DDD Burr Set (2021)

DDD Interlocking Burr Set is a collaborative effort between by Darryl Adams, Bryan Turner and Eric Fuller. This batch is the final release for the foreseeable future.

Darryl's inspiration came from Bill Cutler's complete summary of notchable pieces that can be used to form a burr shape. Bill's set of 42 pieces are sufficient to make all 314 solid notchable burrs and thousands of non-solid assemblies.

Darryl sought a smaller set that allows enough interesting combinations to guide the solver through increasingly difficult puzzles. He called it “DDD” for “Darryl’s Dense Dozen”. The set is “dense” in that it allows for 530 possible puzzle combinations; of those, 42 have a unique solution, and 24 are solid with no internal voids.

Brass pieces are precision machined by Bryan Turner and stored inside a Lacewood and Wenge box designed by Eric Fuller. The fit of both is sublime; assembled puzzles feel as though machine from a solid piece, and the box is so precisely crafted it seems to have no possible opening.

PDF directions for DDD Burr Set can be found here. The Burrtools file for the complete set can be found here. PuzzleMad has written a very fine blog review of this puzzle. Additional burr pieces can be ordered a la carte from Bryan.

Approximately 90 copies are available. Each puzzle is signed and dated.

Our work is handcrafted to very precise tolerances and must be kept within the range of 40-60% relative humidity at all times. Failure to do so may cause inoperability or permanent damage.

Please read the Caring for Wood Puzzles guide to ensure proper fit and operation. We recommend an occasional polishing with Renaissance Wax to keep wood puzzles in top condition.
