Started drilling holes in the ribs to install conduit for running all the wiring throught the wing. First I made a template to mark the location for the hole on each rib. Bought 3 extensions for my step drill bits at HF. Started with 1/4 inch bit to start the hole then stepped up to the 3/4 bit. Even with the extensions the process is very slow marking the holes and step drilling. Actually its a pain in the A#%. I was able to drill and debur all the holes in the left wing.
