1.3 Hours -
I had to go to work this morning, but I managed to find a little time to work on the plane before my girlfriend got home from her work. Therefore, I spent almost an hour and half countersinking the bottom side of the left spar. As with the top, I had to attach all the platenuts that will be used to attach the tanks. Then, countersink the screw hole using the platenut as a guide. The only difference from the top of the spar is that there are also 12 platenuts sites that need to be countersunk for a #6 screw…these will be used to attach three inspection covers. Since the countersinks for the #6 screws are much smaller than those for the #8s, I countersunk the holes prior to attaching the platenuts. Once all of the holes were countersunk, I applied some self-etching primer and called it a day.
Now I get to repeat the entire process on the right spar!
