depth gauges

[pekelney]

Folks,

Thanks to Cod, Drum, NHHC, MARAD, and others, Pampanito now has depth gauges.  Some real, some replica.  The replica's are all pressure gauges, but not calibrated for depth and without the fancier features that are on some of the gauges.  See:

The wider availability of CNC laser cutters has made creating replica faces much easier.

We updated the barometer notes as well:
