Reloading Dies. Reloading Presses & Kits. Inline Bullet Feeder. Automatic Processing Press (App) & Accessories Instructions. Powder Handling.The hardness tester consists of three items (see fig. 1). They are: Indenter – At first glance looks like a regular seating or reloading die. The body of the indenter is threaded 7/8 X 14 in order for it to screw directly into all standard reloading presses.
I also use a Lee Hardness tester mounted in a microscope. It makes it's use fast, easy, repeatable and very precise. I also have “calibrated” my Lee scope using pure lead and using the formula for conversion. The Lee tool also measures in .001” so it is easy. The Lee table of BHNs is pretty close. In the post it talked about the chart that comes with the Lee tester for the given readings not being "totally spot on" and one of the forum members did a more extensive series of tests and came up with a more accurate chart. A table light is used off the side for illumination. The smooth and easy up/down adjustment of the scope makes the Lee tool easy, quick and consistent in use. Larry Gibson
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 reliable and accurate. Here are some things I recently tried in regards to my Lee Microscope stand. Last fall, I bought a Lee hardness tester for some testing of different alloys and how fast they age harden. well, two weeks ago, I finally started my alloy testing, which includes lots of hardness testing. after several tests, I realized my microscope stand was a poor .Upper and lower limit of hardness can be preset; When the tested value exceeds the limits, alarm will send out automatically to make convenient for the requirements of batch measurements.
The Lee Lead Hardness Testing Kit will determine the exact Brinnell Hardness Number of an alloy in a simple six step process. The process involves pressing a hardened steel indenter ball into the bullet through the use of a standard single stage press.
