Fabricating a panel for fuse blockTimer icon2.5h

Creating a panel for the fuse blocks.

I started with some wiring work where I put some initial wiring for the beacon and the elevator trim. The idea is to have two Deutsch DTM connectors that the beacon and the pitch trim will be attaching to.

I also drilled a hole through the vertical stabilizer and the fuselage for the tail light.

Then I worked on a panel that will hold fuse blocks. It attaches between the subpanel and the panel.

The location of the panel. I decided not to add any stiffening to it since I cannot really bend 1/16" thick material. I can always rivet an angle later, if needed (I could have also ordered sheet metal via OSH Cut, I suppose).

The panel marked for cutting. A bit of sloppy work, but doesn't matter.

The panel layout

Cut panel. One mistake I made is that I should have 3D-printed a template for drilling the holes to position them better.

And this is what the fabricated panel looks like. It should fit behind the screen. I will be watching for interference with switches, but I think I'm okay. In the worst case, I can use slightly shorter screws than AN515-8R8.
