|These are the drive wheels which are 80 inches in diameter.|
This is what my model looks like in Solidworks. It is not the finished wheel only an attempt at modeling.
This is the tool path generated with HSMworks in Solidworks.
These are models machined in Precision Board on my cnc router.
Next, I will model a wheel like the real one and machine it out of polystyrene foam for the lost foam casting process. I will make it 10 inches in dia. for the scale of the live steam Loco. I will cast it in grey iron. I will post pictures of the process. Also I will have pictures of modeling a new cupola for melting grey iron
