My little shop attempt at a lead hardness tester. A little milling, turning, and powder coating. Now to make some various test bullets from known lead to make a reference chart.
Homemade Lead Hardness Tester (click on images for full sized view) I bought a Lee Hardness Tester, and it was just too hard for my old eyes and shaky hands to use. So, I used what I had around and made one myself. I have a 1/2 ton arbor press which is perfect as a starting point. There is a fairly easy way to measure lead hardness if you can get some pure lead to start with. Take your sample of pure lead, a small ball bearing and the unknown lead sample. Place the ball bearing between the 2 samples and squeeze this sandwich in a vise. The formula I mentioned above is in an article written about using the Lee Hardness tester. You can plug that formula into Excel and create a spreadsheet for any homemade tester. The author found the formula in Wikipedia. Here's a link to his article.
Use a .156" steel ball bearing (I mounted mine on the tip of a steel cone) and apply 60 pounds pressure for about one minute. I use a hydraulic pressure gauge, but you can use a common bathroom scale on a drill press. Measure the diameter of the indentation, then use the chart to determine the hardness.
