Step 6 INSTALLING HINGES ON THE LONGERONS

After cutting the hinges to length, I made myself a 4' long square by clamping together a large square and a 4' aluminum ruler.  I used the long square to align the hinges parallel to one another.  This image shows the square clamped to the instrument panel and also shows the packing tape I put on the hinges to prevent them from getting gummed up with epoxy.  I used a couple of stir sticks, cut on the ends, as stops to keep the hinges in the spots there were supposed to be.

Once the hinges were floxed on, I used blue masking tape to keep them from moving.  Now, time for some weight and another straight edge.
The long square I made kept them aligned in the longitudinal axis, in pitch I used a second straightedge and some weights to keep them aligned.  It took a while to set this all up but I wanted it to turn out right.
Once the flox was cured, I found a piece of wood that I could affix to both hinges and see how they worked.
Works great!  No binding at all!  Bring on the canopy!
No more work on Chapter 18 until after Chapter 17 finishes.
