Karleyman ,
At first the plans look a little daunting don't they!! The cabin area is outlined with the dowels as shown on the plans and the cabin door frame is brass tubing silver soldered together. All are hand fitted and it is more than a little tedious but it is how it is done. One piece at a time .
