A mirror floating in water will not be strictly horizontal. This will depend on the exact shape of the floating pads, and I suppose it is impossible to make pads to the required accuracy. That's why there are mainly two types: with mirror standing rigidly on legs and adjusted with bubble levels, or using a liquid surface. But not floating mirrors.

The assumption is that the fs mirror is a consistant thickness and the foam pads each would be cut the same size. What do you think? Sam [PLAIN TEXT VERSION OF MESSAGE AUTO-GENERATED.
