lead hardness tester boolits|lbt hardness tester reviews : maker I have used three different tools: the pencil test, Lee's hardness tester and the Cabine Tree Lead tester. They all technically work, the pencil test is the cheapest, the lee tool .
Sterilab centrifuge tubes that are autoclave compatible should be autoclaved for 20 minutes at 121 °C. For more help on how to use an autoclave, read this helpful guide created by the University of Washington.

Start a timer or note the start time so that you can be sure to retrieve the items shortly after autoclaving finishes. NOTE: DO NOT leave anything in the autoclave OVERNIGHT!!!
I have the luxury of a borrowed early Saeco Lead Hardness Tester. (U.S. Patent No. 3,524,343) It is machined steel and not the current version, made of some sort of gold .
I use a HR-150A hardness tester with a 1/2" diameter penetrator with 105 KG pressure, then measure the diameter of depression with calipers under a microscope, then calculate the hardness. Works pretty good. I have the luxury of a borrowed early Saeco Lead Hardness Tester. (U.S. Patent No. 3,524,343) It is machined steel and not the current version, made of some sort of gold .

My casting alloy (90/10% wheel weights/linotype), using a simplistic Saeco Lead Hardness tester, produces a Saeco hardness of 6 which equates to a BHN of 10. I have a . As cast bullet shooters we need a softness not a hardness tester as hard bullets have no place when looking for good, consistent, accurate loads. Soft bullets good. Hard . Looking for a accurate lead hardness tester. Most I've seen talk about testing on a cast boolit. What I need is something that I can use to test my lead while still 1 lb ingots.
The main way you target hardness is with the types of lead alloys you mix together. A Brinell hardness of 15 for pistol rounds under 1000 fps and a hardness of 18 for over and rifle .
I use my HR-150C Rockwell hardness tester for testing lead. I made a indenter with a 1/2" ball, then measure the diameter of the impression and calculate from there. That . This describes a method for the determination of lead alloy hardness. It is a simple, quick, and economical means to test hardness of unknown alloys, and I have found it to be .
