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  

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.
