Rocketship Games Alice's Star Rocket #R6, Part 3, Balsa & Tube Seam Filling




The instructions are very will drawn.
Here you can see how the fins fit thru-the-wall and into the slots printed into the 3D engine mount.


The BT-5 tube had the seams filled with CWF.
On the left the tube top is squared up on a block with 320 grit sandpaper.

The inside ends of the tube were masked off to keep the filler/primer coat out.

The fins were separated from the balsa sheet.

On the right side - 
The six fins were taped down for a good shot of filler primer. 
Notice the root edges are butted against each other  to keep off the primer for stronger gluing.





I tested the fit of a MicroMaxx motor.
The engine mount needed a very slight adjustment for a better friction fit of the engine.
