CASTING & FOUNDARY
Back in 2006, setting out to do our own castings, I constructed an oil powered, tilting crucible furnace, and a sand processing, mulling machine. While the furnace was successful in melting aluminium, it was unable to melt sufficient amounts of iron, so an induction furnace was acquired with a 250Kg and 100Kg crucible, as well as a 450kilowatt generator to power it. At the same time, the sand processing was upgraded.

While some conventional patterns have been acquired, other have been made by my father-in-law. To generate new patterns straight from a computer design, I constructed a CNC 3-D router to cut foam. This also allows for easy reproduction of patterns for lost foam casting (include images). This can be used to cast unconventional shapes that would be impossible otherwise. It has allowed me to construct a 4-inch scale Fowler compound block with compound V ports and full steam jacket, the same as the original.

While we can't compete on 'pound per Kg' iron pored, we can do interesting things with the patterns to ensure their quality. Any inquiries for information and possible pricing, please get in touch.
