Casting an aluminum bronze farrier’s hammer

A bit of a long one, I know. This is the second hammer head I've cast with aluminum bronze. It was a tough one, took three attempts. The hammer was made at the request of our farrier. Lot's learned, or relearned, in this one.
Here's Gary's video explaining what a farrier is and does • Horse Shoeing Ana
