: A combined mechanism where the heart is a sawtooth wheel. Turning the wheel lifts the spring loaded needle over the highest point of the sawtooth and then allows it to fall back, hitting the pins. The wheel's axis would be connected to the plug spinner so we would have turning and snapping at the same time.

Now comes a trick: The end of those sawtoothes doesn't have to be exactly 90 degrees. We allow to end it in a slight curve or angle, so that the spring loaded needle not only hits the pins, but pushes forward the wheel a little when snapping back.

Oh, give me a little time. I have a few designs on the go here.

bembels on to something, I like it, especially the slight flip at the bottom that would kick turn the plug. I always envisioned a varient of the split tensioner, connected to the plug at top and bottom of the keyway, this could be spring cocked by the same turn that cocks the probe, but it could also be controlled by another cog wheel on the same axle, offset from the one that drops the probe. possibly with the ability to ajust a little bit to make timing a thing the operator can ajust.

just an idea, if anyone's still following this thread,

why not use the end of the pick gun trigger travel to operate a tensioning device hopefully ths would create the time delay needed to apply tension to the plug as the pins are floating ?

just a thought and I've no idea how to make it at the mo.

This talks about something at least in my mind is dead on to the auto bumper or auto picker with added tension tool, in my mind it isn't to hard to get it to turn the lock a slight amount since, all you would do is have the tension tool, only act on the farthest part of the throw of either the pneumatic piston, spring, whatever, with a little tab that would only need the tension part of the device to turn no more than a millimetor or any designated distance, and then you would turn the cylender by and after it was opened.

As my research in each of things, it pretty much turns into a multipurpose bypass tool, since almost literally no user input is required for it to perform, it ends on idiot proof.

Other than pushing the button, lever, whatever and the pre-determined tension is applied to the strike.

I have had an idea i thought i would share with you all, i havent tested it out yet this i plan to do tonight,

What if a special pick tip was made that was almost like a tuning fork shape, this could then be inserted in the keyway so that one finger is under the pins and the other at the bottom of the keyway,

The single pronged end could be round and this could be fitted in a cordless drill chuck,

The cordless drill must be one of those that has the torque setting adjustment,

Once set on light duty the drill could be operated, but instead of the chuck and pick arangement spinning the torque adjusted just slips and gives that vibrating movement,

This system with either more torque, less torque, more speed on the mechanisim etc may be the style of thing we need,

If you hold a screw in the vice and try this out you notice that the chuck doesnt spin but vibrates every time the 'clutch' slips, when the cluch slips and vibrates the next thing is the mechs try to grip again and there is a slight (adjustable) torque applied to rotate the chuck, if it doesnt move the 'clutch' slips again and the process is repeated, this could give us the turn force only when we need it, after a pin vibrate,

The frequency of the slipping may not be quick enough hence speeding the drill up to make it quicker,

If it is too harsh maybe the mechs can be smoothed out a bit.

I will post my findings once tests are complete.

[Rockford]

Nice bit of "thinking out of the box".

Although the chuck vibrates when the clutch slips, would it release tension to reset overlifted pins ?. Is there a possibility of releasing correctly set pins when the clutch slips ?.

Would the vibration be sufficient to bounce the pins past the shear line ?. Would the vibration be absorbed by the cylinder plug rather than passed to the pins ?.

The "fork" shape would need to accommodate restricted keyways.

Let us know how you get on with your experiment.

Got called out twice last night so didnt get round to doing my tests, but Rockford your right about the pins, i hadnt thought about set pins dropping back,

Surley a good electric pick that is used to bounce all the pins at once and sets them all at once also runs into this problem where pins will drop in that instance as well, so this may not actually happen as much as we think,

I will still have a go at this even if only to eliminate the possability.
