Hrmph...I think I may need to rethink this whole thing again.

Exact measurments are 1 3/4" wide.

The hole is less than 3/4" deep too, (1 1/16th too shallow) so Even if I did widen the mounting, it wouldn't mount flush.

Is this a common size for regular needle guage hygrometers?
The ones I've seen online more often seem to give the full diameter and not the mounting diameter needed to set the guage into the wood.
