SteelQuad: Steel Quality Sensing Device (week 8)

2014-07-08T06:27:38Z

I redesigned my mould. The cylindrical type of mould can be easily made but the steel would be placed vertically and I have to make it stable. Therefore it is prone to error when the steel is not centered. I have redesigned it to be a rectangular blo...(read more)
