By sand, do you mean that I have the gear for it? Hey I live in Western Australia, it's just one big sand dune! I haven't got a milling machine, let alone a CNC mill. I've got access to a milling machine but for this sort of casting I'd just use the shaper and the lathe. Shaper gives an awesome flat surface. Yeah. I love making stuff. Or stuff that makes stuff.
Or 'Sand???' as in its not billet? Yes. It's a rough sand cast. Has porosity too. Was almost tempted to fill a couple of holes to be on the safe side. They're okay though. You can also tell by the surfaces where it has been machined. No drama with sand casting, as long as you keep the temperatures consistent and account for shrinkage. Hey, look at Maico's!
