From the resounding number of responses to my last project, it’s obvious to me that people must prefer puzzles to other types of my projects… so for all you hungry beavers,
thanks to a lack of the "obligatory" response acknowledgements, I have plenty of time to post another installment to the LBD Puzzle collection.
Years ago when I got sucked in by mtairymd’s Hexagon Puzzleon Lumberjocks, I also added plagiarism to my vocabulary.
I also realised that rabbet joint was really misspelt and should have been rabbit as those joints bred like bleeding rabbits.
Being a bit of a chicken-shit myself at LJ, I was intimidated by all the puzzle nay-sayers and grouped a swag of puzzles into one project, to minimise those delicate little precious's tranquillity… I’ve grown a set since, and have no fear of coping all the ensuing flack about individual puzzle postings.
I based my measurements on 25.4mm wide stock and using this 1:1, A4 template,
The thickness is immaterial (OK, in the material), however, the angles and dimensions have to be proportional in scale to the above diagram so that when two “modules” are combined, you get this shape,
Some chap by the name of Pythagoras proved that his serum, when translated from imperial,
will hold up equally well in metric,
though some of the measurements might be a tad hard to mark exactly... seems like both the imperial and metric angles are just about equivalent.
Using 4 pieces to make up a “number 7” and gluing 2 x 7 to give 14 (a piece),
with the 3 “modules” brought together
for assembly,
I didn’t have the resolve (and still don’t for this one) to try “carving” out of solids on my BS or scroll-saw and stuck to my MDF laminations…
though I could have laminated out of solids.
This turned out to be one of my most popular puzzles, however, it was a pain making full sizes of them just to donate to freeloaders. Went on the cheap side and started to make miniatures of them,
Even off the lazer, there may be alignment issues (due to dowels not being perfect in rated diameter) so I fudged assembly with the use of this small alignment jig,
nevertheless, some doctoring needed to be done which eventually proved to be an unacceptable overhead as the puzzle was too small to sand/buff for smooth operation. Consequently I rated the miniature puzzles in 3 categories,
Cat1 – Comes apart with the solution’s standard “twist”.
Cat2 - Comes apart with coaxing the solution “twist”… by the aid of a drop/bounce on a hard surface.
Cat3 – After assembly may, repeat may come apart with effort… would seem like CA was used. Many of these may not disassemble.
For those interested the SU model can be downloaded from the 3DW,
This puzzle was lumbered in with a swag of other puzzles in the following video that explains nothing… however, if you press “more” in the YouTube description there is a time entry to Otto fast track to this puzzle (or you can Manwell it to 7:18),
Don’t be crafty Craftisians,... SHARE your craft!

Must admit that I use the laser and a lot of MDF trees to make alignment jigs whenever I can... looks like I performed a few mortal sins by omitting similar in many of my past projects. Problem is that most are a 1 off and I toss them after the task as they kept building up and I never remembered what they were for... and when I write "the purpose" on it, I seldom remember "the method"... and you guys wonder why I write long crappy blogs and make videos... not for my audience, but for me if needed again in the future.
