Smurf Extract

The fiberglass from yesterday was cured well, so I used the belt sander to trim the outer edge further.

Doesn’t it look nice now? Don’t look too close- it’s full of pinholes and other imperfections.

To fix those problems I mixed up a batch of superfil, aka smurf extract. To spread the filler evenly in the corner, I used another hotel key. These have turned out to be quite handy and useful for this kind of work.

While that cured I spent more time on the headrest structure. I found a good deal on a set of electrical knock-out punches on ebay, and it turns out that they make great lightening holes in aluminum. I sharpened the old tools on the belt sander and made a few test holes. These are some of my favorite new tools, because they are so simple to use and maintain, and because they make such nice holes.

Lightening Hole

This lightening hole took only a few minutes to make and debur.


While I was working on that Tabitha did more planning for the new window frames.
