Way back in 2011, when I was at a puzzle party here in the Bay Area, I had a play with a clever little puzzle, by Iwahiro called the ODD Puzzle. A simple three-piece packing puzzle, that was anything but simple. It's taken me three years, but I now have a copy of my own .... and I had to make it myself!
Back when I first saw the puzzle, the only copy available was a version by Philos. It was made from Beech and measured 4.7" x 4.7" x 3". The fairly plain appearance hid a superb puzzle, that was the grand prize winner at IPP28. Now it's mostly sold out everywhere you look, and no real indication of when or if it will be available again. The only place I've been able to find it is at Puzzle Sport in Germany.
I played around with the copy at Stan's and really liked the puzzle. It was clever and really needed you to spend time playing with the pieces in the box to understand just how they interacted with each other, and what movements are possible. I was unfortunate that the puzzle was sitting in its solved state when I picked it up, and it was more of a challenge to remove the pieces for me. If I'd not seen the solution I think I would have required a lot more time to understand how it would be possible to get the pieces in there. I had mostly forgotten about this puzzle which if I'm honest is rather a shame.
Fast forward three years, and I spotted a Craftsman copy of the puzzle made by Iwahiro on one of my friend's Facebook pages as his profile picture. (ed: There's a funny story there, but I'll come back to that.) Seeing that picture spurred me into hunting for a copy, and having failed, I asked a couple of my puzzle friends if anyone had a copy of the puzzle. Amusingly, the closest (geographically) to me had a copy of the puzzle, and agreed to lend it to me. A couple of days later, we met up and exchanged a few puzzles, had the obligatory play with a few new additions to each of our collections, and he left me with a copy of the ODD Puzzle, as well as a puzzle from his collection where a couple of glue joints had broken, that he asked me to fix for him.
Fairly quickly I took a host of measurements from the reference copy, and set about making a copy of my own. I really liked the look of the craftsman version with the 'core' having a different wood to the outer parts of the pieces so looking through my stock, I picked out some Lacewood and Yellowheart to make the pieces. Rather than describe the process in detail, the images below should show the highlights. (As ever, click for larger versions.)
Of course as you can see, when you're making one, it's not a lot more work to make two, or three, so I made three copies. When I was posting pictures, on my own Facebook pages during the build, I was contacted about buying copies, so I'm glad I made extra. One interesting build fact is that I pre-finished the bases before I glued up the boxes. The reason being that I was going to be unable to finish the inside of the base once the box was glued together. One benefit to pre-finishing is that the glue won't stick to the finish, so the base will be truly floating. I also pre-finished the inside walls of the box before I glued on the strips that create the gap. Again, I wasn't going to be able to get a brush inside the box to finish it to the level I wanted, so I finished it first, leaving clear areas where I was gluing up the pieces so that the glue would stick.
As a quick comparison, the pieces for both copies are identical in size, and can be interchanged between the boxes. In Iwahiro's version he has mitred joints in the box with slip feathers for strength. I used a shoulder joint on my box and didn't add splines (a.k.a. slip feathers). I did however change the way the top of the box is made, extending my slats all the way through the sides, making that joint stronger, unlike Iwahiro's version where the slats are entirely inside the box. There's not real difference, just a choice I made.
My the boxes in my copies are made from Katalox with a Chakte Viga base. I think the contrast between the dark, almost black sides with the bright orange base looks great, but then I wouldn't have done it if I hadn't.
This was the first time I'd used the Beall Wood Buff system since I bought it. Fellow puzzle maker John Devost uses it on most of the puzzles he makes, and having used it now, I can see why. The finish achieved is incredible. It's a high gloss shine, which really makes the wood look great, and gives it an amazingly smooth feel. It also means that the pieces in the ODD puzzle slide against each other with virtually no friction. That means that the slick plastic sheet added in the bottom of Iwahiro's version isn't needed in the copies I made.
One of my friends commented that the only thing missing from my copy was the slip feathers on Iwahiro's box. I joked that I'd considered adding Holly slip feathers, but in the end didn't do so. (Now I didn't mention at the time that I didn't have a jig built that would allow me to create slip feathers in a box) All I can say to that now is ...
