Quite a while ago there was a thread on here that had some good images of the historical process used to make the spiked/cone-shaped bosses. If you do a search, you might be able to find it. Even if the pictures aren't there anymore, I'm pretty sure the process was discussed. If I remember right, the bosses were forge-welded into a cone, and then welded to a flange. Spiked bosses were made pretty much the same way. That's all just working from memory.
