Today was an in-the-office day...first time in a while. But I did manage to beat the LA traffic coming home this afternoon, so I made it to the airport well before dark. I got a wild hair and decided to clean the hangar. I haven't done a thorough cleaning since before the wings went on, and the place has become an absolute dust disaster what with all the sanding I've had to do. Anyway, it's always interesting pulling the plane out of the hangar. It really hits you on both extremes -- one, wow, this is a plane I'm pulling out of the hangar; two, wow, look at that thing, it's nowhere near done. Lots left to do.

After the place was spotless (yeah, right) I worked on the wing tip lenses. As you may remember, this is the piece I used the Micro-Mesh kit on to sand off some overspray and then restore the clarity. Anyway, it's time to slice and dice.

First I drew a half-ass centerline for the initial split cut.

Another RV-7 builder described making the wing tip lenses as "doing two little canopies." I don't know if it's that bad, but the concepts are the same. Trim, fit, trim, fit, repeat. As with cutting the canopy, I used a die grinder and the thin cutting disc.

Bam. Two pieces.

Initial fitting...

First I trimmed off the flange, which has a very visible edge. I marked the next trim line to approximate the aft end.

Getting closer. Now I went with my usual masking tape cut-marking technique.

At this point it's very close. Within less than 1/8" all around. Just need to do a few minor tweaks and it'll be done. It's getting cold, and I'm bored of trimming already. Time to do something else...

Yeah, we've seen this before, huh?

A little while later I had the makings of an airbox plug. At this point I had just glopped on the Rage filler. The stuff sands so easily I'm just literally slathering it on to "skin" the foam. I'll sand this down tomorrow...too cold and I'm outta here (I apologize to those Minnesotans and northern Canadians who haven't seen positive temperatures in a while...everything's relative, right?).

Before leaving I took this shot of Frankenstein and Son of Frankenstein. The differences are that the new one has the filter rotated 90 degrees, it's shallower, and the friggin' outlet is way better oriented for the SCEET tubing bend.

As I mentioned, I'll finish this tomorrow. Hopefully I might even lay up the airbox tomorrow and be done with that (yeah, right).
