I Forge Iron

What are these holes for? Not the top ones....


Recommended Posts

Back in the days of forging the anvils, those holes were known as "port" or "porter" holes.  The porter bars were used to manipulate the anvil during forging, tempering, and grinding, the porter bars had the square ends that fit snugly into the holes.  ThomasPowers is incorrect, some cast anvils most definitely had port holes!

If 'porter' holes were used to hold & manipulate the anvil while being forged, what purpose would 'porter' holes in cast anvils?

Handling/porter holes in a cast anvil or anvil body would be used to lift the still hot anvil out of the mold and move it to the next manufacturing station, finishing, grinding, or furnace to heat before weldinga high C face plate on.

Yes, I believe it is. Wrought iron and steel have similar resonant frequencies but cast iron and HC steel are quite different. The two being in contact means the compression waves from the HC plate self damp against the cast iron. Both Fisher and Vulcans used kind of low grade cast iron were it malleable they'd probably ring.

The self damping of two different resonant frequencies in contact is why my Soderfors is reasonably quiet on the steel tripod but will make your ears ring through muffs and plugs on a wooden block. Or why hanging a triangle directly from a nail results in a buzzing clank rather than a clear ringing.
