I don't consider myself to be in the category as most of the great builders on this forum. I simply like old iron; Trucks, tractors, equipment, trains, and sometimes cars. I build what interests me as a hobby. AS far as building, I kind of learn as I go. I build for enjoyment. When building becomes nerve racking I stop. I truthfully don't like to tie up as much time in a build as I have in my current build. My models are never perfect, but they look good enough for my shelf.
