Description

I have decided to offer up this puzzle in an effort to further thin out my personal collection.

This is a clever design by Stewart that is nicely made by Henry, which was presented at IPP 25 in Helsinki, Finland marking his third participation in the Exchange.

Stewart wrote:

“Six polyomino pieces fit into a 3x3x3 box that has a cubic block attached to the top midpoint of one side, hence the name. It was presumed to have only one solution, but I was never sure until Bill Cutler confirmed it by computer.”

Shipping cost to be determined at close of auction.

Tube It In - William Strijbos by John Devost

It seems hard to believe that it's been almost 20 years since I first made a small run of this clever packing puzzle design in 2006. William has graciously allowed me to offer up another run as there were only a dozen copies made in 2006.The original metal version was William’s exchange puzzle at the IPP21 in Tokyo.This version is made using many wood varieties and includes a Stand. The entire puzzle has been ‘triple buffed’ giving it a very nice sheen.Overall size is a little over 4...

Pentablock - Stewart Coffin Design #2 by John Devost

I’ve been wanting to make this design for years and now after decades making puzzles finally made a copy using some of my Salvaged Piano Wood.One of the first puzzles that I purchased from Interlocking Puzzles (Wayne Daniel - RIP) in early 2000 was this familiar 12 Piece Pentomino design. I made a box to contain the 3x4x5 (3940 solutions) and the 2x5x6 (264 solutions) configuration.Everything has my ‘Triple Buff Finish’ and comes with printed solutions sheet.Shipping cost to be determin...

Four-Piece Serially Interlocking Cube & Modified 3-Piece version - Stewart Coffin Design #93 by John Devost

I’ve made so many of this design that I can’t even remember how many, it’s one of my favourites of Stewart’s designs. I often would make them when making a fresh batch of wood sticks for cube designs and when I last did that I mistakenly glued up a version that ended up being only 3 pieces instead of 4. I’m offering it up here as well as a correct 4 piece version both in Maple.Second photo shows the pieces of the 4 piece version.Both copies have been triple buffed as always and c...

This classic design was one of my earliest puzzle builds in the early 2000’s that I made for Bill Cutler.It features 18 pieces with four solutions, however finding one will definitely keep you busy for some time!I’ve always wanted to revisit it but in a smaller scale, I used a 3/16” unit size with the overall size being approximately 6” x 4”.The woods used were salvaged from an old upright piano from the 1920’s that I layed out the keys in a wall hanging (see last photo).
