I wanted to make a new buckle for a belt. As a material, I decided to use brass.
Step 1: Making a Mold
I decided to use steel cans and green sand as molds.
Step 2: First and Second Attempts Failed
First two attempts were unsuccessful. First time, brass didn't get into the thinnest part of the mold which was 2 mm thick. During the second attempt the brass temperature was lower than it was demanded.
Step 3: Third Attempt
This time the casting was successful.
Step 4: Finishing
After polishing this belt buckle looks very nice.
