Update: After countless hours and many days of work, the final wrap layers of
carbon fibre cloth have been applied. They are cooking as I type. I've learned
a few things and so far, it has been going well. I have to say that if the
spar ends up not fitting into the airplane, I have no idea what to do to make
it fit. I could not have been more careful.
I'm using foam panels and a thermostatically controlled heater to keep it at
about
25C for the cure. That worked well. The resin news to be 18C minimum to work.
I made a template for the location of the aileron bell crank hole and decided to
find the hole after each layup of 2 layers. I drilled it out each time. Thought
about probing with a needle and marking it, but it was easy to find through
2 layers.
Haven't measured the thickness yet. Should be able to attempt fitting it into
the
airplane about Monday.
This is a huge job, but it seems like each step is fairly straight forward. If
you are doing it, gather all the tips from all sources and then plunge in with
common sense. THANK YOU to Neville for his irreplaceable help!!!!
