它是“ H”形毛刺吗？

改进的H毛刺又名H盒毛刺 拼图先生

大概一个月前 我看过了 one of Brian 您ng's 2012 限量版 the L burr! I started with that one because a friend had suggested that the way it interlocks 和 the rotations in it are very counterintuitive 和 difficult to find. I am also a sucker for contrasting woods so the L burr was the start of my journey 和 what a way to start!

现在，我要写一些关于旅程继续的信息-我一直在用这套节奏来做节奏，因为它们实在太多了，我真的 不想一劳永逸！我要尝试的下一个优点是改良的H毛刺，也可以称为H盒。

现在，在认识我的所有人面前，我对我说：

"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:

很多H-还有一些突出的地方

您 can see that there are 12 H shaped pieces all of which look remarkably similar but on closer examination it can be seen that the 不ches 和 cross-bars on them are all different. So having found the disassembly very easy it was time to put it back together - this part Brian claimed was much more interesting 和 he wasn't kidding!!

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.

您可能想知道我对这一系列巨大的难题做了什么？我把它们散布在书房的各处，有点等待被解决或整理掉或两者兼而有之：

这是一个狗屎坑！

Unfortunately, the present Mrs S decided that the shithole was out of control 和 I had better tidy it up. I was about to challenge her with the "or else you'll what?" that us boys can do when we are feeling particularly brave (or stupid) when I felt a flutter of fear 和 just meekly said "yes dear" 和 decided it was a chance for a reorganisation, to put my special 大 puzzles in a place of honour 和 maybe also make a little space for some more acquisitions:

限量版是“上架”难题！

As you can see above the computer on the top shelf are my 5 限量版 - beautiful! If they drop on the computer then it will be a dead Mac but it's nearly 6 years old 和 on its last legs so I'll 有 an excuse for something shiny to replace it.
