This morning the plan was to continue playing around with the box spar components to see if there is a way to squeeze solid rivets where the ribs attach to the box spar. At first glance, the way Van’s has one assemble the box spar does not lend itself to using solid rivets on the ribs.
That said, it got me to thinking about the order
which components get assembled … so thought I would see if I could come up with
a doable plan to allow for as many ribs as possible to be attached using solid
rivets. Placed some of the spar box components together loosely to get a feel
for how the parts fit together and the possibility of using solid rivets to
attach the stabilator’s ribs.

Much to my surprise, when entering the shop I
discovered one of the garage door springs decided to break. I first noticed the
safety cable dangling. Then I saw the pulley the spring attaches to hanging along
with a chunk of the spring. Somehow the safety cable came out of the spring.
Further investigation resulted in the discovery of a major infrastructure
problem and the reason the safety cable came out of the spring. The wood attachment
for the spring and safety wire literally disintegrated. Glad I was not around
when it all self destructed.
Fortunately, none of the shrapnel damaged any of the RV-12’s components.
Looks like I have a little carpentry work ahead before continuing on the
The wood pieces the garage door spring and
safety cable attaches to is now a mass of splinters.
Suppose it would be prudent to just replace all
the springs for the two garage doors. Had one of the springs for the other
garage door broke, it could have damaged some of the RV-12’s parts. Soon the
garage will be storing large and expensive to replace completed assemblies so feel
it’s advisable to just replace all of the springs now.
