Then it was time for the Italian scrapers and jewelry   Moving  to  the  outside,  it  was  my  hope  to  remove  the
          tools to remove large areas of paint.                  fabric  skin  in  one  piece.  Boy  was  I  out  to  lunch.  What
                                                                 appeared  to  be  straightforward  turned  out  to  be  the
                                                                 Achilles heel of this part. The outside areas came off well
                                                                 but the buck stops there.

                                                                 Colette worked tools under the fabric but it too was like

                                                                 found that reinforcing tapes came off easy. Some areas
                                                                 of the fabric could be worked off by sliding tools under

                                                                 into the wood itself.



          Some of the tools of the trade; fine picks and scrapers and
           a few Dremel rotary tools. Removing the fittings, peeling
           the fabric and scraping the layers of paint and dope from
                    just one panel is a +50 hour process.
          I would like to throw a plug in for a little company in
          Calgary I use extensively for supplies called "Ken's
          Gems".  Ken provides supplies for the stone and
          jewelry makers, I could get lost in his little shop for
          days.  I have been using jewelry tools pretty much
          from the start.  The team now finds itself in there
          replacing worn tools.

          The inside of the panel provided some interesting
          features like carved initials, fasteners imbedded in the
          wood and mechanical damage to the wood where
          someone used a screwdriver to pry the panel from the
          fuselage.





                                                                  Only the outside surface of the panel is covered with fabric,
                                                                 but to finish it off, it is wrapped over to the inside by about an
                                                                       inch. Some of comes away easily; most does not.

                                                                 I tried ketone solvents both to soften and pull the fabric,
                                                                 with poor results. I then settled on sanding until the
                                                                 fabric was exposed. Next I used MEK (methy lethyl

                                                                 up scraping the surface to basically get a mud pile.
