To cut out the inside, a pilot hole was made...
...and tin snips used to remove the material. The hole was smoothed with a file and sandpaper.
The ridge was bent over a steel bar. A patterned tread will screw onto this piece as it sits on the top of the lower longeron.
The outside cut, filed and sanded.
Holes were drilled for the four mounting screws and the lacing.
Remember this machine?
The finished step.
This is where it will go.
Before the rain came, Ron and Brian wet sanded the fuselage and sprayed another coat of silver.
They also did some taping on the lower wing, and I added more tapes today.
