Thank you for the response
I had read a post about anvils not being parallel that gave me the impression it was intentional, your answers make prefect sense
True, screws are relatively "new" in the big scheme of things, I didn't think about that.
My wife and I have talked about our interest in blacksmithing for years, now that the kids are on there own, we are pursuing a new hobby
From what I have read I'm going to take some heat for this, but my first project is going to be casting a steel anvil.
I am planning on documenting the whole process in a thread start to finish, design through machining
Thanks again
Tim
