Thrustline Arapahoe C, Part 7, Fin Cutting and Fitting

To help prevent the wood from breaking down the grain, start the cut at the corner where chipping can occur.

Only one fin half had to be pieced together.
When piecing balsa together, sand the edges flat (get rid of the burnt laser cut edge and square up) before gluing together.

Here's the three fins, ready for gang sanding and rounding of the leading edge.








The root edge did take some fitting to follow the tail cone curve.
