Yes, I have built things. I have built a wooden boat and many other things.  I did not have the idea my grandpa came up with the idea.  I worked with my grandpa on theses projects in his tool shop in there home. I used wood, a sander, and more things that I do not remember. When I built it after we went to the Scarsdale library and played with it in the pond. I was about 6 or 7 when I made it.
