from mrpuzzle.com.au:The puzzle is to assemble the six differently shaped pieces into this very complex interlocking burr.

The Triple Crossed Burr looks great assembled. Unfortunately, this is the unassembled version. Despite Tom Lensch being ever gracious in sending me a duplicate copy of the paper assembly solution sequence, and my multiple inept attempts, I've been unable to reassemble the puzzle. A very nice display piece upon completion. Winning bidder to please e-mail for correct paypal address. Thank you.

Cubed Burr 2, designed by Tom Jolly (by adding bits to an existing Cutler burr) and made by Eric Fuller. The fit is somewhat tight on this, and there were only about a dozen made. It has 6 pieces and is a level 10, a few more moves than the Cutler version, but easier to assemble due to limited configurations available.. Fairly large and heavy at 3.75" per side. Weighs 1 lb. 6 oz.<p>Note that the wood is untreated. The picture also shows the puzzle halfway into the first move; it's actually...
