How to cut a skull properly

Can anyone chuck up some pics of a skull cut correctly?

Im looking at chucking a head i have on the wall but just worried about the angle i cut the skull.

If i put it on a block of wood with the full skull intact the antlers stick a hell of a long way out from the wall, would prefer they go up parallel to wall or thereabouts... Otherwise no chance this is fitting in the house.

Cheers

Put it on the outside of the house

put it on a flat surface and block it up to the angle you want the antlers to sit, then get a block of wood or a book or something the right thickness of where you want to cut the skull,rest your pencil on the block and slide the block around the skull, drawing a line parallel off the block where you want to cut it. hope that helps.
