Nevertheless the cube permutes the classic way!For E and V cubelets, I came to the same conclusion of gfixler and Orri, due to the permutations. -Cut with the router. -Push board as far into the jig as it would go You need 27, but I bought about 40 to allow for some defects and to have some for testing.The Magnets: I would make interesting designs such as sea scenes with fish stickers and plastic plants from craft stores, as well as sand. This may sound technical, but it really isnt. I found K&J magnetics through Google:http://www.kjmagnetics.com/They have a huge selection, and I settled on their D32 3/16" disc magnets, which are 3/16" tall.http://www.kjmagnetics.com/proddetail.asp?prod=D32I got a pack of 100, and a pack of 25. Inverse square law works like this:invert the fraction that the current distance is of the original distance and then multiply it by itself. These were mounted on a base board, but in between was a layer of 1/8" thick wood (I used some of the maple, since I had extra) with a gap for the board that needed to be cut. :-D, GREAT JOB!!! I could not clamp it directly, but often I would push it deeper into the jig with another strip from behind, and clamp that in place.
