Spade Case and two burr puzzles

It's been a while since the last time we have released puzzles.
We have started selling following three new puzzles!

Spade Case is the last one of our trump card series puzzle boxes. Each of three former puzzle boxes, Diamond Case, Club Case and Heart Case has a unique mechanism to open. Spade Case is not an exception. We believe that many puzzle box collectors would say, "I have never seen this kind of trick."

Grooved 6 Board Burr #1 requires 22 moves to take the first piece apart from the assembled shape. As you see on the image, there are several grooves on the surface of the puzzle pieces. The internal hidden pin travels along the grooves and this feature restricts the movement of the pieces. Sometimes when you disassemble the puzzle, you might think that the first piece almost comes apart. Then you notice that it is still on the half way of the disassembling process. The ends of each piece are reinforced by the darker timber Jarrah to gives strength and good contrast.

Tangled Clip Burr is a very solid and heavy 12-piece board burr puzzle. To produce very complex puzzle pieces with tough durability, Juno laminated three layers of thin timbers crossing the grains at a right angle. This is an extremely difficult puzzle and I think most human beings cannot assemble the puzzle without any clue or computer aids. Once the puzzle is assembled, it really stands out by the higher symmetry and colors of the laminated timbers.

Hope you will love our puzzles!

Our private jet

We bought a private jet in June. I know you are wondering how someone who runs a family business of puzzle making could buy such an expensive and luxurious airplane. What we really bought is a product of JET company; drum sander JET JWDS-1836. It costs one thousandth of a private jet.

We have started using Burmese Teak since we produced Quartet Box. The timber is a gorgeous material, but it dulls the edge of the blades of our machinery tools, like the table saw, jointer and thicknesser. To change the blades of machines requires extra time and it costs dozens of dollars for the tungsten carbide blades of the thicknesser. So, Juno wanted to do something for the issue.

In Australia, the end of June is a fiscal year-end. We have sold puzzles so-so this year and had money to spare to buy some new machinery. We thought we are going to need a drum sander in the future anyway and it might be a good idea to buy it now. Then we headed to our favorite shop, "Carbatec."

Juno has done several customizing operations to the drum sander that we bought. We knew that a genuine product of an in/out feed table is sold, but it is not designed as folding, so it takes room when it is not in use. Juno bought L-shaped foldable brackets and made the in/out feed table which can be folded when it is not in use.

The height of the conveyor belt of the JET JWDS-1836 drum sander can be adjusted. Therefore, if the height of the conveyor belt has changed, there can be a step between the conveyor belt and the in/out feed table. Juno added an adjustment function to the in/out feed table, and made both the in/out feed table and the conveyor belt to be able to be the same level.

When we make puzzles, we always pay attention to even under 0.1mm measurements. Even if Juno adjusts the drum sander very carefully, if the position where he put the timber through is different, the thickness of timber would be slightly varied. To avoid this issue, he made the T-shaped fence and made it adjustable to the in/out feed table. Letting timber go through along the fence, there would be almost no discrepancy of the thickness of the timber that comes out. Furthermore, the fence makes it easier to put through multiple timber butting their front and back ends to prevent snipe that usually occurs on both ends of the timber.

He also attached the DRO (digital read out) to the drum sander. The DRO is helpful for fine adjustment for the height of the sanding head.

When he changes the sanding belt, the simple stick helps to keep the top cover open. To fix the top cover in a closed position, the star nob can be used that was changed from the original screw. The star knob can be turned without using any tools and it is very convenient. These are using a little ingenuity, as each such customization contributes to increasing the efficiency of the work.

We are currently making three kinds of puzzles. The drum sander contributed significantly to produce those three puzzles. Our private jet cannot fly, we still love it very much.

We assume that we can start selling our one or two new puzzles in October.
We are working on them very hard almost every day.
Please wait a little more until our unique puzzles are released.

Five puzzles to auction

We have put five puzzles up for auction on eBay!
Every puzzle starts from $1.00 AUD!
Please have a look at the Pluredro eBay shop and join the auctions.

