Thanks for all the replies.
gianluca100: I'm not too sure of the weight of them, I don't have a scale to weigh them on at the moment.
fishfinder401: My anvils are all back home, at the moment I have access to a 125 pound JP from England, and I also used a mandrel/bick that I had made for making sockets on, I'll attach a picture of them.
darwin: I used half inch key stock to make them, to form the socket I flatten out one end in a fish tail shape to the size I wanted then I use the cross peen end of my hammer and the side of the anvil horn where it meets the anvil to start the socket to bend into a U shape, then on the anvil face I start the roll of the socket, then insert it onto the end of the mandrel/bick and finish shaping it.
adb: Those 4 will fit on a 3/8 inch shaft with a recessed end so that its a smooth transition from point to shaft.
