Grooved 6 Board Burr #4

SKU: P10058

We have produced Grooved 6 Board Burr #1, #2 and #3 in the past and #4 is the hybrid version of the former three designs. The rounded pins and the flat pins are extruding to X, Y and Z directions and the grooves are on the side and the surface of the pieces. There is also a sort of step on a couple of pieces but most of these features are hidden inside once the puzzle is assembled.

The puzzle has a unique level 28-10-5-3 and we can say that it is easier than #3 because of fewer steps and possible assemblies of the pieces. But it doesn't mean the puzzle is easy at all. We can guarantee you that it is a hard puzzle and just disassembling the burr is quite a tough challenge. Reassembling the burr without any clue is almost beyond a human's ability.

It was the first time for Juno to use Hickory for our puzzle products. He loved its durability and the character that the surface can be very smooth. He wanted to make sure which of the following two options, using our original plywood or adding reinforcement splines on the end of the pieces, are optimal for puzzle production since he took the latter option long ago when we produced #1, and didn't remember how much work and effort were needed at the time. So, he decided to use Rose Alder for the reinforcement and as a result, the production process took a lot longer than using our original plywood, the use of material was economical though. We may not take the option to use reinforcement spline again.

Juno has a diabolical idea for #5 but we are unsure if we are going to produce #5 at this moment. People who enjoyed #1 to #4 expect something new or more to #5 and he has to make it happen.

The puzzle is sold assembled. The solution to this puzzle will be supplied upon request by Burr Tools file format.
