hi,
It is nice works. Do you cut that wooden mold using cnc router? I never seen people doing casting details like these here, just keep continue working. I follow your threads here as many other do too.

Thanks asuratman. I don't have a CNC wood router now. All works have been done by hand tools, a electric planer and a electric abrader. So the wood frame is divided to many small pieces to make seperately, and glue them together at last. It's a much more complex work than using a CNC router. I had to measure the scale many times during the work and fix the error.

Casting process normally is far from our DIY works. We prefer to use materials like aluminium, which is easier to get and can get really nice work with machining. but aluminium is too soft for my machine. Another choice is steel material. But the welded structure has very big stress and cause transform to lose accuracy. So, casting iron is still the best choice for a strong and accurate structure.
