Here is one of the molds for casting a basic soldier.
And this is a mold for sword, musket and a bird. I hit on the idea of putting a cork in with the mini when I make the mold so it starts out with a good pouring hole. I had to cut a vent for the sword to cast well. The musket and bird cast well as is.
The results of an evening's casting. Poorly cast bits were remelted, but overall I have been getting pretty good casts within the first couple of tries.
You might notice the Highland cows - I made a mold for that mini and started casting it within an hour - and in spite of one of the cow's ears sticking into the mold, not along the parting line, it cast well right off the bat.
