Haym showed me a working copy of this puzzle about 3 or 4 years ago and I just filed it away because I could quite see how I could produce it with my current equipment. Since adding CNC to the shop, this puzzle moved straight to the "Puzzles in Production" folder on my computer. It looks like you should just be able to make about 3 or 4 moves and remove all the pieces rather easily, but multiple obstructions make this more challenging than you would think.
I still have several copies in production if you find this sold out. They should be ready in about 2-3 weeks.
