I've been tinkering with the pope and young broad heads that are in the YouTube videorecently posted.
When I was younger I owned a black smithing business. I made armor.
So I'm making these riveted and assembled broad heads thinking it would be easy to forge them, if one had the forge, anvile hammers, tongs, etc........ Oh right. I don't so back to riveting.
Then I bump into designs for a tiny forge made from coffee and soup cans. I have a decent bed on my vice, or a small anvile could be cheap.
Hmmmmmmmm.....
