Review on Wood Trick Mechanical Assembly Constructor Puzzles and 3-D Puzzles by Mike Shah

This is my second Wood Trick Build, the first was on a hot rod. None of them worked "under authority". The biplane had parts that fell out during winding. The "hand wheel" that is supposed to unlock the drive doesn't even turn the shaft to loosen the gear that holds the gear. I am a very experienced builder and have built over 25 Lego sets (large), Rokr sets and UGears. Wood trick is by far the worst! I have to admit the laser cut was excellent, very little trimming and only a couple of snips. I bought this kit as a static display although I'm disappointed that it doesn't work. still a cool looking exhibit.
