Brief Description: Countersink holes on the spar (13-1)
I had a flat tire on landing in the RV-12, which damaged the wheel pant. So, I’ve spent much of my time trying to get that repaired and built back up and painted. In between some of the repair work I managed to knock out some of the countersinking for all the holes on spar. Some are just for the plate nuts (flush), but most are deep enough for the .032 skin dimple to fit. I targeted .007 deep for the countersink, per chapter 5 instructions. After countersinking all the holes, I came back with a q-tip and some wash primer for added protection. Now ready to start setting some plate nuts.
Made dimple gage for .032 skins (23-050)
Checking fit with dimple gage (23-051)
Flush countersinks for plate nuts and deeper countersinks for dimple (23-052)
