- sharpen the tip of a piece of 1mm carbon rod with 80 grit sandpaper.
- force it into the foam, run it all the way through. no glue necessary.
- add one at the control horn location and any other place necessary.
- use the piece like a needle. thread it all the way through, clip the rod, and you've still got a sharp point to do the next piece.
- Drill hole in 4mm carbon tube, make a crossbar with 1mm carbon rod. Threadwrap and CA.
- You want to make this an integral part of the wing, not just embedded into a slot.
- Make the slot with a modified soldering iron.
- Run a short bead of hot glue into the slot, press the CF into place.
- Hold flat with a steel ruler until cool.
- Open the joint, and repeat gluing until the full length of CF is attached.
- The forced-in CF tube will have caused a bend in the foam.
- Weigh the wing down on a dead flat surface.
- Run a bead of hot glue on top of the CF.
- Remelt the hot glue, making sure you glue the edges of the foam for maximum hold.
- Use a trim iron to remove any excess hot glue as you go along.
