I went to a flea market this morning and picked up the hub off an old wooden wagon wheel for $2. Its the inner wrought or cast iron hub that was used on the wagon wheels that had a wooden outer hub, wood spokes and rim with an rim of iron fitted on.
Found in numerous front yards and cheap steak houses as lawn art/decor.
It's basically a long cone shape exactly the right size for forming vambraces, plus it slides right on my 2" t-stake like it was made for it.
