Once the full size prototype is built and on the road, I can do real tuft testing.
I've finished making all the g-code files by the way. I'm almost out of foam sheets -- I need another 18 or so to finish all the cutting, too!
I'm doing more architectural work for pay this week, so I hope that the weather stays warm enough to keep gluing long enough to get the main chassis together.
Edit: I did manage to glue 6" onto the main chassis today. My brother's Tacoma is in the body shop getting it's frame repainted, so I'll have to wait until the weekend to buy the framing for the shelter, so I can then work in the rain.
