Making the F-684 Gussets

I have been spending half an hour now and then in the shop the past week, but nothing worth posting. Today I finished the F-684 gussets, so I thought I better post a few photos..! 🙂

First I had to drill the holes, that bolt F-717 lower longerons to the firewall steel brackets.

I had to modify the forward ends of the longerons a bit to make them fit.

Both longerons drilled and temporary bolted!

Time to make the F-684 gussets.

Here they have been trimmed. The two flanges has to be bend a little bit to sit flush against the firewall steel bracket and angle. I just put them in my vice, and made the bends by hand. Took a few tries, but turned out nice.

Here I have marked the gussets holes, to check for edge distance.

Both flanges drilled. After that I repeated the whole procedure for the left side.

With both gussets done, I started preparing the F-902 bulkheads. First I enlarged the holes for the rudder cables.

First one deburred and fluted. No more time today…
