Semroc Aerobee-Hi KV-2 Build, Part 4, Fins - Again!

I thought the fin stock was too thick!
The face card pictures showed thinner fins and tunnels.

I didn't want to use the supplied fat fins and tunnels now.

I cut out some new fins and tunnels.
On the top is the old fin, below are the three new fins. The picture makes the new fins look larger, but they are the same size.

All edges except for the root edge were then rounded.

This time around I used a rat tail diamond file to form the low end and fit the rounded leading edge of the fins.
