ASP Micro Hawk Build, Part 4, Tube Spiral Fill & Fin Marking




I still like to fill body tube seams, even on a model this small.

Two Q-Tips slid in the back end make a good handle when applying the CWF filler.

The nose cone had a slight lip, a little wider than the shoulder.
Sanding down the edge on the 3D print nose cone was easy.

Now it easily slips into the upper short body tube. It was glued in place using medium CA glue.
On this smaller diameter body tube, the tube marking guide fit perfectly! 

You re supplied with a small plastic angle to extend the pencil lines down the body tubes. Good thing ASP includes this tool, These tubes are too small in diameter to mark in a door frame.

  1. Did you say you make your tube-filling CWF slightly thicker than you make your balsa-grain-filling CWF?

    1. Hi Bob,
      At one time I did make the filler a bit thicker for body tube seam filling, but not anymore. It seems to work fine at the same thickness on fin grain and body tube seams.

  2. Hokay! For newer readers, that filler is 2.5 parts CWF to 1 part water by volume ... or if you've got a good small scale, 3.45 to 1 by weight.
