Semroc V2 Build, Part 4, Fin Shaping and Servos



A flat diamond file was used to do a final squaring up to the sand line.










After all four fins were shaped, the remaining
black ink is sanded off.
The X-Kit supplies the narrow fin servos laser cut on the balsa fin sheet. These are small and would be difficult to fill.

When this model was initially worked on, I cut some servos out of basswood. Look close - At that time I laminated some 1/16" basswood to get them to the correct height.
More before and after pictures:

On the left is the squared servo profile.
In the middle the ends have been rounded.
On the right the top and taper to the rear have been rounded.

  1. Did you do the shaping of the servos with the sanding block? I always have a tough time shaping tiny bits with a sanding block.

    1. Hi Daniel,
      I do the rough shaping with the block and smooth sanding (final rounding) with some 400 grit held with fingers.
