It might not look like it but, I've got quite a bit done this weekend. I finished the firewall and the long process of cleaning it up. I also cut the hole for the battery cable to pass through the firewall. I mounted the battery box and trimmed it down, still needs a slight adjustment, it's mostly done though. I also fabricated the aluminum fairings around the rear of the cockpit and mounted them, they also need minor tweaking. It's getting there, most of the jobs I had to do were tedious and time consuming, it's progressing though.
I totally failed in my effort to write up a proper tutorial on metal fab.

The short, take a lot of measurements, cut, measure again, bend it, hammer it, sand it done. I use a pair of hand seamers to continuously smooth the piece and also a body hammer. For rounded shapes just lightlt tap the metal around a rounded object with a body hammer and then sand out the kinks. You'll get it once you start.
I also use some aluminum angle in a vice to act as a sheet metal brake, it works quite well.
Here's the firewall with the battery box attached. Supports will be added to the front of the box later. Still need to clean up the flux around the box (black stuff).
I made it as thin as possible and sits above the bottom rail. The battery is actually mounted in there in this photo. You can just slightly see one battery wire running along the bottom, it'll be tucked in when connected.
The cockpit faring is seen in this photo.
The faux motor will be built over the battery box like this. Won't be too much longer before I start on it.
I might start selling these in kit form.
