Drill Press Lead BHN Hardness Tester

Just using my Harbor Freight Drill Press and a 10 dollar bathroom scale. If you don’t have a drill press you could use a big “C” clamp as well. To get the Brinell Hardness Number of a lead ingot.
Full disclosure : You should really use a ball at the end of the drill bit or at least round it off. I just did not have a trash but to grind up.

Here is the link to the Brinell Hardness Number Calculator I used.
