Real life has a way of changing plans...
Got all the spokes cut out on the wheels. Should have the wheels done in a few minutes. Got the fold lines fixed. The hitch cross-piece now is a laminated piece, instead of a box that glues over the front of the hitch. Should finish it up tonight and be able to post the final version.
Once this is all done I'll have to get it into the hands of the guy who has possession of the Coaching Inn and see if he'll take some photos
