Estes DARC-1, #7307 Build Part 3, Prepping Part W

How do you fill the small holes in the balsa?
The hold down tics in the holes are sanded down with a small diamond file. Just remove what is left of the tics.

Sharpen a dowel and sand smooth.
Set the dowel in the holes and gently turn. This can compress the edges, round out the circle arc and sharpen the edges.




A Q-tip is dipped in some CWF filler.
Press into the holes and turn.

Before the filler dries, rotate the sharpened dowel again to lightly push the filler into the balsa.  
On the left - 
Leave the raised lip of filler until it dries.
Sand the filler flat, to surface with 400 grit on a block.

On the right I have applied CWF over the face. A knife blade cleared it from the laser cut lines.
Sand smooth. On this CWF application, keep the filler out of the holes.

You'll have to fill the edges after the piece is removed from the balsa sheet.
