Early fuselage layout
Grinding time today - Now that the upper longerons were steam bent, I needed to modify the OX-5 spider plate for the larger Hisso radiator. If you remember, I was fortunate to get a finished spider plate from Doc Hood. The OX-5 radiator was flat bottomed and rested on a lip at the bottom of the spider plate. The Hisso radiator is curved at the bottom (to provide more surface area and more cooling) and rests on a curved lip on the spider plate.
So, I had to grind off the straight lip in anticipation of welding on the new curved piece in its place.
Here's the spider plate without the lip.
The upper longerons were put back into the jig, measured and cut to fit into the spider plate.
Finished cut below.
Next step - bolt the spider plate onto the end of the table, attach the longerons and make the splice behind the cockpit. Stay tuned!
