PuzzleMad: Some You Win, Some You Lose!

In Fact, I Seem To Lose Most Often!

Kumiki Airlines - something not quite right here???

I do hope you are grateful? This will be my only weekend off work for 3 weeks and I am sitting still here writing a blog post for you...even when it is an absolutely gorgeous day outside! Mrs S is talking on the phone to the Mother-outlaw and I am trying to keep out of the way so that she might forget the chores she said I had to do! Whack! Ouch! Ooops - I guess she hasn't forgotten. I have been so busy at work and at home recently that I have barely managed to work on any puzzles at all and surprisingly not received anything new for a few weeks! My last little splurge was described here.

Today's story is about a little success and a whole lot of failure - I began with the Kumiki Airlines puzzle which I finally bought after several years of longing from Brian and Sue Young's MrPuzzle store. I had originally seen this years ago when Allard showed it off at an MPP and wrote about it on his blog back in December 2013.

The Puzzle was Brian's (assisted by the greatly missed late John Moores) exchange puzzle at the 2013 IPP in Japan. It was designed by the incredible Junichi Yananose and of course, made by Brian himself. The description and part of the spiel from Brian is that:

"The plane is incorrectly assembled and can’t possibly fly like this. You need to take the puzzle apart and reassemble it to make it more aerodynamic. To do that on reassembly you’ll have to solve the level 13.4 multiple move burr."

The base of the puzzle with instructions.
Not very helpful!

“Kumi ki” is a Japanese word that means “to assemble wood” or “put together wood”. Whilst I own a LOT of interlocking and burr puzzles, I don't own any traditional Kumiki puzzles at all. The use of the word burr in the title and description sort of filled me with hope. It would appear that this puzzle is primarily an assembly puzzle which I am usually terrible at but recently I have been having some success with assembly and was full of confidence...maybe too much confidence? This puzzle is made from Queensland Silver Ash and is a pretty decent size:

Wingspan: 140mm
Length from nose to tail: 160mm
Height of tail wing: 60mm

Brian rates this puzzle as 8/10 difficulty.

The first thing that sprung to mind to me was that it didn't look like it would fly in the form that was sent out and the first thing that sprung to Mrs S' mind was that it was "cute". I can live with that! Of course, I had forgotten the description which included the word "burr"! I only remembered the Kumiki word and only thought of the simple little plastic Kumiki puzzles I had played with as a kid. I couldn't resist and set to as soon as my photos had been taken. There are a couple of possible moves at first including a possible rotation which I tried to avoid. Within about 2 minutes with only 3 or 4 experimental moves, the puzzle split in half lengthways and crash-landed on the kitchen work surface before shooting in pieces all over the place! Well, that bit was easy!

Quite a few interesting but very similar parts and some unexpected 1/4 size cuts revealed

Having achieved the rather simple separation of the pieces, I immediately tried to reset the puzzle back to the beginning and was a little surprised to realise that I could not do it easily! I had to go and sit down at a table and work on it! The thing fell apart in 2 minutes flat and it took me about 15 minutes to reset! At least I was able to put it back to the beginning...the full solve was just a different orientation of the pieces - it couldn't possibly be that hard...could it???

Stupid boy! Brian's rating was absolutely correct - this is a difficult puzzle, at least for me. Initially, I set to attempting the proper aerodynamic assembly in the same way as the false start and of course, that was wrong. Put this down to lack of experience of Kumiki puzzles and me not being terribly bright! You might ask, "is this just a huge matter of trial and error until you find the correct burr piece positions and then assembly method? And...the answer to that is a most definite NO! I dare say that you might be able to do this by pure trial and error but that would be horrifically boring and definitely not in the spirit that was intended by either Juno or Brian. This puzzle has enough to be seen in the pieces that the assembly can actually be worked out by logic. I know! I can hear you muttering now that the fool is no good at logic and doesn't stand a chance! Damn those voices! I probably should see someone about them.

The puzzle had to be put down so I could cook our Sunday dinner and I left it at the incorrect assembly to ensure that I didn't lose any pieces to the cats who have a tendency to pick small pieces up and run off with them. After dinner, whilst drinking a nice glass of Sauvignon in front of the TV with Mrs S, I set to once more. I started with simple trial and error before gradually, over a couple of hours, I began to notice certain features of various pieces which gave clues for the start or end position and possible movements. This puzzle has a whole series of lovely Aha! moments during the solution process before one is left with an aeroplane that, let's face it, still won't fly but looks more plane-like than it arrived:

All I can say with this is AHA!

