Estes Vesta Intruder #7312 Build, Part 10, Fin Gluing

With the overlays centered I had a little overhang on the small trailing edge.

This was simply sanded off with 400 grit on a block.

Set the root edge next to the fin alignment line.

Mark just below the forward leading edge. You'll want to scrape off the filler/primer inside the root edge length.

To the right is a fin line scraped to the bare tube - 

just short of the root edge length.

The fin line will have to be redrawn after scraping. Use your aluminum angle to re-draw the line.

I rarely use the fin span drawing in the instructions but found it handy on this build.

I only glued on three fins to start. These are actually the three fins that get the faring side pieces glued beside them.

The top picture shows the gap at the root edge when the side fairing pieces are set next to a fin.

Here's a better fit after sanding a slight angle on the root edge of the fairing.
