Started laying out the parts for the cabin. Clamped PF-124 and PF-123 to the cabin base and drilled 3/16 holes. Put all the right side parts together and clecoed everything in place then drilled to 1/8. It fit perfectly as it is cnc predrilled. It is almost impossible to end up with a crooked cabin. I had to split my work table in order to have enough space to build the cabin.
