Well, I was able to get some stuff done over the weekend
I picked up 3 sheets of 16g steel and started cutting and welding.
Here is the roof - I wish I were happier about it, but it'll turn out ok
This is the frame of the roof:
Here is the sheet on the frame (this is unfinished - I'm gong to set apart a day to weld the rest of this and a bunch more)
Here are the sides - they're cut oversize so I can get them fitted well, but they're clamped to the trailer to get them out of the way
I've got the skin for the doors cut as well, so most of the cutting is done. I just need to fit everything, weld it, and make it look good. Then I can mount the doors and roof. Then I'll start on the fenders. I REALLY want to get this thing out of the garage before the snow flies.