I simply ADORE THIS PUZZLE! It really is a Kumiki assembly puzzle and only has a very limited likeness to a burr. If you are not a burr person then you would still LOVE this challenge. It is very solvable and most definitely NOT one for trial and error. There is a real pathway of discovery during the exploration and eventual success that gives enormous satisfaction - every single piece and cut in the wood has been placed deliberately and paying attention to them will lead you toward success. I am sure that if you were desperate then you could model it in Burrtools but the presence of fractional height cuts make this a bugger to model. Buy it! It's not terribly expensive and you'll have an airplane on your shelf once it's done! By the way...Allard loved it too!

Having been filled with success, I decided to go straight to my other burr from Brian - the Mega Six burr (Craftsman edition):

I think it might look like this for a VERY long time (maybe forever)

Piston burr

Despite being a burr-lover, I only have 2 standard 6 piece burrs in my collection - the Piston burr made by the amazing Jerry McFarland and the Computer's choice unique 10, also made by Jerry but designed by the incredible Bill Cutler. I also have a number of very special burrs that look like standard six piece burrs in my collection but in reality, have rather unusual and special solutions which are a lovely challenge and then I have 3 burr sets (you will see these in a photo at the end of my post) which provide many hundreds (or thousands) of burr assembly challenges. I am simply rubbish at burr assemblies. I thought a while ago that if I start at the simpler level 1 challenges and move up gradually then I would start to get better...I was wrong, I am still rubbish! Quite a few years ago Nigel had told me in words of one syllable that the Mega six puzzle is fantastic and that I MUST get it. I used my recent splurge as an excuse to get a hold of a copy. If you aren't bothered about the gorgeous wood then Brian also has a version in a standard wood for less moolah. I, of course, bought the version made from Queensland Blackbean because I'm a sucker for gorgeous wood!

It arrives in a ziplock bag in pieces - make a straightforward 6 piece burr - simples! Yeah! right! Sob! Here's what Brian wrote about it:

"This puzzle really does show a case of 'don't judge a book by it's cover'. It may look like other six piece burrs on the outside but it is DEFINITELY not. The puzzle is incredibly more complicated than the commonly known six piece puzzle.

Bill Cutler first used a computer program to analyse six piece burrs in 1974 but it took until 1990 to analyse all possible six piece burr combinations. Mega Six is the result of that search for the maximum number of moves for a six piece burr with a unique solution. This does not mean it has a unique assembly, due to the number of internal voids. In theory the pieces should fit together in 20 different ways however, the reality is that you can physically only put the puzzle together in one of the 20 assemblies.

Mr Puzzle’s version, designed with Bill’s help, has one extra cube removed to increase the number of false assemblies.... As if the original Computer’s Choice Unique-10 was not difficult enough!

Not only OUR hardest six piece burr but THE hardest six piece burr!"

OMG! Let's just say that I have been working on this on and off ever since I finished the Kumiki Airlines and have so far made no headway at all! I'll keep at it but may get sidetracked by other toys along the way! This one I have definitely not won - I won't say lost yet but it might be years! Thanks, Nigel!

I also lost a fight! "She who threatens unspeakable injury upon my person" got very very fed up with the state of my desk in my study! I did say that she never has to go in there herself but that only gained me a Whack! Ouch! and a Laser burning stare - yeeeouch! I took a photo of the desk - what do you think?

It's not that bad, is it?

Whilst I had some annual leave 2 weeks ago she frogmarched me upstairs and pointed out my almost empty new cabinets and said that if I didn't make use of them within a day or so then she would put her own stuff in them! I was galvanised into immediate action and decided that the new display cabinets would house some of my most gorgeous and precious puzzles. I haven't really organised everything by craftsman or by type, although my main study is sort of grouped by craftsman as well as by material. The new cabinets look like this:

My precioussss - Can you work out what they are or who made them?

It's only the beginning but I would appear to have plenty of space for new toys! The desk and the rest of the study looks great and I have even managed to take a load out of the dining room and living room. I now have an almost placated Mrs S... FLINCH!

Here are the changed parts of the study:
