Re my question

My CNC router easily has enough Z-travel to cut a mould that 'deep', however it would still have to be split into 4 parts since the machine isn't wide enough. That shouldn't be too big a problem though as they could be simply glued together.

The difficult bit here is probably fabricating a drawing of the part. Have you got any drawings which could be transferred into a CAD program to make a 3D model?

Thanks Johnathon I only sketched out what I wanted to do .It changed as I built it up .Probably frowned on by your community Ideally it would a better design if it was taller & less depth .
Thanks Peter
