Adam, You are by no means alone. I had a kit of the Mini Super which would not go together untill I twigged onto the fact that the CNC cut parts were to a different scale than the plan. Contacted B. B. who suggested that I would have a lot of sanding to do!! Gave up but didnt give in and enlarged the plan on a copier where upon the parts then fitted. The wood quality was at the bottom of the cut so wont be buying another, which is a pity as there are some good old designs, its just the kitting which lets them down.
