Thanks for posting that. I like the creativity of the original post’s DIY solution, but I’m happy to see there is an engineered solution that is commercially available. That the solution is nearly identical to the DIY validates the OP’s design, but the commercial solution is both simpler and looks more reliable. Perhaps it relies on more machined components, but that should still be within the capabilities of a 3rd world machine shop.
