Spent a couple of days laying out stuff on the panel.

After much back and forth, where I considered breakers, fuses (per Bob Knukols book) and even biting the bullet and ordering the vertical power unit, I ultimately decided to go with breakers. I talked with my avionics guy re. just using fuses and his advice was that there has been more than one instance where you get a fault on an avionics box and a hard reset cures it, so it would be nice if anything that contains a processor had a means to do a hard reset without cycling the entire avionics suite. After lots of careful measuring, I determined that there would be enough room on the panel for breakers if I packed them tight.

made a drill jig out of a piece of scrap with hole spacing 0.07" x 1.2" which accommodates the mini klixon breakers and went to town. This spacing results in 30 breakers on the panel, with barely enough room left over for the remote ELT switch way right above the longeron. I don't have a picture of it, but I cut that hole as well and it all fits.

I also laid out and cut the hole for the G5 on the right side. I don't have a chassis punch or a hole cutter that bid, so I used a fly cutter in a slow turning electric drill and kept it centered by backing it up through a hardwood block
