I am looking for a link or store that has rivest like the older 80s gi joes had or a source of suitable pins that could be used to interlock articulation.
I am trying to simplify my from scratch figure building though all the rivets I can find in any stores are too big for action figure use.
Any help with this would be great as I would desperately like to finaly get arround to making prototype figures that I can mold cast up without relying on any existing action figure parts.

On the pins and/or rivets, looking for something the is inexpensive that can be bought in bulk.
