T-Slot Burr on sale

We have started selling our new puzzle "T-Slot Burr."

We haven't released rectilinear interlocking burr puzzles for a while maybe because our brand name, Pluredro (Esperanto), means polyhedron in English and Juno is eager to produce polyhedral shape puzzles. We also released a couple of puzzle boxes after the production of Visible Framed Burr, so maybe it is time to release another traditional burr puzzle.

T-Slot Burr is based on a cubicle grid, and by the restriction of the combination of t-slots and t-rails, each piece moves in a linear motion following X, Y and Z axis. I mentioned it as being "traditional", but the T-Slot Burr has a very characteristic assembled shape because of the external grooves on the pieces. Unlike some very talented puzzle solvers, for example, someone like Derek Bosch, most people cannot memorize the complicated three-dimensional shapes in their mind and move puzzle pieces around in the brain. So, Juno decided to make grooves not only on the inside of the puzzle pieces but also on the outside of the puzzle pieces to help visualize the structure of the puzzle. Now the assembled shape of the puzzles resembles an electric circuit, a neural network and so on.

T-Slot Burr has a unique level 18-8-1-1-3 solution. Juno designed a lower-level puzzle in his mind and arranged it and made it have more complex solutions using computer aid, especially by Burr Tools. It may not be difficult to disassemble the puzzle, but assembling the puzzle is very challenging.

Happy puzzling everyone!

We will soon start selling level 18-8-1-1-3 T-Slot Burr puzzle. During the production of the puzzle, we had a few puzzles that we were reluctant to sell at a fixed price because of some imperfections even though all of them were fully functional to play with. So, we decided to put those puzzles on auction. Here are the brief notes for the three puzzles below.

2nd grade #1
A part of the puzzle pieces are sapwood and the surface of the pieces is slightly rough compared to the normal version.

2nd grade #2
Juno made mistakes when he made a couple of drill holes for the screws and he needed to fill those holes using bamboo skewers. The total quality of this puzzle is better than #1.

Prototype
This prototype doesn't have any featured decoration grooves on the outer surface of the pieces. Quality of timber and finishing are not good as two of the 2nd grade ones.

As we have always done, we are going to donate a half of the sales of this auction. We used to donate to an animal shelter but this time we are going to donate for a wildlife cause.

In late January this year, we found a sulphur-crested cockatoo in the backyard and it looked very weak. It kept still on the ground.

Next day, we saw the same sulphur-crested cockatoo sitting just in front of the kitchen window and it looked like it could barely balance and stand on the lawn. So, we took him to the local vet and the vet said that wild animals can be treated by donations.

Therefore, we have decided to donate some money to the local vet for helping injured or sick wild animals. We will show you the result after we donate on this blog someday.

Ixia Box on sale!

We have released the new puzzle "Ixia Box" on our online shop!

If you have seen our previous secret box type puzzles: Diamond Case and Club Case, you may have expected Heart or Spade cases for the next. However, this time, Juno designed a puzzle on an Ixia flower motif. The Ixia has a beautiful shape of six-fold symmetry.

Ixia Box is more fit to be called a sequential discovery puzzle rather than a secret-opening puzzle box. Juno designed it so that you are able to see a hint for the next step while you are playing.

Ixia Box is made with lots of kind timber. The main body is made of Papua New Guinea Rosewood and Jarrah, the side decoration panel is Ebony, and the inner parts are Util and Bubinga (Sapwood). On the top of the box, there are two flowers, one is a two-coloured flower and another one is a three-coloured flower. The two-coloured flower is made with Jarrah (dark petals) and Koto (light colour petals), the three-coloured flower is made with Jarrah (slightly light colour of ordinary Jarrah), Koto (light colour petals) and Queensland Maple (brown).

This puzzle is made with not only timber but there are lots of metal parts inside. It also contains dense timber, so when you hold it, you will feel a substantial volume.

In the process of manufacturing the Ixia Box, the CNC router was hugely successful. There are several parts that couldn't be made accurately without using the CNC router such as the shape of an Ixia flower. To make one Ixia Box, it took about several hours running the CNC router. There was more production process which needed time; therefore, Juno started making the Ixia Box in December 2017 and it took about three months to finish it.

We are now very happy to finish making the Ixia Box and waiting for you enjoy it!
