Rainer Nearly Killed Me...Again!

Popplock T14

T13 unsolved

Every few years, Rainer Popp lets loose on the world the latest edition of his incredible series of beasts. It had been almost 3 years since the T13 was released and I (as well as the rest of the eager puzzling fraternity) had begun to anticipate the next one. This does remind me that I have so far completely failed to do anything with that one and it has been sitting on my puzzle tray next to my armchair for over 2 years. In fact it has been responsible for a significant part of the weight of it and upset Mrs S by marking the carpet. I really should get a move on and start work on it again.

I guess that a few people get to hear early when the latest release is coming but I had absolutely no idea when it was due to be released. In fact this one has been released in phases already. At Peter Hajek's End of Year Puzzle Party there were a good few people who showed it off and several others piped up to say they had been working on it for a while (including Allard. Whilst I gulped at the knowledge of the cost of it (handmade puzzles from brass and steel are never going to be cheap) I fired off an email to make an enquiry and was duly put on the waiting list. A few weeks later a VERY heavy box arrived and the sheer beauty of the creation was revealed. It is 1.7Kg! I received the dire warning of a painful death if I were to crack a tile or the kitchen granite and I insisted that it would only stay in the kitchen for long enough to take my photos. It was very quickly taken into the living room to be a couple of weeks of evening puzzling. It isn't much fun having nearly 2Kg of brass on your thighs and it doesn't mix well with china mugs!

It has rivets and dials and a key and...no bloody keyway! That's very odd. Reassuringly, the underside has Rainer's mark:

The only thing possible at this stage is to poke at things and try to push and pull stuff. Needless to say, not a lot is possible. A few things can be twiddled but that's about it. I spent a couple of evenings twiddling and alternating that with prodding and can only say that by pure chance doing the same thing over and over again actually made something change. Wow! There's a first time for everything.

In my usual manner I backed up to the beginning and tried again. It didn't work this time. That's odd! I was sure that I hadn't hallucinated it. I tried it a few more times until suddenly it worked again and I had an idea what was required. I had no idea how it worked that way but I could do it repeatably. With my discovery, I had a piece separate from the main body of the lock. What on earth was I supposed to do with that? Time to look and think© again. After all these years, I am still rubbish at this thinking business. If you look close enough then there is something obvious to see at this point but fiddling with that obvious item doesn't seem to do anything. It's time again for random movements until something happens. Just because you cannot see it doesn't mean that nothing is happening or changing whilst you carry out random moves. Discovering my second item I could see what my random moves had done and why they had the desired effect. My second item is MUCH more useful straight away - YAY!

I had a keyhole at last but the key wouldn't go in it - there is a front and a back keyhole and they aren't aligned. Damn - he's a sneaky bugger!

And here I got stuck....for a very long time! By this stage I have a few pieces and none of them seem terribly useful even in combination. I suspect that this is the place where Allard spent a very long time as well. I spent over a week at this point with nothing I could even try. I did end up sneaking a little peak at the solution (these are nicely set out in stages to allow clues for just one step without revealing others). Interestingly, the step that was described was exactly what I had been trying to do for a week or more and not managed to make it happen. Did I have a defunct lock? Impossibly unlikely from Rainer but I fetched the device I had used all those years ago when I had locked up my Louvre puzzle:

It's amazing what you can do with an unfolded paperclip!

This amazing device showed me that the lock was fully functional and I put the lock back to the beginning again and put the unwanted tool away and started again. Even knowing what was needed and how it worked I still couldn't do it with the pieces of the lock. Why was that? Because I wasnt doing it right of course! It took another couple of days before I found the right technique and it's very very subtle. It requires the exact combination of moves and positioning to do the required thing but it works every time if done right - Phew!

Having done that elusive move, I'd like to say the rest was plain sailing but I can't. I am not terribly bright because I was only able to do the next couple of moves before getting stuck again.

I'm not going to give much away here but at this point the key is useful in several ways - mostly unexpected ways. The most important movement to be done is a bit of a shock when you do it. The clue to do it comes by a careful examination of the entire exterior of the puzzle and having a think©. At this point I was thinking the impossible or even the slightly unfeasible. I thought to myself

"Self, that cannot be possible!"

Of course, with Rainer, the impossible is actually quite likely. After a bit of wrestling I noticed a teeny tiny change and continued what I was doing and got the fright of my life! I had sort of understood that it was going to happen but when it did, it was quite a shock! The engineering in this thing is incredible! 

It was still not over! I had thought that the huge move might be it but there was still more to be done. The next steps were quite logical but nicely disguised and it took a few minutes to find out what was needed. Suddenly, I had an open lock and a breathless admiration for Mr Popp's ingenuity - this might be the best one yet!

There is absolutely nothing given away in this picture

I have taken a photo of all the pieces that I had at the end and it is breathtaking! This will definitely be in my top ten(ish) of 2025.

The reassembly is a perfectly logical sequence and only takes a couple of minutes. Now that I know the solution, the whole process (including the difficult step) can be done quickly and easily in no time at all. Every single time I do it I find myself with a very big grin on my face! Amazing!

Thank you Rainer - keep doing what you do, it is fabulous. I look forward to the T15 in a couple of years.
