He Du.
It is very hard to find pattern makers, very few in the whole world. My father owned a foundry in China. We would sit at a long bench and do everything by hand, like long ago. Making patterns is a very special trade. You need to know how the foundry uses the pattern to make the casting and how the machine shop will finish the part after the foundry. So you have to know two trades. I have a lot of fun here. I get to see how the parts fit into the cable car, so I can make a judgment and make things better. For example, they changed the frame on the roof and the post holder has to follow the curve. So I made a new pattern to follow the new curve. I felt so proud when the casting came back from the foundry, and I got to see it fit on the cable car.
