a
series
of
exercises
that
will
help
you
learn
the
basic
skill
of
lo ck
picking.
Some
exercises
teac
h
a
single
skill,
while
others
stress
the
co ordination
of
skills.
When
you
do
these
exercises,
fo cus
on
the
skills,
not
on
op ening
the
lo
c
k.
If
y

8.1
Exercise
1:
Bouncing
the
pic
k
This
exercise
helps
you
learn
the
skill
of
applying
a
xed
pressure
with
the
pic
k
indep endent
of
ho
w
the
pick
mov
es
up
and
down
in
the
lo ck.
Basically
y
ou
wan
t
to
learn
ho
w
to
let
the
pick
b ounce
up
and
down
according
to
the
resistance
oered
by
each
pin.
How
y
ou
hold
the
pick
mak
es
a
dierence
on
how
easy
it
is
to
apply
a
xed
pressure.
Y
ou
wan
t
to
hold
it
in
such
a
wa
y
that
the
pressure
comes
from
your
ngers
or
y
our
wrist.
Y
our
elb
o
w
and
shoulder
do
not
ha
v
e
the
dexterity
required
to
pick
lo cks.
While
you
are
scrubbing
a
lo ck
notice
whic
h
of
your
join
ts
are
xed,
and
which
are
allo
w
ed
to
mo
v
e.
The
moving
joints
are
providing
the
pressure.
One
wa
y
to
hold
a
pick
is
to
use
t
w
o
ngers
to
provide
a
pivot
p oint
while
another
nger
levers
the
pic
k
to
pro
vide
the
pressure.
Which
ngers
you
use
is
a
matter
of
p
ersonal
choice.
Another
wa
y
to
hold
the
pic
k
is
lik
e
holding
a
p encil.
With
this
metho d,
y
our
wrist
provides
the
pressure.
If
y
our
wrist
is
providing
the
pressure,
your
shoulder
and
elb ow
should
pro
vide
the
force
to
mov
e
the
pic
k
in
and
out
of
the
lo ck.
Do
not
use
y
our
wrist
to
b oth
mov
e
the
pick
and
apply
pressure.
A
go o
d
w
a
y
to
get
used
to
the
feel
of
the
pick
b ouncing
up
and
do
wn
in
the
k
eyw
a
y
is
to
try
scrubbing
ov
er
the
pins
of
an
op en
lo ck.
The
pins
cannot
b e
pushed
do
wn,
so
the
pic
k
23
must
adjust
to
the
heights
of
the
pins.
T
ry
to
feel
the
pins
rattle
as
the
pic
k
mov
es
ov
er
them.
If
you
mov
e
the
pick
quickly
,
y
ou
can
hear
the
rattle.
This
same
rattling
feel
will
help
you
recognize
when
a
pin
is
set
correctly
.
If
a
pin
app ears
to
b e
set
but
it
do esn't
rattle,
then
it
is
false
set.
F
alse
set
pins
can
b
e
xed
b
y
pushing
them
down
farther,
or
b
y
releasing
torque
and
letting
them
p op
bac
k
to
their
initial
p
osition.
One
last
word
of
advice.
F
o cus
on
the
tip
of
the
pick.
Don't
think
ab
out
how
you
are
moving
the
handle;
think
ab out
how
you
are
moving
the
tip
of
the
pick.
8.2
Exercise
2:
Pic
king
pressure
This
exercise
will
teac
h
y
ou
the
range
of
pressures
you
will
need
to
apply
with
a
pic
k.
When
you
are
starting,
just
apply
pressure
when
you
are
dra
wing
the
pick
out
of
the
lo ck.
Once
you
hav
e
mastered
that,
try
applying
pressure
when
the
pick
is
moving
inw
ard.
With
the
at
side
of
y
our
pick,
push
down
on
the
rst
pin
of
a
lo ck.
Don't
apply
any
torque
to
the
lo ck.
The
amount
of
pressure
you
are
applying
should
b
e
just
enough
to
ov
ercome
the
spring
force.
This
force
gives
y
ou
an
idea
of
minimum
pressure
you
will
apply
with
a
pic
k.
The
spring
force
increases
as
you
push
the
pin
down.
See
if
you
can
feel
this
increase.
Now
see
how
it
feels
to
push
down
the
other
pins
as
you
pull
the
pick
out
of
the
lo ck.
Start
out
with
b oth
the
pic
k
and
torque
wrench
in
the
lo
c
k,
but
don't
apply
an
y
torque.
As
you
draw
the
pick
out
of
the
lo ck,
apply
enough
pressure
to
push
eac
h
pin
all
the
wa
y
down.
The
pins
should
spring
back
as
the
pick
go
es
past
them.
Notice
the
sound
that
the
pins
make
as
they
spring
bac
k.
Notice
the
p opping
feel
as
a
pick
go
es
past
each
pin.
Notice
the
springy
feel
as
the
pick
pushes
down
on
each
new
pin.
T
o
help
y
ou
fo cus
on
these
sensations,
try
coun
ting
the
num
b er
of
pins
in
the
lo
c
k.
Do or
lo cks
at
MIT
ha
v
e
seven
pins,
padlo
c
ks
usually
hav
e
four.
T
o
get
an
idea
of
the
maxim
um
pressure,
use
the
at
side
of
your
pick
to
push
down
all
the
pins
in
the
lo ck.
Sometimes
y
ou
will
need
to
apply
this
muc
h
pressure
to
a
single
pin.
If
y
ou
encounter
a
new
kind
of
lo
c
k,
p erform
this
exercise
to
determine
the
stiness
of
its
springs.

Exercise
3:
Pic

T
orque
This
exercise
will
teach
you
the
range
of
torque
you
will
need
to
apply
to
a
lo
c
k.
It
demon-strates
the
in
teraction
b
et
w
een
torque
and
pressure
which
was
describ e
in
c
hapter
5.
The
minimum
torque
you
will
use
is
just
enough
to
ov
ercome
the
ction
of
rotating
the
plug
in
the
h
ull.
Use
your
torque
wrench
to
rotate
the
plug
until
it
stops.
Notice
how
muc
h
torque
is
needed
to
mov
e
the
plug
b
efore
the
pins
bind.
This
force
can
b
e
quite
high
for
lo cks
that
hav
e
b
een
left
out
in
the
rain.
The
minimum
torque
for
padlo cks
includes
the
force
of
a
spring
that
is
attac
hed
b
et
w

the
plug
and
the
shackle
