Task: Canopy Roll Bar
Today we continued work on the canopy roll bar. The upper
strap was drilled to the aft frame after measuring and marking
for each rivet hole. It's a long process but worked well!
Here the upper strap has been drilled to the frame. All holes
start as #40 and will eventually be opened up to #30 for AD4
Both straps drilled to the frame.
Next I cut 8 pieces of 1" X 3" trim wood and then
cut 8 slices of 1" wide by 3" long x 3/8" thick
balsa wood. With the balsa on top of the 1" piece, it
forms the 1 3/8" spacer needed to achieve the 1.5"
roll bar width.
Once the wood was in place, I clamped the top half of the
frame down and locked it in place.
Once the top half of the fram was clamped down, I marked the
horizontal 0.25" line and then used a square to mark
the vertical rivet line.
