Thanks for pointing out the true alignment of the central comb. I've modified the diagram to reflect your guidance. I must have been stuck in neutral on that one -- I've even created a couple of these with the foundation inserted at the 90Â° angle myself. :roll:
However, when the horizontal "Y" is pointing to the left on one side, it is pointing the opposite direction on the other side. In other words, when I am looking at side A the "Y" is pointing to the left and side B is pointing to the right, but if I turn it around so I am looking at side B, then the "Y" will now be pointing to the left also.
