6th:
Aligning the rear spar in preparation for attaching the root
ribs. |
6th:
Using two carpenter squares to set the 19-inch spacing between
the front and rear spar reference holes. This is much easier
than the method used for the right wing, which involved
computing the diagonal. |
6th: Left wing work goes much faster, now that I know that the
root rib attach angles have to be removed from the spar.
Here's the forward rib, ready to rivet, next to the drawing to
make sure we use the right rivet sizes and everything is
according to plan. |
7th: Riveting the aft root rib onto the root attach angle.
Layout is on the drawing to make sure we have the right
rivets. |
