Task: Started the rudder today. I organized
all the parts and laid out the skins. I studied the drawings
for awhile to fully understand how the stiffeners are supposed
to be shaped. Van's does a great job with their punch machine.
They basically give you the dimensions and you simply have
to cut a straight line. It did take some sanding on the ScotchBrite
wheel to break all the edges and shape correctly. I didn't
have a lot of time today so only got the right side completed.
After taking the right side rudder skin out of the box today
I noticed some pretty deep scratches. I removed the acrylic
and could tell the scratches were through the alclad. I took
the skin over to Van's while picking up some extra rivets
and they decided it replace the skin for me. Thanks Van's!
are the stiffeners. They come in 8 long sections that must
be first cut in half.
I had to draw a cut line from the end to the pre-punched mark.
is another view of the large cut to be made on each stiffener.
is a stiffener that has been cut. It still needs to be sanded
All right side stiffeners cut
Here the stiffeners are laid out on the right
skin. You can see they must be trimmed with exception to the
bottom one. I used the finished edge on the last one to mark
the edge on each other stiffener to be cut.
2 Stiffeners completed!
