heres a pic of where i am so far, not much progress. this is somewhat of what the tracks will look like. i need to space the shoes out 1/4" and i am thinking of using 1" x 3 1/8" shoes as opposed to 1 1/2" x 3 1/8" to get the look but only if the spacing is enough for the drive wheel and wont create binding.
