Fit, drill, deburr and cleco the F-704K Upright Cap Strips on the fuselage Center Section. The strips are very tight on the center section bulkhead. It took a very long time to properly align the cap strips. I finally had to use my painter heavy duty rubber gloves to be able to move the strips on the bulkhead. Otherwaise it was too slippery to get a good holdon the caps. Now have to rivet the strips to the center section aft and forward side bulkheads, using LP4-3 pop rivets.
