Hello my Friends, welcome back
I decided to make this video because there are a few fellow lockpickers
who are now starting to pick the Tesa T60 which is this cylinder here
It's a dimple lock with 6 pins
and is very well made and dificult to pick Above all, it can be very difficul to pick at the beginning
I've been picking the T60 for a while now It's one of my favourite cylinders
and I thought that my experience could be useful to everyone here
to help them open these locks easier.
and this is the aim of this video
I hope that it wil lbe useful to you and that with what I am going to say
may help you improve on this cylinder
Ok, So why is a Tesa T60 so dificult.
The main reason is that it is so well made
which is fundamental
and because its pins are very well designed to make picking more difficult and they are extremely well made.
here I have a cutaway of a T6O
Let's zoom in
and have a little look at the pins
as yo ucan see, they are all the same they are serrated
and all of the drivers are the same too
But, what is the main characteristic that makes the T60 behave as it does?
The main reason in my opinion
we Will see if we zoom in an see more details
just there
is that the pins are bevelled at the ends
here at the end of each pin
is a slightly beveled edge
This is what forces us,
along with the high tolerances of the lock,
what forces us to use very high tension
The drivers are serrated,
and normally, when we have serrated drivers in a lock, we use light tensión,
but here, the bevelled effect dominates
and that is what makes us need high tension
so as not to over set the pins. The main function of these keypins is that they over set extremly easily
moreover, they have a serration which acts as an overset trap
and when you overset on, it catches on the shearline and is very hard to get back into play
it is hard to get back and all the others spring back into place
But as i said before, their main feature is that they are bevelled
and this is what forces us to use very high tensión so as not to overset the pins as we try to set them.
This is my opinion
Here we can see what effect the bevel has and how to interpret it
What problems do we all have when picking the Tesa T60?
The main problema is knowing the difference between a binding pin and a set pin
ok
How do we identify a binding pin?
A binding pin is one which is completely solid
it has absolutely no room for movement when we touch it, it is completely solid
this is the pin we need to play
the other pins Will move slightly
You will be able to budge the pins, very slightly, but they will move
let's zoom in
and I Will show you which it is, if i were picking, and if this pin were picked
here we can see
it moves a little it moves a Little bit too
it can move, that's all
if it goes beyond this Little movement – all the pins are solid,
but if it has this little tiny movement then it is set and we mustn't touch it If we touch it then we Will overset it
Why is it like that?
this is what i think is the most important and i would like you to visualize it
I have made a Little sketch It is rough sorry about that
but i think it can help understand what is happening
this is the driver with its serrations
and this is the keypin with the bevel, this bevel is just here
ok What happens when the pin is set?
When a pin is set,
the shearline is here
and thanks to the bevel, there is a Little margin for movement
here is a space that lets the pin move slightly when you touch it
this is the slight movement that we talked about before
and this slight margin is what we have to feel for when we are checking the pins
If a pin is binding, the shearline is here
and the pin cannot move at all and when you touch it it gives a click and mives here
and Will then have this little ability to move
most of the setting we try to do in a T60
are very short
The technique of picking a T60 consists in cycling through the pins,
first, second, third
just touching and everytime something binds, move it,
it gives a click, straight away, click,
and we have to stop pushing
If we keep on pushing the pin, it Will overset
With the T60, just like the TE5, you an't really set a pin in one go,
with just one straight touch of the pick
the movements of the pick need to be precise
press until you hear the click, then stop
therefore as we are picking we Will have several clicks
click, click, click,
when we press it and hear a click and the pin moves,
and it isn't solid anymore,
we have to stop if we keep pushing we Will overset it Why?
because the shearline is here
at the limit if you touch the pin, it springs
click
and if you keep pressing it to see if it is binding what you Will do is overset the pin
The bevel moves into the shearline and oversets
and if we hit the serration too, then it is game over
and you hear a click, a real Deep click, because we have really set the pin
but we are stuck here
and what you are going to notice is going to be
you are going to hear the pins springing, different things could happen,
but mostly, when you catch a pin here,
none of the other pins bind
This one remains solid, hard,
but none of the otheres bind, so we can't continue the picking, we need to release tension
when a pin binds
we need to visualize that the shearline, this is the most important, is here, or here, or here
and touching the pin, we are going to hear a click
it will go here to the shearline, or it will go here
and this space that is here, or this space that is here is what is going to give the pin a slight margin of movement,
a few tenths of a milimetre
here, what we have to clear up
we mustnt carry on pressing the pin if we carry on pushing and the shearline is here, we will overset.
