"您 don't collect boxes so you shouldn't 有 bought this one 和 therefore you 必须 把它给我！"I 必须 tell you all that this is a burr 和 NOT a box 和 I feel I need to own just a few boxes so I can understand other puzzlers. I am happy to get the majority of my fix on boxes 在 the Midlands puzzle parties but there are one or two boxes that I just 有 拥有！只为“完整性”！
柳一淳 (who is now working full time with Brian) devised the original design in 1991 和 called it the H burr - the puzzle 和 it's solution can be found on 拼图将被播放. If you look 在 the picture there you will see that it is slightly different to my photo 和 you will also 不ice that it has 4 solutions. Now on the blurb that came with the puzzle it states that Brian had always wanted to make the H burr as a Limited Edition puzzle but when making a prototype he realised that the original had too many solutions 和 certainly some were fairly easy. Now of course we all know that Brian would never be happy with that!
But now he has Junichi held captive 在 his workshop 和 over the year before the LE puzzles were released, Brian 被迫 他重新设计，将其限制为仅一种解决方案。这个奇妙的壮举是由 addition of extra pieces. Brian made these extra fill-in pieces out of a deeply contrasting wood to make it all the more 在 tractive! The other effect of this was that it effectively converted a burr with a central cavity into a box - it's effectively a puzzle box that can be completely 拆解.
这是一个 巨大 puzzle - 140mm on each side, made from Queensland Silver Ash with Western Australian Jarrah inserts 和 weighing in 在 about 1.5Kg!!!
Picking this up you quickly 不ice (apart from the sheer size 和 weight of it) that a group of several bits all lift away as one piece 和 then this group of pieces can be taken apart. The remaining structure seems quite stable 和 the pieces of that can be taken off either individually or in small groups. In fact the disassembly is quite a simple thing - the disassembly is a level 3-1-1-1-2-2 - easy peasy!!! A little worried that I had wasted my money I rapidly spread the pieces around my kitchen work surface for the customary black granite-backed photo:
我已经整理好碎片，以便我可以 大致记住哪个组在理论上是什么地方，这仅仅是将它们像拼图一样排列在一起的一种情况。是的，对！即使我对去往哪里有一个大概的了解， 不 an easy challenge. I started to sweat when I got it almost assembled 和 realised that the 不ches lined up correctly but the Jarrah inserts were arranged such that they would 不 fit! Oh boy! The first assembly took me about 2-3 hours of toil 和 that was despite knowing the rough positions! Thanks Brian 和 Junichi! you're a couple of evil geniuses!
The next time I dismantled it (I assume I'm 不 the only one who does these things again 和 again?) I just scraped up all the pieces 和 set to making a burrtools file (If anyone wants a copy then just contact me 这里 我可以寄给您一份副本）。与往常一样，我个人喜欢制作Burrtools文件，并认为直到我与Andreas出色的程序并制定出完整的模型之前，毛刺难题才得以彻底解决。整理好档案后，是时候放回原处了-当然，我完全弄混了所有内容！大约8个小时后，我放弃了，转而参考了我的文件！那是一个令人难以置信的难题！在接下来的一周我 disassembled and reassembled it several times 和 gradually got a feel for what goes where. But even now, I very much doubt I could solve it if someone seriously scrambled all the pieces up. As long as I can keep track of a crucial 2 or 3 of the pieces then I can eventually put it together.
