Prepping for rib stitching. This shows chalk lines and reinforcing tape on each rib. Both wings ready to lace.
The stitching is not very hard to do once you understand the knots. It took me a couple of days. This pic shows the single knots under the fuel tank ready to trim off the ends. I used a small zip tie with the head cut off as a “needle”.
Rib stitching is complete. Next is to shrink the fabric the final time to 350 degrees with my calibrated iron.
Here is one of the drain hole grommets. Still need to melt the center out.
So this completes the covering process for the wings except for the wing tips. They still need to go into the paint booth for additional coats but I will wait until all of the other control surfaces are ready.
These are doilies I made for the drain holes that are located on the trailing edge between each cap strip.
Doilies were poly-brushed in place around the lift strut brackets, fuel caps, inspection rings, jury strut brackets and pitot tube.
The next step was to apply the finishing tapes to the cap strips, false ribs and the leading and trailing edge. Inspection rings were next.
After the rib stitching was completed the fabric was ironed to 350 degrees with the calibrated iron, and a coat of poly-brush applied.
It’s been several weeks since I have posted but the wings are coming along nicely. This pic shows the root end top and bottom fabric glued and trimmed. This i has been completed on both wings plus the wing tips.A Kitfox wing has a laminar flow, meaning the bottom surface is concave so to hold the fabric tight to the rib it must be glued and laced. More on this later. This pic shows the bottom of the wing, notice that the fabric is glued to the ribs.Here the fabric is being heat shrunk to 250 degrees.This shows the upper side shrunk to 250 degrees also. Next is to apply reinforcing tape to the ribs and do the lacing. After the rib lacing is complete the fabric will be heat shrunk to 350 degrees with my calibrated iron.This shows the front strut attachment…and the rear strut attachment. There will be doilies around these points and on other protrusions.This is just a simple way of testing the pitot tubeI opted to route the pitot tube behind the fuel tank rather than al the way to the tip of the wing and through the rear spare.This shows the left wing tip. Notice the aluminum strips bonded and riveted to the end cap strip. These are for attaching the fiberglass wing tips.
