@downsyde By Jove I think you have it.

Protest as much as you like and complain about my garbage - you never realised until I made the caluclations - only now realise the veins are actually graphite filled and expanded cracks.

pretty fundamental I would think, hole/crack in your thinking.

You'll never admit, it but I did you a favour.

In a way its my fault you say garbage because I assume too much about what to me is obvious. Though I did clearly sat 2m x 2m and o.5m. Impossible to imagine anyone would think a round hole would exist orthat 0.5m meant diameter..
