Also started the roof section today ... aluminum sheet on top, with a Masonite headliner (which will have vents and a light of some kind). the "aft bulkhead" will just be 1/4" Masonite fromed with 1X2 pine and clad with aluminum... I'm down to just little bits &pieces of square tube now, and not keen on wasting a lot of time riveting that all together when it won't really be seen.
there will be an access panel of some kind in the back, and maybe a small hatch near the top for viewing ("he looks so natural") or even a webcam at some point.
The door is cut out and mocked up now... some serious problems cutting that out with a follow-bit on the Dremel... I may have to go with a wider gap so I can clean it up. That skin is just tacked in place now... I have to paint the inside, attach the plastic, then rivet the skin on... in place, I think... I really should complete the shell and make sure everything fits before doing that, because I'm already in a little trouble fitting the right side. I had to cut a little radius out of the top corner of the door so it would swing... good thing I thought of that beforehand- LOL!
Found some $20 sheepskins at Ikea...not bad at all... oh man, once I fit these to the seat with some Bungees, it's going to be one cushy "ride"... about 1/10th the cost of buying pre-made sheepskin seat covers.
Just had to lay 'em in there to check it out... mmmm... wooly.

Once I finish the shell, I'll remove all of it and get to finishing the interior structure...
Then it's time to add switches, wiring harness, etc.
And oh, yes, I guess i need to finish building the computer, and interface it somehow with this thing... almost forgot.

I'm currently building a website about the pit and some other stuff... stay tuned...
