For the thin stuff, throw in some fiberglass mesh/plastic screen and use gypcrete.
Then again, there is that expanding foam they've been using on monster garage - forget the name.

3d modelling is an option a true mental excercise in frusrtation

Try Alumilite, they make casting resins that are supposed to really tough.

Yeah, I thought about crete, but I'm going to start off with butterfly mines, which have thin wings, almost shaped like a flattened bird. I haven't tried either, but I think both plaster and crete would be too thin to hold up. Thanks for the ideas though!

Concrete sounds good. It's cheap, and , provided you already have the molds made for your mines, it should be easy to cast and use.

I thought you threw grenades .... not mines.

Sorry .... couldn't resist.

If it needs to stand up to some abuse, would reinforcing the plaster work?
If not ... what about concrete, you can sometimes get some leftovers off the back of the truck for the cost of a six-pack.

Happy Modelling and God Bless Robert

This isn't modeling related, but I thought I'd ask here. I'm trying to cast large numbers of dummy anti-personel mines for a military exercise.

I've got the molds almost done, but I'm having trouble finding a cheap enough material to cast the number of copies I need to make. Plaster is cheap enough, but won't stand up to the abuse of being thrown around. I'd go broke using the usual casting resin. Does anyone have any ideas? Thanks!
