Mark, you could just attach the wheel base
panels ( The triangle and
the shaft ) directly to the wood... Only 8 bolts there, plus the middle
iron support brace. I am not getting why you need to sandwich the base
panels between the wheels and the wood?
Thanks for the question
Pedro. I hear what you are saying, and it may have been quicker to do
it that way, but keep in mind you will need to have a bolt head
protrude through and I wanted a smooth shoveling surface for days when
we use it for mulch or sawdust. The metal also functions as a splash
guard where water is most likely to splash up to when going across the
creek.
