Yes, iron of an unknown alloy with embedded gravel. Sort of like a stony iron meteorite only far less valuable. Not totally worthless either, which is why I want to cut it. Google "Plateau Putorano", Shirokovsky and Mendota if your curious what I might have.
Approximately 11" X 16" X 23" but with all roughness would need a horizontal saw with a 12" X 17" capacity. Looking for blade / cutting fluid recommendations before I take it to a big shop and end up with a huge bill and an uncut bolder. Real meteorites are typically cut on a diamond wire saw. Prices I have found run over $100 per slice. Ouch! Well worth it if mine were real which sadly it is not. Yes, I have had it tested...
If I can get one thick slice out of the center I have a small local shop that can cut hand sized specimens for me. Practice a bit and know for sure which blade(s) will work before bothering a large machine shop to cut full slices. Suggestions on how butcher the one thick slice would be appreciated too. I'm thinking cutting from both sides with a large abrasive blade might work since I managed to get a small chunk off this way.
