I have changed the design of my rigid
Ramsay stacks. The new design is much more solid and much more elegant looking. It also allows me to make a bigger diameter hole in the center. I won't go into detail, because competitors swipe every hint they can off my site, but I no longer use pins to hold them together. The integrity of these new stacks is much greater than the pinned stacks. The stacks are normally made to look slightly askew on the outside.
