The gear teeth showed rust and were kinda rough, again, you cannot blame the Chinese manufacturers. It is at the request of those companies who go to China, make a deal for a low cost machine in order to make a profit for their business.
I know from experience with Chinese turbines that they are entirely capable of fine finish work, to exact dimensions.
I was thinking that with the amount of my own labor, that if these machines had been finished, that the end cost to us, would be at least another $800 – $ 1200, by the retailer, which would put these rigs a little out of reach for most hobbyist.
Here it is disassembled and ready for the spa day. The snap rings used are also very cheap, when you remove them they stay deformed, so I’ll have to search for some proper hardened steel clips..
