I have been wondring how hard it would be to cast a dial out of concrete. The technique would require that one make a mold somehow using with raised splines for the hour lines and maybe numbers taken from a plastic sign set or something. I can see how to do this in theory, but have never experimented with concrete casting and I suspect there are optimal ways to dose the sand, cement and water mix.. and there are probably other concrete casting issues.
Has anybody tried this? It should be possible to get something that looks somewhat like stone without the difficulty of stonecarving.
