Now and then I come across a puzzle which I find deeply satisfying in its balance of complexity and attractiveness. If it’s not too daunting an undertaking I’ll create a CAD design with the aim of 3D printing it. I get a lot of enjoyment from the reverse-engineering process and the insight it gives me into the designer’s mind. As I blogged about in my “Some Fun DIY Puzzles” post, I modeled Dic Sonneveld’s “4 […]

New Sliding Block Puzzle (Model #055)
I’m just back from IPP38 and this year I participated in the Puzzle Exchange. I’m still kind of reeling at the fact that I came home with two boxes stuffed with great puzzles. Seventy-eight of us swapped puzzles with each other and there are some truly beautiful and ingenious puzzles in there. My exchange puzzle was a sliding block puzzle which is a new genre for me. Here’s a picture of it: One thing that’s […]

MoreModel #360 is Ready
They said it couldn’t be done! They said it would cost millions of lives! They said I was crazy to try! Well, I showed them! Mwa-ha-ha-ha! Model #360 is finally done: And here’s a picture of the top showing the logo with the blue ink that takes me forever to add: It’s pretty hefty by the way, 11 1/2 ounces (325 grams). I have enough metal parts to make a hundred in total but will […]
MoreWebsite Housekeeping
Yesterday I made a bunch of changes to the Pyrigan website that temporarily made it inaccessible or made it render incorrectly. (I moved it to a new hosting service provider, Bluehost; I added SSL support so it now connects to “https://pyrigan.com” and shows a happy closed lock icon in the URL bar; and I updated and tweaked my WordPress theme to make it look a little snappier.) Now that I’m writing it down, that doesn’t sound […]
MoreModel #360 Update
Hooray! I received the first sample of Model #360 back from my machine shop this weekend and, in my humble opinion, it looks great. The nickel-plating turned out the way I was hoping. Here’s a shot of the top: My plan is to fill the engraved logo with turquoise-colored ink and hopefully that won’t be as ridiculously labor-intensive as the red ink was on Model #808. Here’s the bottom: Here’s the front: […]
MoreStewart Coffin’s #167 “Cruiser”
As I mentioned in my October post, I’ve been having fun making puzzles using designs I found on the web and one of them is Stewart Coffin’s 2D packing puzzle, #167, a.k.a. “Cruiser”. I’ve shown it to friends and family and it’s been a big hit so I reached out to Stewart about selling them. We exchanged some emails and met so I could show him the finished product: He agreed! I have his permission […]
MoreModel #360
I’ve been plugging away at my next puzzle, Model #360, for some time now. I made the first prototype out of wood, oak I think, back in the late 1990’s and it was pretty bulky. It sat in a box until I found a machinist to make me some slimmer models from delrin. Then I changed jobs and other interests and responsibilities consumed my time so it sat on a metaphorical shelf for another couple […]
MoreSome Fun DIY Puzzles
I was wandering around the web recently, looking at various websites devoted to puzzle collections, puzzle designs, puzzle math, etc., and found several that were simple enough for me to fabricate myself. The first one I’ll talk about is the “Blossom” puzzle by Bernhard Wiezorke and here’s a link to a description of it on John Rausch’s amazing website: http://www.puzzleworld.org/puzzleworld/puz/blossom.htm. As John put it, “Unbelievably, the four ‘L’ shaped pieces hold together after the last piece […]
MoreUpdate on Model #808
I have a couple of things to report about my Model #808 puzzle. First of all, I’m sold out (!). I’m kind of in shock because I had expected to sell two or three of them a month for the next couple of years, not all 106 of them in eleven weeks. Second, if you’re trying to find one, I would suggest checking with these fantastic puzzle stores who have the #808 for sale: Eureka! […]
