Leigh R9PLUS Joinery System and dovetail joints
This morning I opened my email to find the latest Fine Woodworking newsletter and in it one item caught my attention, the new Leigh R9plus joinery system. Being always skeptical (sceptical) of manufacturer's brochures/websites, I am very interested in the experiences anyone has had with this system, and how it compares with other dovetail jigs including such models at the Katie jig, and the more traditional jigs.
Another question: what is the optimal angle for dovetail/box joints? My admittedly very limited experience (Saturday Afternoon hobbyist) suggests that a great shortcoming of box joints is that they are held together only by friction, but the greatest angle, 14°, has the weakness that the endgrain is subject to breaking loose because the widest part is held only by the internal cellulose strand hydrogen bonds and are not connected in any other way to the rest of the board. My own thoughts right now is the narrowest angle, 7° or 8° is probably the strongest.