They're not quite finished yet, (and I'll update this when they are) but I've added the slip feathers, purely for the aesthetic of them, and rather than have them flat, I put them at an angle just to add detail.
I mentioned earlier that there was a funny story related to me making the puzzles. As I mentioned, I was prompted to make these having seen the picture on a friend's Facebook. After posting pictures of the copy I'd made, the friend who had the picture sent me a message asking if I could send him measurements of the puzzle, so he could make his own. He didn't have a copy, and seeing me making my copies kicked him into deciding he should make his own copy, since he'd been meaning to do it for a while. So, I was prompted into making a copy having seen his photo, which prompted him ... Well it amused me at least!
This will be a rather short post, since it's not a puzzle review but rather one of my infrequent general ramblings. Many of you won't notice a lot of the work that goes into maintaining the blog as it's pretty mundane stuff like making sure WordPress is up to date, and the latest security fixes are applied. All rather dull, and uninteresting for most of you.
Recently I've been making a number of updates which you may not have noticed, but I hope will become useful. Quite a few people have asked if I allow people to register with the blog, allowing them to get notifications of new posts, and to possibly allow access to some subscriber only content. Up till now, I've not really had anything like that, but there are a few pages lurking around that you don't see, and I have kept for my own info, like a Puzzleography of the puzzles I've made, details about the number of copies, woods used, who bought them and the like.
So in the last few days, I've finished adding all the pieces of the puzzle to allow you to register with Puzzling Parts, and login. Once you do, you'll see a couple of new menu items will pop up along that top bar. And one of those is the records I've been keeping about the puzzles I make. It's still a little bit of a work in progress as I clean things up, but you might find it interesting.
As always, feel free to leave me comments and suggestions below. I do try to respond to everyone that gets in touch.
Oskar van Deventer has been at it again, and this is the latest (well latest published as far as I know) design from the incredible puzzle generating mind of the Dutchman. This time it's an intersection of six pentagonal sticks to form a pyramidal shape. The goal is to take the sticks apart, and put them back together again.
3D printed by Shapeways, the pieces are dyed into six bright colours (plus black and white) and have a solid feel to them. the trapped powder inside each stick really adds weight and a feeling of quality that can sometimes be lacking in Shapeways printed materials. The puzzle measures approximately 3.5" tall once assembled, with each stick being 3.5" long with a 7/8" cross-section.
The fit is perfect, and each of the sticks holds the others at the right angles all the way until the last two pieces. That certainly makes this a much more enjoyable puzzle to play with, as you don't feel like you're fighting your own fingers and wrestling with a dexterity challenge.
There's one key piece, followed by five notched sticks which must be removed in sequence to take the puzzle apart. While it's not trivial after the pieces are mixed up, I'd say that this is certainly an approachable puzzle for most people. Having taken it apart, and mixed the pieces, then left them alone for a while, I was able to put it back together in around 20 minutes. Now, I'm no expert in this style of assembly puzzle, but it was both fun and a good level of challenge for me.
Penta Beams is available from Oskar's Shapeways shop if you'd like a copy of your own.
I wasn't able to attend the IPP in Japan last year however given that I was getting married, I had a great excuse, and I'm not complaining about my choice of location. It did mean however that I missed out on a number of new puzzles from the IPP. Fortunately, I have a few friends who did go, and I was able to borrow some of the Japan Puzzles. Peppermint is a 3D printed puzzle designed by Scott Elliot for the Puzzle Exchange, and was digitally manufactured in colorful ABS by Bradley Rigdon at PrintTo3D according to Scott.
You can read all about the design process for the puzzle over on Scott's blog here if you're interested. I certainly recommend it as it really shows the work that goes into refining a puzzle design. The finished puzzle measures 2.25" x 1.75", and seems like a fairly large puzzle in your hands.
The puzzle consists of four pieces, which combine together into two linked sub assemblies. The outer shell doesn't move, while the sphere in the centre is free to rotate around. If you're familiar with the Cast Marble from Hanayama, then you'll have a fair idea of what's going on here. The difference is that you can only see the sphere from one side of the puzzle. On the other side is a closed dome that hides the sphere away.
Once you've found the right alignment of all the pieces, it will rotate apart smoothly, before coming apart into four separate pieces. Putting it back together is a simple case of reversing the process. there is a little bit of thought required to align the pieces correctly, but nothing that will stump you for long.
