I found some interesting information online today about hardness testing. I am posting this here for my own purposes, so please don't question me on the authenticity or veracity of these claims. I have not verified the content.
Testing an anvil top for hardness - two popular methods:
Testing an anvil top for hardness - two popular methods:
1 - Drop a 1" steel ball from 10" and record rebound on several areas of the top - Measured from the bottom of the ball to the bottom of the ball at the peak of the first bounce at center of anvil over waist
--- Anything below 40% is generally junk and some ASO's test as low as 10%
--- 50% (5") is OK but a relatively soft anvil
--- 70% (7") is an average good anvil
--- 80% (8") and up are top quality anvils.
2 - Hit the top plate moderately hard with the ball end of a heavy ballpeen hammer. Dimpling indicates a top too soft to stand up to significant usage.
