| Templates for the firewall surrounding
panels are traced on tracing paper. |
|
| The drawn template is cut out and tested
on the body, where it is suposed to fit. |
|
| Now the same profile is carried on the
metal and cut. |
|
| The metal panel is bent to profile by
hand and test-fitted. The same procedure is done for both sides. |
|
| The panels are point-soldered to the body
to secure in place. The main soldering will be done on the back side. |
|
| The back side is fully soldered. |
|
| The firewall is traced on paper and carried
on to metal and cut in the same manners described above. |
|
| After a couple of test-fittings and necessary
trimmings, the firewall is soldered into place. |
|
| Finishing is with Dremel again, but with
a metal grinding tip. You have to press against solder in this situation
and regular cutting tip will immediately break into pieces. You may use
a thick grinding tip, but the metal tip has a flexibility so that it will
not dive into metal if pressed excessively. So you can have a smoother
finish. |
|
| Here the parts are finished smooth. |
|
| The two internal panels that will fit
behind the door in the cockpit are prepared by paper-tracing and carrying
on the metal. The bends are made by pliers. |
|
| Solder was applied at the meeting edges
but the soldering iron proved to be weak for this area, so the solder was
melted along the seam with the aid of a torch. Parts should be held close
with some means as shown. |
|
| OOOPS ! The flame of the torch was
too heavy for the poor metal. You see how the metal shrinked? There are
two ways to repair the situation: Either fill more solder in the cavity
created, or leave it to the time of the polyester putty. I preferred the
second choice. |
|
| The two internal panels are now soldered
into place and ground smooth. |
