This is a 9-piece burr with 4 sticks on one axis, 3 on another, and 2 on the last. I believe I bought this from Puzzlein in '04, their #145. The sticks are 3" long. I have no idea what level the puzzle is.

A metal hidden maze. The top and bottom of the disk rotate. There's a hole on the top and bottom for entry and exit for the ball (which is currently inside). I seem to have no instructions for this.

This is the same as the Hanayama puzzle of the same name, but came out well before the Hanayama version did. It's fairly rare, as far as I know. I bought it directly from Eldon Vaughn before he sold the rights to Hanayama.

Plus I could already see them in the solved state! I dumped them out and mixed them up and then sat there, stumped. Eventually I figured it out but it took a lot longer than I expected. A very fun, tricky puzzle that can also form a bunch of other symmetrical shapes.Construction of this puzzle is outstanding. ...

Brian Menold's description: I haven’t made any of Tom’s designs for a while and while looking for ideas I was intrigued by the simplicity of this design! A simple box with 4 seemingly easy obstructions uniformly spaced around the interior and 4 rather straight forward pieces. I also had acquired a nice piece of spalted beech that I wanted to be able to use on a box to show off the grain and spalting. A few of the spalted beech pieces required a small amount of filling in some softer areas...

The frame and pieces were very time consuming, with shouldered joinery, through milling on the connector pieces, and every edge beveled on the...

Coordinate motion puzzle. Remove the four pieces.In the third photo you can see internal marks on the (transparent) pieces from where they have been glued together with acrylic solvent. This is visible on other copies, to a greater or lesser degree, as all 140 were glued by hand and the marks varied. I have photographed the area with the most visible glue stain.
