The complication comes from two parts, one is that everything is under water (except the motor). Secondly, because I'm trying to look at the flow structures around this plate, it's pretty important that whatever holds the plate is influencing the flow as little as possible. That's the reason for...
DO you think that will allow for enough motion (75 degrees?).
The pivot shaft was just an initial idea so if there is a better solution I'm happy to change it.
The green (the L) is fixed. The blue plate is what I want to be able to adjust the angle of.
And yes it needs to be remotely operated so I can automate it.
I doubt I'll be able to use cables as the forces will be fluctuating and I need a rigid connection.
The arrows were just to describe the rotation of the shaft in the housing. The red arrows were representing the translation of the 'internally-threaded' piece.
And yes I had thought of a worm-drive, but thought that I would need more gearing to achieve this.
My main concern is to make the...
Speed is not an issue at all. I just want to move it into place and it'll stay there for a while.
As for moments, the plate will be ~200mm wide by ~100mm high and immersed in flowing water. The moment will, of course, vary with the angle, but I don't imagine it will be too high.
I'm not sure if the picture worked so here it is as an attachment.

Howdy all,
I'm working on a little project that I need some help with. My objective is to hold a flat plate, but, using a stepper motor and encoder, be able to change the angle that this plate is at.
My rig will consist of a motor (at the top, shaft pointing down). There will be a casing from...
