Having seen other posts about making a Turner's Cube on here, I've got a few spare days and am gonna make one from acrylic (should be nice n polished, I'm diamond machining it).
My question is: which depth should the first circle be please. eg: if the cube is 50mm on each side, is there a formula to tell me what depth I should cut the first circle at? I reckon it would be a function/ fraction of the overall width of the starting cube, say about 75%????. I want to cut each of the faces' circles (picture a dice numbered face 1-6) at the same depth so that it's automated.
Any ideas gratefully received. Many thanks in advance.
