Thanks for all the feedback! One reason that we’d consider doing this is we have a LOT of scrap wood/stuff laying around from various building projects, and if you’re starting at 0 jump cups and need a lot, this is an affordable way to start while you build up your metal stash. Or plastic, depending on your personal safety views.
I like the ideas too, of putting a block on the back of the standard to hang the ropes off of, and also the idea of a wooden “dowel pin.”
Wonder how well the blocks hold the jump rail?
