Back in July, I mentioned that I’d picked up the Gakken Metal Legend dragon kit, but that I wasn’t going to build it right away. Well, in August I built it. Again, these kits consist of flat parts made from soft metal, probably tin. You can bend most of the pieces with your fingers, but sometimes you need the slot tool provided in the box. Most of the kits are for either dinosaurs or insects, and are in the 1,000-1,400 yen range ($10-$14 USD). Dragon was 2,400 yen. (I went back to the bookstore I bought this from, and most of their other kits are gone now. No indication that Gakken will come out with a second Metal Lord, but I hope they do.)
The booklet that comes with the kit has 6 pages of pictures and descriptions of dragons through history, from Europe, Japan and China.
The rest of the booklet has the assembly instructions, plus one page of suggestions for customizing the kit.
I didn’t count the number of pieces, but I’d guess it would come out pretty close to 50, not including the nuts and bolts. Most of the pieces were already fully punched out, but a few were connected together and needed to be separated. The metal is so soft that I could easily cut them with a small scissors, without damaging the scissors. I also didn’t keep track of exactly how long I spent on this kit. I’m pretty sure I worked on it for 2 hours one night, and then 2 more hours the following day. I did have some problems following the instructions (I didn’t try translating it from the Japanese) and ended up putting the head on upside down twice. When I got near to the end of the assembly, I apparently made a mistake in mounting the tail connection hinge (or, I was mistaken in thinking it was a mistake, and could have just swung the hinge piece out) and I then disassembled the entire body and removed the head to get to the hinge piece within the torso assembly. Regardless, I did take the body apart once, and disassembled the head 3 times.
The bolt mounting the head to the neck was just short enough as to make threading on the nut a real pain. That was the only place where I had to resort to using tweezers to hold the nut, and using pliers to squeeze the head assembly to be more narrow. The bolt has to thread through the outer head shell, the jaw, the tongue and the neck piece, which isn’t all that easy. Screwing up and having to do that a total of 4 times was not fun.
For the most part, making the sub-assemblies wasn’t difficult, just fiddly. But, it is important to fold the metal the correct way the first time. Folding, then refolding does stress the thinner metal bands, and risks causing them to snap. In fact, one of the leg pieces didn’t quite double over exactly right, with one side being a little higher than the other so that the bolt holes didn’t line up. When I tried correcting the fold, the little metal band between the two parts of the leg snapped on me. Fortunately, that piece was covered up by other sheet metal, and the break didn’t adversely affect anything. At the time, I was worried that I’d messed up the kit.
The hinge points attaching the wings, legs and tail to the main torso all consist of a metal pin that force-fits into a plastic grommet, so they are intended to pivot if so desired. The neck spine and tail are single strips of metal; you can bend them if you want, but they’re not actually hinged.
The box advertises that the dragon is 37 cm (14.5″) long. It’s a bit shorter than that if you curve the tail. Still, it’s the biggest kit in the Gakken metal series, and, it’s gotten me a lot of attention when I brought it to restaurants. It makes a great centerpiece in the middle of a table. Definitely worth buying and building if you like making stuff.
Because the box says that the Dragon is part of the “Metal Legend series,” I’m hoping a second large kit is going to come out at some point.

I was visiting family and we happened to be in Chippewa Falls. As we were driving around, I started yelling “stop, stop, stop!” Really, there was no particular reason for that, but when the car did stop, we found ourselves in front of the Club MTC Maker Space.
And, since it was there, I took photos of the Maker Gator in the parking lot.
I wish I had a maker space when I was a kid.
Or, now, here in Kagoshima…

These are the last of the square cycles. As mentioned before, there are 6 geometric solids, 6 hexagonal cycles, 4 square cycles, and the 1 twisted cycle. I’d already run the first square some weeks ago, so this is the last of the patterns.
The ring to the right is 4-step, and the other two rings are two-step cycles. They look good, but there’s not much to take pictures of.
Overall, the Kaleidocycle box set is worth the money if you get it at $10-$12 USD, and you like making papercrafts. There’s not much replay value, so after a little while you’ll probably just want to leave them on a shelf or give them away. The alignment of the patterns over the cut lines is off by an eighth to a sixteenth of an inch on every single sheet, which is annoying. You’d think that having 30 years from the original printing of the book that the publishers would have gotten that right. But still, if you like Escher, this box set is a good deal.

The remaining hexagonal cycles. In the set, there are 17 separate papercrafts – the 6 geometric solids, 6 hexagonal Kaleidocycles, 4 square cycles, and the one twisted cycle.
The one on the right has a 2-color map, so it repeats after two turns. The one on the left has 4 unique faces per double wedge, so it repeats after 4 turns.
These are the last two hexagonals, showing all four turns. The one on the left has 4 different patterns, the one on the right has only 2.

And now, the twisted cycle. This one is made up of 5 double wedges, and the folds are just off-center enough to introduce a self-occurring 180 degree twist. When you glue the ends together, it becomes obvious which way you need to turn the slot to get the full twist, because you’re going to have an optimist-optimist / pessimist-pessimist match up. In essence, you’re making a Mobius ring.
First tab glued.
The end of the finished fifth double wedge.
The cycle glued into a ring. There’s only the one twisted cycle in the box set. It’s no more difficult to construct than any of the other objects. It’s just takes longer, because of the extra fifth glue tab.
The finished cycle, after the glue cured. Visually, it doesn’t look as “clean” as the hexagonal and square cycles do, and it’s harder to see the animation as the ring is rotated through the center. To me, this is not a really successful experiment.
