Storm coming in, humid in my shop today

Stephen Shepherd in the State of Deseret

>Here is a cat gut hygrometer I made for our 19th century weather station. I am making a variety of philosophical and scientific equipment for our Base & Meridian House and Observatory. Fun stuff.

The gut (not cat but sheep intestine, cats are not long enough) will twist and untwist with changes in the humidity. It is more responsive than a modern dial hygrometer and just as accurate.

Real humid here today.

So how did you calibrate it?

>I had to move it from different conditions from very dry to very humid. I had mad a prototype with a much longer gut but it twisted way too much. Even the finished one had to be shortened to calibrate it correctly.

Here is a moon phase indicator I am building based on globes and planet models of the nineteenth century.

The moon is paper mache reinforced with cheescloth and the cover which will be painted black is coopered pine veneer bent and held in kerfs on each pole. Paper is glued on the back to reinforce.

One of the most unusual things I have ever made.

>You bet!

Let's get the stock number & order a few dozen days like that!

Today's looking good too: 71 degrees (21C) and 70% Humidity, so far.
