ASP Corporal Build, Part 4, Engine Mount and Fins

The instructions say the Kevlar should be 11 3/4" from the top of the engine mount to the tied loop. This would put the upper loop end right over the top of the body tube.
I made the Kevlar line shorter so there would be no chance of a zipper.
The engine mount is glued in the rear of the tube, both tube ends are even.

The fins are cut from 1/16" thick basswood.
Be sure to check the grain direction. These fins look like they should go the other way.

The leading and trailing edges are rounded.
Again, check the grain direction before rounding the edges. They are easy to get mixed up.
