Have you tried drilling/poking the bottom of the hole to see if it is a soft metal? Looks like someone poured something molten down there and it ran up the touchhole a ways. Woods metal? Babbitt? Maybe you can just melt it out.
It isn't lead, I tried stabbing it with a blade on the end of a stick, didn't leave a mark
Hi:
be a bummer if there was a load under the obstruction.

I'm kind of waiting at the moment. When the spike laughed at my puny efforts with pin punch and sledgehammer, I decided the only safe way to remove it was to burn it out.
I ordered an American book called, "Build an EDM Machine", once it arrives I'll know if it's possible :thumbsup:

Either of these two devices will remove your spike with minimal effort. The spark eroder weighs about 10 pounds & is portable. The EDM machine probably weighs as much as your cannon & will probably be found bolted to the floor of a shop someplace. A carbide endmill or Hi-roc drill are other options, but if the hole is as long, narrow as I expect it is, then you will probably break off the tools & have an even bigger problem to deal with.
