There comes a time when using small tabs can just get in the way of having clean, crisp and accurate corner joints. This is especially true when the parts become very small and difficult to work. I have solved this problem in certain situations by just simply cutting them off and using an armature to support the part. This works well for butresses, plinths and other parts where accuracy is of paramount importance. The first shot below shows a typical part that is intended to be folded up into a small cube. The second shot shows a strip of MDF cut to size with the cube glued to its plane surfaces. The length of the strip allows the part to be cut off easily after the part is glued. The process is easy and very accurate. J.L.
