New Way Blade Runner, Part 5, Fin Prep & Grain Fill



Like all laser cut fins,
these aren't cut straight down but in a narrow wedge.
It'd be like cutting out fins with a straightedge and the knife blade at a very slight angle.

Just be aware of which edges are a glue joint, like the root edge. A root edge cut at an angle could glue onto the body tube at an angle.






The flat blades are glued onto an outside edge. I used a flat diamond file to easily square up the sides and inside corners. 







There are 20 pieces of balsa to fill!

When brushing on the thinned CWF filler, be sure to keep the tab slots clear and open. 
Here I'm using the backside of my knife to clear the slots.
