Pentonimo puzzles from twelve different types of wood – gifts for my Grandsons.
These were a real challenge for my skills at the time, I used a machinest file on every edge to get every piece exactly right. Making the boxes I decided to rout the inset after gluing up. I did this with the maple frame on the wrong side of the fence and plunged the bit in! I know, dangerous and risky, but I didn’t know any better. Now I would do things differently, live and learn.
The wood used is: Cherry, Red oak, Ash, Black walnut, Black locust, Poplar, Vertical grain fir, Pedauk, Hickory, Maple, Bubinga and Yellow heart. The base dimension is 7/8” +/_ 0.010” and 1/8” roundover on all edges.

Oh that’s wicked! I didn’t know about this version of the puzzle – and the version that I have just about drove me crazy.

I have a very similar puzzle except that it has one extra piece. It is a “2×2” unit square (bottom right), which, I know, is different to all the other pieces as it has a unit area of 4 instead of 5, but it means that the puzzle is then done in a square box that is 8×8 units.

Yours is very well made. You did a good job of it. Good idea to include the solution.

One extra thing that I learned though is that it is a good idea to line the box with felt or similar. Without that, the incessant click, click, click that the pieces made as I tried to solve the puzzle just about drove my wife crazy!

That would drive me nuts trying to figure out.

Looks like a good job on the build.

we are reading a book (car trips) to our daughter that features Pentominos in it. didn’t know they had to have 5 squares only, and all had names. This set is beautiful.

That is very nicely done. The contrasting woods gives an added visual interest. The box is a great idea too.

Hi Tootles, google – “pentonimo solutions”, bingo you get them all. I use the congruent solutions as a memory test in my spare time.

Thamks Exelectrician, that is quite a set of solutions that are out there.

I have my own set of solutions that I had to work out on my own. I first saw this puzzle over 15 years ago so the one that I made, and that I posted a photo of, was made sometime soon after that. The Internet has come a long way in those 15 years because I doubt I would have found all those pictures then.
