Took a few more pics of my axel design. Frame is made out of 1/8" 2x2 tubing. Sides are all removable in case I need a flatbed or I can leave the sides on and remove the ends and put 8' logs on it with a foot sticking out each end. Inside dimensions are 36"x6'.Outside of tires are 5',the same width as both my tractor and pioneer.
