Salute, All !!!
This may seem a little odd, but:
I am sketching out the design of a telescope mounting. I needed some graph paper, a compass, protractor, ruler and a sharp pencil with eraser. Then it hit me. I have all of those tools aboard my U-Boat !!!
So I started a new career, left the boat in port and scrolled out to the Bay of Biscay and made my sketches !!
The lengths are not precise, but they are good enough to work out a cut list of the wood pieces !!!
Good 'ol SH3, more than just a simulation !!!
