I used a 3/4 in bending block and tapped the edges into place.
Then, the pieces are mated and brazed together.
Here's my friend David Daugherty taking his turn brazing.
Here are all the fittings for the lower part of the fuselage bent and ready to be brazed. The Universal fitting is used at every station from 6 to 10.
So, a total of 20 fittings need to be built.
Next shop day, I'll bend the fittings to fit the longeron.
While I had some time, I made the side brackets for Station 3. I cut the fittings out of .10 steel. Here is the evolution from plate to fitting. That's an original OX-5 fitting (cut off) on the left. The tubes bent in the previous blog will be welded to these brackets (so the Hisso will fit).
This will come together next time we meet.
