There is no answer but omg...why would someone put the pieces in the base. Keep them together in a bag...set them a the base of the headstone...DON'T put them in the base! I don't understand that at all.
That's SO much hard work. That's beyond commendable what you're doing there.
If you can't fix it, you bury it in front of or behind the headstone, that way in 100 years someone with better tools can fix it. Theoretically. They followed those directions, but then followed up with concrete. Giant mess. I am missing many skin layers on both hands. It hurts.
I am getting there. This was the first stone I dug up Monday AM. It was leaning and I thought it would be easy, but the base was broken off. It got cleaned up and epoxied yesterday, then replanted and leveled today. 1794.
And James got another 8 hours or so of detail chisel work then we epoxied today. He will get infilled hopefully tomorrow.
