George represents those members of this forum that will accept nothing but the highest standards. Having been his student, I can vouch for that from personal experience.
So, although there is certainly some merit in presenting new ideas here, even if they need a lot more work, there is also something to be said for not presenting things prematurely. And I think that is what happened here. I will be the first to acknowledge that getting these joints just right is a very troublesome affair, and probably ultimately only possible with a jig for a mill or a radial arm saw or something similar. But George does have a point, and I think Will should try again, and this time with less focus on the novelty and concept, and a little more focus on the execution and final result.
On the subject of leaving chucking points on finished items: As far as I am concerned that is an absolute no-can-do. There is always a way you can remount a finished piece, which completely removes the need to leave a chucking point. And unless you are total wizard in shape, it always looks ugly.
