Rotation lockout mechanism ideas
(OP)
I was looking for a rotation lockout mechanism. Hold perhaps a 10-20 ft-lb moment. I was looking for something on mcmaster carr but could not find any thing. I am not even sure what you would call it. Something that would be used at a pivot point between two pieces of approximately 1" x 2" aluminum extrusion, and could be adjustable angle. Thanks

Depending on what you are trying to accomplish you might look at throttle arrangements for large boats. These systems lo also lock by detent and are operated by moving the handle to one side to increase or decrease speed. An older throttle has the operating arm rotating about a stationary shaft where the handle is rotated on it's axis to release tension provided by a screw operating against the stationary shaft.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

If overlapping, use a clamp knob or handle (knob or handle on a threaded stem, engaging a tapped hole on the far piece of extrusion).

Besides the hand operated lever here is a little different approach to lock rotation using worm gears. If you need something small and with high precision I would check with some one like Rhino Mechanical. If you can tolerate a larger and more robust system you could look at one of the many worm gear valve operators like the FNW.

I've used the FNW type to tighten and hold brake bans on large deck winches used on Shrimp Boats.
