Well, I haven't been accomplishing a whole lot this week. The snow is melting and it has been raining a bit, so things are pretty sloppy around here.
I did get the new axle mounted and it increased the track width from 58 inches to 89 inches, so it makes me feel much better about the stability. I also have been using machine screws to bolt 1"x1" strips of pine/spruce in the interior of the walls to have something to attach my 5/16" knotty cedar tongue & groove interior to.
I am starting to realize that one of the toughest phases of the project is just beginning. Surprisingly, it seems like that will be drilling the hundreds and hundreds of 3/16" holes for the machine screws and the pop rivets.