Meanders Box (2nd grade)
This is a 172 steps version of Meanders Box. As you see on the image, there is an obvious chipout on the grooved lid. There is also a hairline crack on one of the upper white rail piece. The puzzle has no problem to play with but we don't want sell the puzzle as our regular product.

3D Shuriken (test version)
Juno made the test version of 3D Shuriken using Utile timber before the production of the regular Burmese Teak version. The puzzle has a bit of a loose fitting compared to the regular version and sanding and arrising are also plain.

The following three miniature puzzles are made by Yukari, one of the owner of Pluredro Shop. Please also have a look at her blog entry about the miniature puzzle.

H Burr (made by Yukari)
The puzzle is made by Yukari. Solid Burmese Teak is used for the puzzle.

6 Board Burr #1 (made by Yukari)
Plywood of American Black Walnut and Koto is used for the puzzle. This classic puzzle designed in 1990 has a slanted checkout and the solution is a bit unusual.

6 Board Burr #2 (made by Yukari)
Plywood of Blackbean and Sliverash is used for the puzzle. The larger version of this puzzle was exchanged at the 16th International Puzzle Party held in Luxembourg in 1996.

The above puzzles, H Burr, 6 Board Burr #1 and 6 Board Burr #2 that I (Yukari) made are small but can be played with.

As serious cat lovers, we are going to donate half of the sold amount of this auction to The Animal Welfare League Queensland. They also support stranded dogs, houses and other small animals as well, so we also welcome all animal lovers to attend the auction.

3D Shuriken

We have released a very difficult interlocking burr puzzle, 3D Shuriken.

Shuriken is a kind of weapon also called a Ninja star. There are various types of shurikens that have symmetrical and flat shapes. Juno designed the puzzle preserving its highly symmetrical shape and he made it three dimensional, so he named the puzzle as 3D Shuriken.

It is a very difficult puzzle and Juno says that it is almost impossible for human beings to assemble the puzzle if the puzzle pieces are handed disassembled and you have no preliminary clue about the orientation of the pieces. There are a possible 297 assemblies to the puzzle but only one can be assembled in three-dimensional space.

The timber used for the puzzle is Burmese Teak sold as "second grade" because there are lots of knots on the surface and the grains are very woven. These kinds of timber are not popular for boat builders because they don't want knots, but we could avoid dead knots when we cut the pieces and also Juno really likes the character of the timber. We had a win-win situation with a Teak lumber dealer and happily bought this gorgeous and precious timber.

Juno made a test version of the puzzle during the production and we are planning to put it on eBay auction in early September. A few of my miniature puzzles would be put on auction as well, so if you buy something else together, the shipping cost of the miniature puzzle is free because the puzzle has almost no weight and it can be combined for shipping without extra charge.

If you would like to get and enjoy the puzzle very soon, yep, they are available at our online shop.

Meanders Box

We have started selling our new puzzle "Meanders Box."

After Juno finished making Heart Case, he started making Spade Case, but he soon realized the price of the puzzle will not be in the range of the other trump card series because of too much expected CNC work. There was no appropriate room to put spade mark on the box as well. He changed his initial plan and decided to continue making the puzzle as Meanders Box. (Please be assured, he has already been working on Spade Case.)

There are two types of Meanders Boxes. Both Meanders Boxes have very high level solutions and it requires 172 or 348 moves to fully disengage the grooved lid. The puzzle also has multiple challenges. By rotating or flipping the lid, there are four possible orientations and each orientation has a unique solution.

It is a very difficult puzzle indeed. Juno had no intention to remember the solution of the puzzle and decided to cheat by adding two screws on the bottom of the box to easily assemble or disassemble the box. If you are stranded in the same way as the meanders of a river, you can disassemble and reset the box.

