TLP Hawk Build, Part 8, Tunnel Shaping


After the card stock done was centered and glued to the nose cone, the card stock was stiffened with some CA glue wiped on with a Q-tip.

Here's the first application of CWF filler over the card stock cone seam and raised lip.
This was sanded down and a second coat of CWF was applied. After the filler dried it was sanded to surface.
EDIT: I should add, I sometimes do a wipe of CA glue after sanding down the CWF filler for a better hold on the surface.
Any remaining seams or dips were filled with a spray coat of filler/primer and sanding. 



Following the instruction booklet, a tunnel ends template was drawn.

After the curve ends were established, straight lines were drawn with the ends outside the tunnel sides. 
This allows me to set down the tunnel strip stock and set a single edge razor blade over the pencil lines. 


On the far left are the first straight angle cuts.
Next to that is the rounded off end, viewed from the back.
On the right is the rounded over tunnel top. 






After the CWF was sanded to surface,

all were taped down on cardboard for a spray of filler/primer.

  1. Just curious -- have you encountered any problems with adhesion of the CWF to the plastic of the nosecone?

    1. Hi Naoto,
      It stays on pretty well. Sometimes I do a wipe of CA glue after sanding it down.
