    Puzzle: Squaring a Triangle

    Super neat puzzle. Thanks!I wanted to make several for friends so took the time to build a jig. I scaled to 5 - 5/8" and am using 1/4" birch plywood. By mixing pieces from different iterations, grain doesn't give away the assembly.

    Captive Ring Puzzle

    You provided the solution to "what can I make for the grandchildren this year?" THANKS! Neat puzzle. So I made a dozen. I did use a shortcut that may be of interest to those making multiple copies. I used a hole saw in my drill press. Once the saw had cut about an 1/8" and the pilot hole had not gone all the way through, I removed the pilot drill (i.e. the 1/4" twist drill). clamped the workpiece in place and completed the cut with the hole saw. Then I sanded the edges by mounting the blank discs in the lathe and sanding as the disk rotated fairly slowly.You might also be interested in the note I attached to each gift puzzle:Thisyear I decided to make a simple little curio for a few friends —somethingtotally useless, just a novelty with a brass ring secu...

Qualityhardwood lumber is becoming very expensive and there is a growing market inreclaimed woods. I went on lineand ordered several pieces of oak and maple. Responsible dealers always share the origin of the materialsthey sell. Imagine my surprisewhen the beautiful pieces I ordered came with a tag stating that the wood hadcome from “shipping coffins” which had been stored in a New York City warehousefor many years. Inmore detail than I wanted to know, I learned that the wood used in these curioshad been a coffin in which Eric Weisz’s body had been shipped from Detroit, wherehe died to New York City on October 27, 1926. (He is now interredin the Machpeiah, a Jewish Cemetery in Queens.)Iwondered why, in making your gift I had such a hard time keeping the ring inplace.Couldit be because the wood in your gift had once transported the body of EricWeisz, born in Budapest, Hungary on March 24, 1874. The same Eric Weisz the world came to know as Harry Houdini?
