The Puzzling World of Polyhedral Dissections

Well that last burr seemed a little boring to me so I read up on them some more. It seems solid burrs are easier to make but they require less moves to put together and take apart. The hidden innards of the burr needs "holes" to get interesting lock like combinations which is what I find interesting. So I got to work and made one. This time I made it out of Mahogany instead of the basswood.



This bur is called Philippe Dubois' Burr. Clearly that is the dude that first figured out this crazy thing. My illustration might not show the best angles for all the moves to let you really get it. It is a very interesting puzzle with lots of sliding parts.

There is zero chance I could solve it without a guide to follow. These burr puzzles are scored by difficulty by how many moves are required to get each piece out. The solid burrs like my first burr are just 1 move. This one is 6 moves for the first piece and 4 more moves to get the second piece out! Then the other pieces come out easy. So this burr is scored as a 6.4 the highest possible burr is a 12. One problem with these high level burrs is if you put them together wrong you can never get them apart. Not sure why but I enjoy the thought of giving it to someone and that happening.

I'm pretty sure I am the only one that finds this interesting tho. lol [img]/images/graemlins/smile.gif[/img]

I used a beeswax finish I had from before. It is good for cutting boards and it worked nice for this also. Kept the natural look of the wood. This wax also smells like oranges which I thought was cool. Here is a close up pic of the blocks so you can see the finish. These are the "backs" of them as they are the parts that face "out" most of the time so I tried to line up the grain to look the best on those sides.





Here is a link to more info about this burr.

I am pretty happy with the way this one came out and will be giving it away for xmas. I am going to print out a little guide about it and how to solve it so the person can actually enjoy it.

I think I am hooked. lol

How did you find working with mahogany?

It's one of my favorite woods, and I find it to be reasonably easy to work with.

There is something about the grain of mahogany that I find very attractive, and it takes a light stain pretty well if you want it to.

You might also try playing around with fir flooring, although I don't know if you can find it in 1" thickness? Standard here is 3-3/4" W x 3/4", so if your design will work with that thickness, give it a shot.

Nice work....you must have lot's of patience, skill and love what you're doing!
