Что то я не вкурил-из чего был сделан родной винт? Из гипса чтоли?? 😁😁

First, let me say these guys are badass…. none of this is easy and requires a lot of experience, planning and determination to get done. That said, I’ve got some many damn questions, to wit:
1. How do they know the metallurgy will suffice for the region the ship will be in? For example, steel can become brittle in cold temperatures if it contains too much of this or that or wasn’t heat treated correctly, etc.
2. How do they know whether the screw is properly balanced? Granted, it won’t be spinning at thousands of revolutions per minute but I imagine have an imbalance can cause shaking and vibrations and perhaps reduce the efficiency of the propeller.
3. How much do one of these go for in US equivalent currency? How much do these guys get paid?
