There are heaps of large compasses with an ordinary pencil fitted, but they are not very good on burls or rough wood.
So I came up with these prototypes which will take a Carpenters pencil which are great for marking those large diameters.
The tubing is just drilled & fitted with a self tapping screw, but I suppose they could 404279404278404277have a nut tacked in place & fitted with a bolt.
They are about 300mm long & made to fit the only tubing I had.