Three kinds of timbers, Burmese Teak, Rose Alder and Silver Ash are used for the puzzle. Burmese Teak is beautiful and durable timber though it makes every woodworking blade dull very quickly. We decided to introduce a drum sander in our workshop to deal with the issue and the drum sander started working for the puzzle straight away. Maybe we can introduce our drum sander someday on this blog because Juno customized it a lot and you may be interested in what he has done for puzzle making jobs .

Mirii 6x4 - Polyhedral shape interlocking burr puzzle

We have started selling our new puzzle "Mirii 6x4."
This is our third version of the Mirii series polyhedral shape puzzle. This time, Juno has chosen six intersecting squares for the theme and has chosen all 15 possible shape pieces to be used for the 24 pieces burr puzzle.

The timbers which were used for Mirii 6x4 were PNG Rosewood, Koto and Jarrah from the left to the right on the image below. The edges of the pieces are all arrised. Even the insides of the checkouts are lightly sanded after the first coat.

The puzzle is very difficult but please be assured, we will provide you a very detailed step by step solution upon request. The solution will also tell you where to find good places to put rubber bands for temporary support to hold puzzle pieces.

During the production of the puzzle, Juno made a simple mistake for the quantity of the material and the number of the finished product doubled. He complained how many checkouts he had to make, how much sanding and arrising he had to be done. Yep, he is responsible to his mistake. We have more puzzles to sell than we planned but it is not yet a large quantity.

The puzzles on our online shop are all one-time productions and we won't make the same puzzles again. They are all limited products.
So, I believe that he won't make this puzzle in the future as well.

Happy puzzling everyone!

The 6th Auction Results

We held an eBay auction and it ended on 17th July.
This time, we had put 2 kinds of puzzles for 2 each, in total 4 puzzles.
One is "Mirii 6x4 pine version" and the other is "Mini 6 Board Burr #3."
The sales results are as follows:

Mirii 6x4 pine version #1 - AUD39.75
Mirii 6x4 pine version #2 - 44.00
Mini 6 Board Burr #3 - #1 - 26.00
Mini 6 Board Burr #3 - #2 - 26.00

The total amount was AUD135.75.

As we had promised, we went to the AWLQ (Animal Welfare League Queensland) and donated roughly half of the sales (AUD70.00) to support dogs and cats today. Here is the receipt of the donation.

We met some fluffy four-legged friends there. These are some pictures I took.

We live in the western hinterland of Gold Coast and don't go to Gold Coast often. So, we thought it's a good opportunity to go and see pelicans. There is a famous spot to see feeding pelicans in Gold Coast. These pelicans are all wild; the restaurant staff gives them fish offal at 13:30 every day and they know it and gather together.

Had a delicious lunch, saw pelicans and donated half of the sales of the auction, it was a lovely day.

We will soon sell the next puzzle.
Please look forward to it!

New Puzzle: Heart Case Released!

We have produced two kinds of trump card series puzzles; Diamond Case and Club Case, and it's time for the next puzzle, Heart Case.

Heart Case is literally a heart-shaped puzzle box. To me, it looks like a small heart-shaped cake that has chocolate coating on the top. The size is not so big, but there is a room which can contain a ring or a necklace.

This puzzle is not difficult to solve. once you have solved it, it's easy to open and close again. So, in a sense, I think this puzzle is practical, you can keep something inside.

I personally, like one with a geometrical shape on the mechanism inside of the puzzle. Oh, I want to say it, but I cannot! If you are interested in geometry, and you succeed to open the puzzle, you will know what I mean.

I think this puzzle can be used as a gift box when you give someone a gift, like a ring. The shape of this puzzle is good for gifting to someone you love.
Therefore, Juno and I made a special option.

There are small parts inside. One of them has a brand mark "Juno" as we always have done. However, if you are going to use the puzzle as a gift box, this name might cause misunderstanding, you know? The situation that we worried about is described on the four-panel comic as below.

The names in the comic have no meaning, I have just chosen them from my favorite movie "Batman."

Well, we have no intention to thwart your romance and cannot bear the responsibility even if you are jilted. So, if you want to use it as a gift box, please let us know when you order the puzzle. Maybe we can somehow help you.
