During his sleeping periods, which are frequent and fairly long (a family trait I'm told), I have been experimenting with an old pressure gauge - let me explain. I picked up a 1960's brass pressure gauge for next to nothing and, at the same time, bought a quartz clock movement and a set of hands. The gauge looked a bit like this one. The face is the one behind it...
I downloaded a nice clockface off the internet, printed it at the right scale, put the whole thing back together and bingo, we now have a really great looking brass wallclock for the boat (to match the barometer).
I might have a go at doing a few more. You never know, it might turn into a cottage industry. Orders are now being taken!
Now, I must listen for James, he might wake up in the next hour or two.
