Stewart Coffin's design #105. Used in the IPP-16 puzzle exchange.For such a seemingly simple puzzle, this one caused me a lot of problems to manufacture. There were originally supposed to be 40 made; only 14 turned out due to a couple of bad assumptions I made in the shop. Even so the price is somewhat discounted as the cuts are not as clean as I would have liked...due to the angles involved, I actually believe you have to have a saw that will tilt both right and left to make the cuts perfect. E...

Bart Buie has been making copies of Stewart Coffin's work for quite some time now as well as designing his own puzzles. His quality and craftsmanship is outstanding. Sadly he is not able to make puzzles full-time, so offerings from him can be very rare. Bart and I live in the same town and speak frequently, so when I heard he has completed a new iteration of the Hectix design I offered to list them on my website for him. TriSticks is a version of the popular Hectix. According to Bart, Mr. Coffin...

The second puzzle available from new designer Duane J. Einfeld, this puzzle is difficult on many different levels. it is simultaneously an interlocking solid, with sequential assembly and dexterity thrown in the mix for fun. The solution is straightforward but difficult. This puzzles was entered in the IPP26 Design competition.

Anodized Aluminum Burr PuzzleThis Aluminum burr contains no makers mark but I ponder if it may have been crafted by R.d. Rose. The only mark I do see on the puzzle is a number “006”. The puzzle is excellently crafted and slides very accurately with a good fit and a nice heft to it. The puzzle also includes a solution sheet but that too does not have any maker information. Shipping will be calculated at auction close, so please allow time for that before sending payment. Buyer is responsib...

RELEASED:4.21.2016PRODUCED:47 CopiesDESIGNER:Terry SmartCRAFTSMAN:Eric FullerMATERIAL:Purpleheart and YellowheartCOMMENTS:I'm a sucker for puzzles which take a common shape and do fun things with them. I especially like puzzles with cage constraints...they look good and can drastically increase complexity. Attis is a good example of that...by introducing a very simple cage, the solution of a straightforward burr becomes level 15.14.4. The contrast between the purpleheart and yellowheart makes it...

Construct the three-piece burr inside the frame 

Three pairs of different burr piece styles. 22 moves to completely assemble/disassemble.

A 6-piece 5x5x3 interlocking solid that requires you to remove 5 irregular shaped pieces from a central ring. For more details: http://archive.cubicdissection.com/html/ringlock.html

6-piece level 10 burr 

Six-piece level 18.2 burr. Like new. 

This level 13 six-piece plate burr is the result of computer analysis conducted by Bill Cutler. Cutler wrote: "A computer analysis of all 6-plate burrs was run over the winter of 2001-2002; the highest level found for removing the first piece is 13. The Chocolate Dip Burr is one of these assemblies - the only way to assemble the pieces so that the dark and light colors are separated is in this level-13 assembly.

Level 8.2 six-piece burr with a non-traditional final shape. 

A nice interlocking burr

The following is copied/pasted from Eric's original description (which can be found with his much better pictures here )"I've always like the Altekruse and its pic based variants...so when I stumbled across Brian's version, I was interested. Brian kindly gave permission for me to make a batch, so here they are. I'll let brian explan the rest to you (i.e. I'm stealing the description from his site). Some years ago Brian noticed a drawing of puzzle concept in Stewart Coffin's book The Puzzlin...

The puzzle has always been fairly loose, but otherwise in perfect condition. Please see 2nd photo for a better idea. 

Fit has always been a little on the loose side. 

Beautiful chuck-style burr - it took me ages to find move #2!Eric's description is at:http://archive.cubicdissection.com/html/crystal.html
