I have an X-Out Jigsaw in the mail, but I'm afraid it might not work for the layout I had in mind, but the picture you drew...typed... out looks like exactly like what I need, for the 10x4x20 layout I wanted to try.
If you can't get that ball to work out for you, let me know, and maybe we can make a straight trade. I can get pictures for you when the ball arrives if you're interested. Either way, Good Luck with yours!
