The document describes the process of trimming a photoframe and cutting a backboard. It details using tools like a pedestal drill, sand paper, and jigsaw to smooth edges and cut wood. Safety practices are discussed, such as wearing protective gear and waiting for blades to fully stop. Help from the teacher was needed to refresh skills like proper use of the jigsaw. The process went well though it took some time, and safety concerns about using vibrating tools were addressed.

Trimming
the
second
photoframe
Today,
I
had
done
most
of
the
trimming
work
of
the
second
photoframe.
I
started
to
work
after
I
put
on
the
apron
to
keep
my
body
clean
from
dust
and
wore
hard
shoes
to
protect
my
feet
from
sharp
tools.
As
I
completed
the
first
step
of
trimming,
which
was
using
a
pedestal
drill,
I
trimmed
the
photoframe
with
a
sand
paper.
With
a
pedestal
drill,
I
removed
all
rough
surfaces
on
the
photoframe.
Therefore,
this
time,
I
used
a
sand
paper
to
make
the
surface
of
the
photoframe
smooth
(See
figure
1).
As
I
cut
it
using
a
coping
saw,
the
surface
was
very
rough.
I
should
remove
those
sharp
edges
then
began
working
with
a
pedestal
drill
because
this
was
more
effective
in
trimming.
Next,
I
used
a
disk
sander
to
trim
the
outside
of
the
phoroframe.
I
should
above
the
dangerous
zone
where
X
was
marked
(See
figure
2).
It
was
difficult
to
trim
because
the
photoframe
was
curved.
Figure
1:
The
photoframe
had
cured
surface
so
it
was
hard
to
remove
rough
edges
with
a
flat
head
file.
Therefore,
in
the
photograph,
I
was
using
a
sand
paper
on
the
sand
block
to
trim
the
photoframe.

Marking
and
Cutting
the
Backboard
As
I
completed
creating
two
photoframes
and
only
left
one
photoframe
to
make,
I
started
to
mark
a
backboard
on
pinewood.
It
took
long
time
to
mark
the
backboard
on
such
a
big
piece
of
wood.
After
marking,
I
used
a
machine
tool,
jigsaw
to
cut
it
(See
figure
2).
With
hand
tools,
such
as
handsaw
or
tenon
saw,
it
would
be
very
tiring
to
cut
the
800
x
500
backboard.
Before
using
a
jig
saw,
I
should
stick
the
wood
to
the
bench
with
two
clamps.
I
then
cut
it
with
a
jigsaw.
Jigsaw
was
a
very
powerful
machine
and
had
a
long
and
strong
blade.
So
I
should
be
careful
when
I
turned
it
one
and
when
I
turned
it
off.
I
should
wait
until
it
finally
stopped
working
unless
the
blade
will
pop

2. out.
I
pushed
the
jigsaw
hard
while
cutting
so
it
would
be
easier
to
follow
the
pencil
line
and
cut
neater.
Figure
2:
The
backboard
was
too
big
to
cut
with
hand
tool,
such
as
handsaw
or
tenon
saw.
Therefore,
in
the
image,
I
was
using
a
jigsaw
to
cut
the
backboard.

AOI
/
Learner
Profile
Today’s
process
was
related
to
Approaches
to
Learning.
I
learned
some
safety
rules
dealth
with
jigsaw:
First,
I
needed
to
push
it
down
while
it
was
working.
Second,
I
should
wait
until
the
blade
finally
stopped
moving
when
I
turn
off
the
machine.
With
the
regards
of
Learner
Profile,
I
was
a
communicator
during
the
workshop.
Although
I
used
a
jigsaw
before
in
grade
9,
I
forgot
how
to
work
with
it.
Even
I
was
scared
to
use
it
because
I
could
felt
the
vibration
jigsaw
made
while
it
working.
I
was
able
to
manage
this
difficulty
by
asking
for
teacher’s
help.
Teacher
showed
me
a
demonstration
of
using
a
jigsaw
and
also
he
informed
me
some
safety
rules
that
I
should
obey
when
working
with
a
jigsaw
-­‐
Emotion
/
Changes
to
Plan
Today’s
process
was
satisfying
for
me.
As
I
predicted
in
the
flow
chart,
this
trimming
process
took
long
time.
However,
it
took
much
shorter
to
make
the
edge
of
photoframe
smooth.
I
could
move
to
next
process
quicker.
In
addition,
I
was
a
bit
scared
to
use
gig
saw
because
of
its
great
vibration.
Therefore,
today’s
work
was
successful.
