Semroc MMX Blue Bird Zero Build, Part 4, Fins

With all the NARAM coverage I wanted to get back to the MMX Blue Bird Zero - sorry about the delays!


The fins are tiny and only 1/32" thick. Its good they are cut from basswood!

The instructions don't mention it, but I rounded the outside edges of the fins with 400 grit.


Basswood has very little grain so you can get by with filler/primer to fill the grain.

Here the fins are taped down to scrap cardboard. The root edges are butted against each other to keep the primer off.




Here's one large fin after sanding off the filler/primer. You can see the gray filler in the grain lines.

Note the root edge (to the right) has more of the filler/primer sanded off for better glue adhesion.
