Brief Description: Deburr, clean, and prime stab. top skin & Skeleton
1. Deburred all the holes on the skeleton (incl. the end ribs) and top skin. A flat file worked well on the spars and hinges. I used the dog-leg, speed driver with the rosebud deburring bit on the holes where there wasn't a flat surface amenable to the file. The rosebud worked very well, much better than the half inch drill bit I had been using, and the speed driver worked great.
2. Scoured the contact surfaces with 7047 ScotchBrite.
3. Vacuumed the interior of the assembly using a flexible brush to free Al particles from the dried 373 primer on the bottom skin.
4. Cleaned the contact surfaces with lacquer thinner on a paper towel. Rubber gloves kept the MEK from my skin. Rubber coated fabric gloves worked well, also.
5. Primed the contact surfaces with Cortec 373 primer and set up a fan to speed drying in the (now) cool garage.
