Over the week end I made a Beam Compass or as we use to call them Trammels but I thing Beam Compass is a better description as the man said it does was it says on the tin.
Your probably wondering why I needed one of these old fashion drawing/marking out instruments in the modern days of cad. The reason is quite simple I need to draw large arcs in order to model the valve gear on the loco I'm building and my little lap top was just too small to be able to see what was happening so it was a mater of good old pen a paper to the rescue.

Very nice work.
How did you make the hex holes?

Thanks for the interest Will
They are not hex they are just 9mm holes for the 8mm (5/16") hex to pass through the locking rings pull down on the flat and keeps everything square and aligned.
Cheers
Stew
