The Penultimate Burr Set is something I've wanted to make for a very long time. I love burr puzzles, and the versitility and value of burr sets is unmatched. This set of 27 numbered pieces combines to make hundreds of puzzles, from fairly simple solid assemblies to extremely difficult higher level assemblies. Never before offered in six unit length, a new analysis of the set was performed by Ken Irvine and revealed many problems which were unachievable with the traditional eight unit length pieces.
The box itself is quite special; the lid lifts off to reveal precise, ordered rows of burr sticks. What's missing are the instructions, hidden in a concealed compartment and protected by a puzzle box mechanism. You must solve the puzzle box before beginning work on the burr sets. This puzzle offers hundreds of hours of puzzling value!
This is some of our best work. The burrs are accurate and uniform, the box lid fits with precision, displacing air as you open or close it. The puzzle mechanism is tricky and completely concealed. Once discovered it's easly repeatable. I'm very happy with how these turned out.
