Hey guys, it’s casting challenge time again. This time it’s a Tri-Metal challenge, taking
three metals and combining them into something. I decided to make this challenge about precision
casting. Is it possible to cast three accurate pieces at home?
For this exercise I turned to Fusion 360 and this is what I designed. Yup, it’s a jigsaw
puzzle, a triangle with three interlocking pieces – each of a different metal. If that’s
not precision casting, I don’t know what is.
One of my viewers said to me last week that in Poland Aluminium Bronze is called Bronzal.
I really like that name. It’s much less of a mouthful.
These rough edges are called flash lines. They’re caused by cracks in the plaster.
Look at the state of that! That’s it. I’ve had enough of this plaster. Every time I use
it, it seems to blow out one end or the other. This brand may work well with perforated flasks,
but I’m struggling with my solid flasks. I’m going but to my usual brand.
That’s it for now guys. Take care and thanks for watching.