Ok? and if it is here, and we continue pushing without it binding, we will probably lose the rest
So, this is the most important knowing what is happening inside the lock
the touches to set a pin have to be precise
press, and as soon as it clicks, stop
and move on to the other pins
so it is a systematic picking process
touch all the pins which is very important too
being sure to touch all the pins when there is a very short pin behind a very long one,
it stays hidden and you cycle through the stacks
you may pass over it without realising, so you need to count
first, second, third, fourth
Now, how to detect this little movement we have been talking about? often, tapping with the pick
softly, very softly
it is important to say, that although we are using very high tensión,
we have to tap the pick very softly
this is something that is very hard at the beginning
we are used to, if we use light tension,
tapping the pins carefully to not overset them
and if we work a lock with heavy tensión, we press the pins with a lot of force
But we cannot do this with a Tesa T60
When manipulating the pins, the touching to see if they bind or not has to be very gentle,
just troking the pin
for this, you need to deveolp a feel for it
and find that Little movement, those tenths of a milimetre,
that tell you that this pin is not binding and you mustn't touch it
One of the techniques that can be used if you cannot work out if it is moving or not,
is caress the tip of the pin forards and backwards
to listen to the noise it makes
I don't know if you can hear this sound
moving backwards and forwards with the tip of the pick on the pin
it makes a Little noise
and that tell you, if you hear that noise,
that this pin is moving and shouldn't be touched
A binding pin doesn't make that sound A binding pin is completely solid
boom, stop, very hard, and this is the one you need to touch
This is the base of the Tesa t60
identify this light movement to not touch the pin in question
and be methodical, touch, touch, touch, click, click, click, until the lock opens,
it will open in the end
but the pin movements have to be very short
there are only great movements when the shearline is here,
and we are trying to set, then it comes out of the serration, makes a spool-like movement
and goes into this serration or moves to the bevel, so is a large movement,
but whilst you are pushing you see that the pin reamins hard, when you hear a click and it becomes loose
it isn't solid anymore, then you have to stop
If you keep pressing, if we try to set the pin any more, we Will overset it.
this pin, when it is here, click,
it stays here,
and if we try and tap it more, to see if it is binding what we are doing is oversetting it, and we Will get here
and ruin the opening
ok
Now we know when a pin is binding
when a pin is set or not, it moves a little, and when a pin is overset.
We Heard a click, it seemed set,
and none of the other pins bind
this is the key, the others don't bind
I think that is the most important
Using your feeling
feeling to find the Little movement on the pin, very slight,
or even using your hearing
caressing the pin, what you are really doing is
rubbing the tip of the pin with the pick hearing this click click that it makes
which tells us the pin is set and we shouldn't touch it
ok, what else
One of the things you often do at the begining is set the tension far too heavy
this means you are going to get tired quickly
you can't open two T60s
because you have the wrench biting into your hand
you don't need to use such high tension
If you feel for this light movement on the tip of the pin
you can open a T60 with high tension, but a confortable one
So we need to let off tension,
not as a way to fix a problem
like getting back a completely overset pin,
but more as a picking technique
we are picking with high tension, but not excessively high,
and we accidently overset a pin a little
here we are
What is going to happen is that we are suddenly going to notice that no pins are binding
what we are going to do is reduce the tension lightly
to se if anything moves and try it again
In my opinion it is better to get used to a realtively high tension,
and let off tension to help pick,
rather than use such heavy tension that
you only get feedback through the pick, otherwise,
with a more moderate tension
you get feeback from the wrench too,
and you notice slight movements on the wrench when you set the pins
In the other way, you use so much tension
that you don't feel anything
In my mind it is more logical to get feedback from both tools, the wrench and the pick
It may be hard at the beginning, but it is the best way to pick a T60,
and i can pick 4 T60s one after the other
If your tension is too high, it is imposible,
you open one, and you can't pick anything afterwards
lastly, the pick itself
Use a suitable pick
that has a flag which is long and thin enough
These are, in my opinion, the important features of the pick
I use this,
which has a pointy shape " Hake tooth" and is very thin
Why?
Because the T60, although it has a simple keyway, isn't really that simple,
it has two bits of warding which are very high and close together, which protect the pins really well.
I am going to tray and show you from the back end
the first pin is right inside
and we can see the last from here
I am going to try and putt he pick in
here it is,
see there
as you can see, the pin is well protected by the warding
Now i am putting it right in
The pick needs to be small enough, but with a flag long enough to set the pin
can you see that the flag can turn and go almost vertical
the size of the flag can be at this height
which covers the keyway from the top to the bottom,
this is the size of the flag
Excuse me I have been talking a lot
But the idea is to try to pass on a bit of
what I have been learning by picking T60s
and that it may help you open them more easily
So then, let's finish by trying to get one open, i'm going to pick up all this,
put the cylinder in the vise and we can try
Ok, I have a T60 in the vise Let's try and pick it
to keep the vieo as short as possible
I'm going to use this commercial wrench
and the pick I showed you, with the thin flag
The picking is methodical touch all the pins
very gently trying to find a slight movement on the tip so as not to touch it
or a completely solid pin to touch
here we go
One, a click
Two, a click
three a click
four a click
Six a click
one
six
two
three
six
one
as you can see tapping very gently, without any large movements
two, three
five is binding
there, a click
six
one, two
three
five, six
one, two, three
six
Five is very short
one, two
five
one, two
six
five, that gave a good movement on the core
and after that movement, it opens
I went very quickly
to avoid making to video too long
i'm going to take it apart and see what is inside
let's go
ok, as you can see, I did a speedy gutting
just so you can see
that it has the same kind of pins
I showed you before
I hope you have enjoyed this video
and above all, i hope it has been useful
Sorry for the length of the video and that i spoke so much
But I had a lot to say and didn't want to leave anything out
I hope that some of what i have said will be useful to you
Thanks for your time, and goodbye for now
