Help needed re Chinese lathe saddle adjustment

[TomG]

Something you may want to try to get it serviceable. If you blue the ways and run the saddle down until it binds up, you should be able to see where the blue is rubbed off. If you then scrape those spots, it should travel a bit farther next time. I doubt the saddle has any wear on it, so essentially you would be using it as your reference to straighten out the ways.
