I don't have any pictures, but I did drive down to the Mobile Dimension shop last Wednesday to check things out. The folks working there were very helpful and I had the chance to look at several mills in various stages of assembly. When I got there, they were demonstrating a gas mill they had just finished building and I was impressed with how well it cut. I think it had the 57hp motor instead of the 67hp and it still had plenty of power to plow through the log.
I'd really like to buy one of their electric mills (25hp main blade and 15hp edger) later this year if I can get 3 phase power here without breaking the bank. If not, I'll probably buy the gas version with the 67hp motor and build a roof over the mill with one or two sides closed in.
