You could make a flexible silicon mold perhaps?
Pour the wax in, bend the rubber stuff, take it out, pour another lot of wax, etc etc.


That's actually a rather good idea. I have been thinking about how to make some moulds for different objects that are rather awkwardly shaped, and that approach would quite likely solve most of the problems. Some of the more complex Peruvian star maces are positively screaming to be cast in bronze, using that method.

A mould for a schytian arrowhead, like the one below, might require some creative thinking ...

Nasty little sucker, ain't it?

Just make a regular 2 piece mold, and have a cone shaped plug that fits into the base of the mold so the socket won't fill with bronze. The plug would have to have 2 tines at it's base to keep i from falling into the mold.

Massi - WTF? It's called a sling. You use it to throw rocks farther and faster than you could otherwise. That's all.

Would be a bit hard to make, as the arrowhead is triangular (has three vanes). The barbs could be made with a file, making the mould simpler.

Or, are you thinking something like this?

A triangular arrowhead like this, makes some real nasty wounds, that take a looooooooooooooooooong time healing. The Scythians compounded that by smearing them with poison and a bacteria soup (Clostridium tetani, C. perfringens, etc.) made from rotting flesh and other unhealthy stuff. Very likable fellows  Shocked

My first thought about greencheapsk8's idea was that it would be useful for casting a bunch of wax arrowheads and connect them in a tree fashion and make a lost wax arrowhead mold.Of course it could be a glandes tree as well.

My suggestion. Two part mold:
...

So they go together, pour the wax in, take it out, etc.
Or use the arrowhead and directly sand cast it, no wax to mess with! Cool

Hey, i hope this is okay with the admins, but this site here has those 3 vaned suckers.
http://www.bronze-age-swords.com/aegean_swords.htm
These are simpler, having the whole blade done in one tapered pull, and the cone piece as a core.
Towards the bottom.
You could buy them, but wheres the fun in that? Roll Eyes
