when I made sockets for chisels, I just used black pipe or tubing and a tapered cone mandrel to drive then down onto it hot, after swaging the small end some first, then cut the socket off the pipe for attachment to the chisel. I bought the chisels at flea mkts that had the handles missing and someone used a metal hammer on the sockets to drive them, destroying the socket part. cut off the old socket and arc welded or torch welded the new socket in place, then forged for a nice transition . If you look inside old chisel sockets you can see the forge weld inside, from being fullered wide, then wrapped and finally forge welded over a mandrel, the inside is usually a cold lap seam.
