Continued work on the cowlings: 1. Fabricated aluminum space-filler tabs for both sides of the cowl. These will fill the gaps aft of the aft-most Skybolt tabs. 2. Placed and marked the Skybolt tabs on the right side. 3. Removed the tabs, then spaced, marked and drilled the pilot holes in the cowl for the tabs. 4. Re-clamped the tabs, then used the cowl holes as drill guides to drill and cleco the tabs in place. 5. Up-sized the holes to #30 size. 6. Marked the backsides of the tabs for where the 1/4" lightening holes will go. 7. Removed the tabs, then deburred them, trimmed them, and drilled the lightening holes. 8. Countersunk the cowl holes. 9. Clecoed the tabs in place, then riveted them to the cowl on both sides. 10. Removed the lower cowl. 11. Trimmed the lower edges of the inlets to the lines I marked yesterday. 12. Mixed up a batch of resin, flox and cabosil. Spread a bead of it on the lower junctions of the Skybolt tabs and put some more on the lightening holes. Smoothed the resin with my finger to get good coverage. 13. Filled the cleco holes on the front faces of the upper and lower cowls. (These were the holes I'd drilled to support the cowl on the fitment jig. 14. Used the remaining mixture to a). run a small bead along the lower edge of the firewall to help strengthen the lower cowl Skybolt tabs, and b). fill a couple of small voids on the inlet areas of the cowl.
