Bit out of the ordinary but I've been asked by a school to fix a stainless steel sword into a large limestone rock they have in their school garden.
I considered coring out a part, putting some bolts through the blade then setting it in concrete but just wondered if a narrower hole filled with Epoxy may be better. Obviously the kids are all going to be trying their best to pull this out so it needs to be well fixed.
Any advice would be much appreciated!
