I haven't given up yet. There is a ...Hi Allard,<br />I haven't given up yet. There is a slightly different solution where I can get almost 4mm of clearance instead of 3mm. Is that possibly the one you are thinking of? I rejected it because it didn't seem to reduce the clearance of all the peaks. But in some magic way if I use one particular permutation of the solutions in the video and rotate one of the pieces it actually reduces the clearance by a mm for all the peaks. I don't understand why. I am off to do productive work (or at least try to) but I'm going to take a look at what is going on this evening.Dave Kirkebyhttps://www.blogger.com/profile/02387133988894709413noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-14272003418678915432015-05-04T18:19:49.038+01:002015-05-04T18:19:49.038+01:00Hi Dave - yip that solution will need exactly the ...Hi Dave - yip that solution will need exactly the same external dimensions as your first solution - I think you can do slightly better than that... :-) Tell me when you've had enough...allardhttps://www.blogger.com/profile/02137859069894390167noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-79786358704624374932015-05-01T18:59:41.031+01:002015-05-01T18:59:41.031+01:00Thanks for the response.

Coffin's book is on-line with some clues as to the woodworking skills necessary. He recommends a planer that I don't have but I think I might be able to make the pieces well enough with my table saw and a little sanding.<br /><br />As to your additional solution. That was very cool. I had a very strong feeling that I had found all the solutions and I enjoyed seeing how wrong I was.<br />I made a short video of demonstrating what I think is the solution that you were describing:https://youtu.be/0pd8xbhT-Dg<br /><br />The alternate solution seems to not fit any better than the solution in the first video in the version of the puzzle I have. It will be really interesting if there is yet another solution. <br />Dave Kirkebyhttps://www.blogger.com/profile/02387133988894709413noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-71756442012665924572015-05-01T07:56:01.281+01:002015-05-01T07:56:01.281+01:00Sorry, can't tell for certain whether Stewart ...Sorry, can't tell for certain whether Stewart made that copy, but can tell tell you that lots of people make the puzzle - Stewart encourages people to make his puzzles and sell them! :-) Some very talented woodworkers make copies of his puzzles that are serious works of art (Peterson, Devost, Buie, Krasnow). <br />Solution - if the tolerance is 3mm below the lid with your animated solution, then I suspect that your box is not quite as snug as it could be on this puzzle and allows a few false solutions... although it still clearly makes for a fun puzzle! :-) allardhttps://www.blogger.com/profile/02137859069894390167noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-29573180010815176642015-04-27T21:36:17.562+01:002015-04-27T21:36:17.562+01:00Thank you very much for your reply.

The puzzle is beautifully constructed and that surprises me that somebody would do such nice work on a copy, but it is certainly possible. I wonder if Stewart Coffin knows of the people that made it.<br /><br />Solution not quite right:<br />This idea was a complete surprise. I went back and matched the physical puzzle step by step with the animated solution and I can't see a difference. The lid slides on and off very easily with this solution. The blocks in my puzzle are 20 mms thick and the clearance below the lid is about 3 mms.<br /><br />Is it possible that my puzzle is not quite identical and there is another solution for the Coffin version?<br /><br />I notice also that my puzzle seems to have metric based dimensions. Perhaps that is another clue that it is not a genuine Coffin puzzle?Dave Kirkebyhttps://www.blogger.com/profile/02387133988894709413noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-7880338219798911692015-04-27T17:50:56.954+01:002015-04-27T17:50:56.954+01:00Hi Dave - thanks for posting...most of Stewart'...Hi Dave - thanks for posting...most of Stewart's works have pencil inscriptions with the puzzle number and his initials on them somewhere... BTW I suspect that your solution in the animation doesn't quite work - is the lid a little stiff when you slide it on? It shouldn't be... and if you adjust things a little you can get it to slide on freely... :-) allardhttps://www.blogger.com/profile/02137859069894390167noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-58109841745389175922015-04-27T08:19:42.038+01:002015-04-27T08:19:42.038+01:00My daughter loaned me the puzzle.

I enjoyed the puzzle enough that I thought it would be fun to make a video out of it. https://youtu.be/Fh6hf0Difkg<br /><br />It would be great to hear about any errors I made in the video or some information that I should have included. In particular, I wondered whether Stewart Coffin or somebody associated with him had made the version of the puzzle I have. It is very nicely constructed, but it is somewhat different than the version of the puzzle shown above.<br /><br />Dave Kirkebyhttps://www.blogger.com/profile/02387133988894709413noreply@blogger.comtag:blogger.com,1999:blog-1325321154517773060.post-25324804644227026802011-05-16T07:38:29.613+01:002011-05-16T07:38:29.613+01:00...a fish supper was the least I could do after yo......a fish supper was the least I could do after you put me out of my misery, Louis!

I kept thinking that the hole in the lid must be craftily shaped so that you can get the lid on with a piece barely sticking out.
