I'm currently in the "this has been fun and learning a lot!" (seems a lot of my projects work out that way....)

If you can think of anything you'd want cast, then maybe there'd be a use for it.  There are some rules for casting.  If we go the 'lost foam' route - you construct the object out of styrofoam or insulation foam, we pack it in a bucket of sand and pour the molten metal on it.

2 part casting with flasks (as m morton mentioned) - there are some rules as to what the shape the object is due to the fact that you're taking a pattern / object, cutting it in half, and packing sand around each half... then have to remove the halves.  Think in 3D concerning the sand and you can see how the rules come about.

Any kind of precision object (something you add to reloading press or a firearm) would need machine work afterwards.  shooter has tooling for that, but I do not.  I can grind, polish, drill holes, and tap some common sizes.  That's about it :(

m morton:

It's a short drive!  Most of them took that trip years ago and never came back.
