Chapter 25 – Slowly dialing it in…

Last night I added a bit of micro/West 410 to the front and top inboard edge of the right rudder, and today I started off by knocking that down a bit before remounting the rudder. I then spent about 45 min. sanding the front edge of the rudder on both inboard (pic 1) and outboard (pic 2) sides to match the surface level of the winglet at the intersection between the two.  I may need some very minor tweaking after my final checks, but for the most part the right rudder is done.

With the leftover micro/West 410 in the cup from my inboard rudder added fill (and outboard right aileron edge too), I had filled a few key low spots on the wing as well as a bunch of egregious divots.  I spent about 15 minutes with a sanding block knocking all those back to level.

I then dove in on the right aileron, doing pretty much the same with it as I did the right rudder: matching the front and side edges surface level to that of the intersecting wing.

Again, I added some micro/West 410 to the outboard front and side edge, about 8-10″ of the top aileron, and then knocked off the rough stuff before re-installing the aileron.  Besides the outboard area that I added micro to, the remaining front edge of the aileron actually needed sanded down to match the wing surface level, so I taped the edge of the wing and hit the aileron’s front edge first with the orbital sander, then with a straight board (pic 1).  I then sanded down the added micro on the outboard side and leveled that with the surrounding wing surface (pic 2).  Also note the sanded down clickbond install that was also micro filled last night as well.

Here we have the matching surface levels of right aileron to wing, going clockwise from the top left pic, I started inboard near the first hinge and then moved outboard approximately a foot each position.  Not bad…

Although I need to work on the right strake, I chose to focus the rest of my time this evening on the left side since I had gotten the front half of the wing fairly dialed in with a nice smooth contour, but the aft side wasn’t cooperating as much.  The left wing seems to be requiring a bit more attention than the right wing.

After a few rounds of sanding mainly with the air file and 30″ boat board, I made a lot of progress, and tomorrow I’ll start back in with the long board.

I hit the left strake with a couple good rounds of sanding, doing the 45° sanding strokes once to the left, then once towards the right (standard op for all my flight surfaces).

I then spent about 20 minutes just focused on the left strake to wing intersection, mainly at the leading edge.  It still needs some final dialing in, but it’s pretty darn close at this point.

I grabbed these shots for both left (pardon the weird LED light patterns) and right sides.  The right wing is VERY close to being ready for epoxy wipes, while the left wing still needs a bit of work… I’d call it 70% finished at this point.  I also need to work both strakes as well, especially the inboard aft sides of those and their intersections with the top cowling front lip.

I didn’t grab a shot of it, but I whipped a small batch of micro/West 410 and did some filling on the left side, with my main targets being the BL 55.5 dip on the left wing (too low), as well as the wingtip just in front of the winglet leading edge (edge was low compared to wing).  Then, as I did on the right side, I used the remainder in my cup to fill a number of distinctly low spots and divots on both the left wing and strake.

Tomorrow I’ll continue to press forward on both right and left wings, winglets, and strakes.  One specific task I plan on completing on all surfaces is the blending of the bottom leading edge micro with the previous bottom filled surfaces.  I also plan on getting the left winglet squared away, to allow me to install the rudder and get it dialed in.

Pressing forward… slow, but persistent!
