The information and images below depict some of the processes Gabriel Akagawa goes through to make Refrain iron railroad tracks. The lost-wax casting process is employed.
Frequently asked question: ‘Why only cast eight tracks on a tree?’
Answer: The weight and scale of the ceramic shell molds (6.5 pounds) and metal castings (15 pounds iron) allow for easier handling and transportation. Akagawa often has time/family restrictions to attend one day of an iron pour. Smaller trees allow for easier pre-heating of molds, easier setup and cleanup, faster cooling of the metal, and less emotional impact if a mold fails.
