tagua nuts turn easily, if you have some small screw drivers, or some files
with no handle(the kind with the pointy metal bit still showing.) even large
nails in a pair of pliers. with a grinder to make any shape you want, I
turned one(sort of) attached onto a hand drill, and used a screwdriver on
it(it blew up because it didnt stay on the drill, but with a lathe thats not
a problem)

Nothing small to use on the tagua nut and
I am still not sure what to do with the pod.
