Main spar countersinking
With the impending move, I haven't had time to work on the plane. I spent a little time tonight countersinking the tank attach holes.
Some thoughts on this. On the left wing, I countersunk before attaching the nutplates and just used a block of aluminum on the back side to keep the CS from chattering. It was some work having to reposition the block for every hole.
This time I put the nutplates on first (as the plans suggest) and countersinking, the theory being the nutplate will act as a guide for the pilot on the CS. I'm not sure I like this method. The CS chatters like there is not tomorrow until just the very end. It doesn't leave a very nice hole when it's done. It is quite a bit faster than the other method.
TIP: Haven't had one in awhile.. but if you choose to rivet the nutplates on first here's what you should do. Set the CS to about 3/4 of a turn too turn shallow. Run the CS. Do this for a batch of holes. Then set the CS to the proper depth and go back and countersink the holes again. This method leaves a nicer hole.. smoother.
(Time: 1 hour)
