If you’re working on bunny hops, I’d recommend making this. I’ve gone through a few iterations, and this is the one I like the best. The top board springs back into position if you hit it, so there’s never anything to reset. The springs are trampoline springs you can get off amazon. One change I would make is to justify the diagonal braces to the outside of the uprights. I didn’t do this, so I had to make two lines of bolt holes. The bolt holes are 1” apart, so you can set the barrier at 1” increments.
