Dt process journal 3

  1. 1. DT  Process  Journal                   Jan  25th  2011      -­‐  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. 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.
