Three new burr puzzles

We have started selling following three new puzzles, Stretchy 12, Staggered 12 and Juno's L7 Notchable.

Juno wanted to use one of our special plywood that can be used for 3 x 1 profile pieces. So, he designed Staggered 12 first and soon realized that he didn't have to use the plywood for the 3 x 1 profile pieces because their shape was not so complicated. If the pieces had enough thickness and they were made by hard and durable timber, the pieces won't break.

He has chosen Burmese Teak for Staggered 12 and started designing another puzzle that was good to be made by the plywood. Stretchy 12 became the candidate but Juno hesitated to use the design once because the puzzle must be way too difficult to solve even to very talented solvers. What changed his mind was the fun of the moves and transformation of the puzzle. Checking the solution on Burr Tools, he thought that it was going to be an attractive and gorgeous looking puzzle if three kinds of timber were used.

After he had finished making Staggered 12, there were several meters of Bubinga stocks. Juno made up his mind to use up those remaining timber and designed a rather simpler puzzle. It became Juno's L7 Notchable, a six piece burr that requires seven moves to remove the first piece apart from the assembled shape. As you can see in the image below, there are pins and holes on the pieces. This is how Juno cheated to make the puzzle a bit more complex compared to a normal notchable six piece burr.

We have been working on a sequential discovery puzzle now. It seems that we have to do lots of work to complete the puzzle. We can't say at this moment when the next puzzle will be released. We will release a newsletter when the puzzle becomes available.

Hope you enjoy our latest burr puzzle products.

Four puzzles to auction

This is our ninth puzzle auction and this time, we put two kinds, four test version puzzles up for auction on eBay.

Juno always prepares test timber stocks or extra pieces when he produces puzzle products. These test pieces are used for prototypes, settings for jigs and the CNC router, adjustments for numbers of parts and so on. In some cases, we lose these pieces during production, and in other cases, the pieces survive until the end of production and they can be used and called as a prototype or a test version. We are going to produce a product version of these two kinds of 12 piece burr puzzles very soon. Before we do so, we decided to put the test version up for auction and donate half of the sales amount to an animal shelter.

Stretchy 12
Sapwood of Bubinga is used for the 3 x 1 profile pieces unlike our original plywood for the product version. There are lots of grub holes on the surface of the timber, but we believe some people like such a character of the timber.

Staggered 12
Instead of Burmese Teak for the product version, cheaper Camphor Laurel timber is used for the 3 x 1 profile pieces.

There are two each of two kinds of puzzles on auction. To find out about more details of the puzzles, please check on the auction pages. We are looking forward to you joining our auction!

Doable 12

Doable 12 is our fourth orthogonal 12-piece burr puzzle product and it seems to be the easiest one among them. Although it's still a very difficult puzzle, Juno says that it's doable to solve without computer aids.

So, what are the feature of the puzzle? As you see the perimeter of the puzzle pieces, it has diagonal and curved lines. Juno has modified the shape of the pieces and restricted the puzzle to have not only a unique solution but also a unique assembly. You can trace which piece goes where in the assembled shape of the puzzle observing the shape of the pieces. Then the remaining challenge is to find out how and in which order the pieces have to be assembled. The burr puzzle requires 14 moves to remove the first piece from the assembled shape. It's tough but doable. (I mean to some serious puzzle solvers.)

Our originally made plywood laminated American Black Walnut and European Beech is used for the puzzle to increase the durability of the puzzle. The pieces have a very nice texture and a smooth surface. The shape is cut by one of our CNC routers and all the sharp corners are rounded using a router table.

It is very time consuming to produce those plywoods, but Juno has already produced a different profile of plywood and he has been working on the next project. Two more kinds of 12-piece burr will be released in the near future and I hope that you enjoy these puzzles.