Overall it's a fun puzzle and it looks great in the vibrant colours of the ABS plastic. I'm seeing more and more puzzles being produced by 3D printers, and the quality is really impressive. For rapid prototyping, and the ability to play with designs just hours after they are conceived is incredible. I don't see it replacing the feel and look of natural wood, but I can't deny that it's an amazing technology.
Well that's a bit of a mouthful isn't it! 2 Halves is a burr puzzle designed by Gregory Benedetti, with my copy being made by the very talented Maurice Vigouroux. Back in November 2013, this came up for sale on Puzzle Paradise with a couple of options for woods used. Seeing the Ebony cage and Bloodwood pieces, I didn't hesitate, and bought it there and then. I certainly wasn't disappointed.
Despite not being particularly good with Burr puzzles, this doesn't look like a burr, and the jet black Ebony surrounding the deep red of the Bloodwood makes it look imposing. That's probably a good thing, as this is not a simple puzzle. It's not a small puzzle either. Each cubie is 7/16", making it 3" x 3" x 3" overall, meaning that Maurice was working with 1" thick stock to make the burr pieces. It's a great size and manipulating the pieces inside the frame is easy given the size of the pieces. It's heavy too. Ebony is a very dense heavy wood, so this puzzle has a really solid heft to it. The fit and finish are excellent with the Ebony being polished to a reflective shine. The pieces all slide past each other perfectly, and the tolerances are spot on.
The first night I spent around 40 minutes playing around with the puzzle and managed to create some space in the cage to move the burr pieces around a little, but I hit a dead-end and couldn't see a way to progress further. There seemed to be a huge amount of space in the puzzle, but the cage was still firmly held in place, and the was no way I was sliding any of the burr pieces out of the cage.
This carried on for a few days where I'd spend 20 minutes or so each night trying to make progress and really getting nowhere. As often happens, things got busy, and the puzzle was left on a shelf for a while with pieces sticking out of the sides, looking a little like a hedgehog. Recently I had a little free time, and picked this up again, since it was sitting looking at me and I felt bad that I'd not finished it.
After about an hour, I finally managed to shuffle the burr pieces into the right locations to be able to remove one half of the cage! Progress. It was quite the achievement to have made it this far, and spurred on by my success, I carried on to remove the rest of the pieces. I thought I was past the difficult part and the remainder was going to be easy. After all, I now had a lot of space, and removing the remaining pieces should be easy!
Isn't it great when you're totally wrong. The puzzle is a level 220.127.116.11.3 puzzle. So removing the first half of the cage, I'd only finished the first 17 steps. I had another 14 to remove the first burr piece, and then another 9 to remove the second. This is one tough puzzle. I spent another 15 minutes figuring out how to move the pieces around and take that first burr piece out of the remaining cage half, but I finally got there. Let's just say I didn't do it in just 14 moves!
As far as value for money goes, this has been a great puzzle. I've had a lot of puzzling time out of it, and I have to admit that I really enjoyed it. This is a little worrying for me, as I've never really found much fun in playing with Burr's. Maybe I've found something else that I do enjoy after all.
The 2 Halves is certainly a different style of Burr, with the cage interacting with the burr pieces in such a way that it really adds an extra challenge. The cage itself blocks your view of the voids in the burr, making it much more difficult to see how to progress, and it also adds some structure, keeping the pieces in the right locations without needing an extra hand to prevent them from falling or rotating into a position which makes it difficult to move the next piece.
Now, I freely admit that I'm not good enough with burr's to be able to re-assemble this one on my own. It was enough of a challenge to just take it apart. Not to mention that I didn't pay any attention to how the pieces came out, or the order, so I didn't even have a reference to how to put them back.
There's only one possible assembly out of 1,844 possible orientations of the pieces in the final shape, so it could take a very long time to put this back together with trial and error. I know when I'm beaten, and turned to the trusty Burr Tools to help. Even there it took me three attempts to get the pieces entered correctly for Burr Tools to be able to solve the puzzle. I have no idea how Gregory designed this, but I have to take my hat off to him. It's a great design, and I can't recommend it enough, even if you're like me, and are not a fan of Burr's normally.
