This is where we hit our first snag; the protruding bolts along the top rail of the trailer frame don’t allow the plywood to sit flush on frame. We considered drilling reliefs in the plywood at each bolt location but realized this wouldn’t remedy the problem for the trailer sides, which are designed to sandwich between the trailer frame and plywood and would also require reliefs/holes at the same locations. None of that sounded appealing so I grabbed the grinder and removed enough paint to weld the seams so the bolts could be removed. I ran out of wire and rain was approaching so this corner was left undone. All of the other bolts were removed and retained for future projects.
