Here is a collection of 3D mechanical puzzles I have made. These are great puzzles for displaying and also fun to play with. Great to have sitting around at a party
or social gathering. Most of these are pretty tricky but solvable. All are constructed from hardwoods. These designs are public domain and most are courtesy of
Stewart Coffin. A pioneer in the field of puzzle making.

Entanglement puzzle.
This is one bad puzzle. The
goal is to remove the moon and
rope assembly completely from
the frame. This is one puzzle I
do provide the solution for
when you buy it. All 5 pages of
it!
$30
Broken Heart
This is another entanglement
puzzle. Can you put the broken
heart back together by getting
both halves on the same loop?
Tricky! Requires some lateral
thinking.

Half Hour Puzzle
A six piece cube puzzle that only
assembles one way. The name came
from the designers philosophy that it
would take the normal person about a
half an hour to discover the solution.

Convolution.
A seven piece cube puzzle and one of
Coffins' classic designs. This puzzle
has one solution and is difficult to find.
There is one particular "turning" move
that must be discovered before the
solution can be acquired.
