Alright guys, today I wanted to do a quick tip. We are going to be talking about calculators because smart people use calculators, right? So, I'm not going to be talking about this kind of calculator. I am going to be talking about a lead alloy calculator. I'm going to show you what a lead alloy calculator is and briefly explain how to use it and where to get it. This calculator I have was obtained from the cast bullet forums. It is made by bumpo628 and has been revised several times, with contributions made by other users. The purpose of this spreadsheet or calculator is to help you calculate the hardness of your alloy, as well as the percentages of tin, antimony, copper, silver, lead, and arsenic. Let's say, for example, that you have two or three different alloy sources. One of them is from stained glass window scrap, which you obtained from a friend who works at a stained glass window shop. The other alloy you get is a mix of foundry type and monotype that you order from a guy on Facebook. The foundry type monotype alloy is really hard, so hard that it could snap in half without bending. On the other hand, the stained glass window scrap alloy is relatively pure and soft. With this lead alloy calculator, you can determine the content of the alloys you have. In a casting manual, there are known alloys that you can cast with, such as biotype, pure lead, 10 to 1, 20 to 1, Lima number two, hard ball alloy, and many others. Each of these alloys has a known content of tin, antimony, lead, copper, silver, and arsenic. If the manual calls for Lima number two, for example, you can refer to the calculator and see that it has...
