I'm attempting to make the rigid equivelent of a gate tensioner/turnbuckle. I'm doing this for a couple of reasons:
- I like the idea of not fussing with cables
- I'm using this experience to learn about the technology behind the turnbuckle
I've mocked up something that almost works. I've connected two hook-bolts to a threaded rod (5/16-18-36") via connectors.
It seemed like it would work in my head; I thought I would just be able to tighten one of the connectors to tension the gate. However, in practice, all I accomplish when tightening a connector is tightening one side, but then loosening the other side. The devise comes apart and fails miserably.
What kind of mechanism would it take to make this work as expected? In summary, I want to shorten the length of the device/rod by tightening a connector.
For bonus points: What is the principle called in Mechanical Engineering theory that would explain the problem where one side tightens, but the other side loosens?
