I had to move things around, as has always been the case. This results in the back panel looking like this:
I've located every hole that I need to make, and will use a combination of my Sherline CNC and old skool layout with squares, rulers, and pointy scribes. This is the bottom. The front is very easy.
The odd part to this story is that I haven't actually drilled any holes yet. I've had a few distractions. Nothing bad, but one of my intents when I retired was to fish more. Between my rude introduction to gout in April and my emergency surgery in June, it was a very inactive year and we haven't had the boat out at all since I retired! We fixed that Monday by taking a few hours to go chasing the elusive fish, and then a few hours to clean up. You'll note that I said "chasing", not "catching". I've also had to adult a bit.
The next few days look good, though.
