Dad was back out on the project (weather was better today) and started on the GRT magnetometer mounting. After various options, rear deck, behind the baggage compartment were discounted, we went for the left hard wing tip. A quick CAD drawing and then drill and bend up.
The two vice + stock steel is working well as a bending brace.
The initial shape including a couple of nut plates.
Meanwhile I went back to the panel and in particular trying to work out a method for protecting the bottom of the breaks and hopefully providing some mounting real-estate for the fuse blocks.
This was the first option but didn't provide a wide enough base for the fuses.
With the basic profile sorted, I started on a full size .032 panel - takes time to get all the alignment right - the forward hinge is permanent, the rear hinge pin will be removable.
First looks with cleco clamps looks encouraging...
