Task: Continued work on ribs!
finishing the right wing ribs today I started on the left
wing. I used my template to mark the location for the electrical
conduit in the ribs. I predrilled #40.
Then I opened up the conduit holes 3/4" with a Unibit.
I also used a unibit to drill the upper and lower tooling
holes to 3/8 for snap-bushings.
Here is a finished rib. Two 3/8" holes and a 7/16"
in the middle.
ALL of the ribs have electical conduit and bushing holes drilled
and deburred. Last thing to do is debur all the small and
inner edges with emery cloth tomorrow.
