Thanks Ken

While all of this discussion of the gromet and screws is great, it should not be overlooked that the cutout for the servo must be large enough that the servo does not make contact with the wood on the perimeter.

Also, when placing a servo in a control surface application, the long axis of the servo need to line up with the direction of force. This allows the gromets to be held with the minimum of force, while doing the best job of preventing the rocking around of the servo when pushing or pulling.

I use the same method but I do compress the rubber ever so slightly.

1st time I've heard that one...good point!

What are the Pros & Cons for mounting the servo's output shaft closer / farther away from the control surface?

Btw, excellent thread for sharing basic and valuable information!

Me too. First off, it helps me know that the screw is actually making contact with the rubber, and second, the elasticity of the rubber will help prevent the screw from backing out - similar to using nylon washers.

Hope your basement doesn't get wet in the rainy season - oh, that's right - don't have basements in Hou.

Try this. Those are 3X48 socket head machine screws tapped into 3/8X3/4 inch maple motor mounts. The washers just touch the top of the grommets. Dan.
