3D wooden puzzles

Hello to everyone here!  I am known as "The Puzzle Guy" on Youtube and the surrounding area.  I build 3D puzzles in the form of cars; trucks; tractors; planes; trailers; basically anything with a motor in it!  I have used Watco Danish Oil on my work since 1980.  My woods are walnut; birch; maple; butternut; and many imported exotic hardwoods. Each puzzle is signed; dated and numbered. I keep track of all my owners. I am grateful to be in a group with so many artistic and talented people!
