Pimping my old Chinese 7X12 Mini-lathe. Everyone modifies these things, as they are basiclly a poorly finished kit set of parts when you buy them. SIEG (Shanghai Industrial Engineerig Group) makes them, but they are sold under dozens of badges. Mine was Artec branded..
This was my first machine tool, and it's been sitting unused in the corner for years. Figured it makes a good victim for learning to scrape in a machine tools ways.
There are a number of videos showing people lapping the ways. Lapping will increase the bearing area, maybe reducing chatter as the ways gernerally have nearly zero contact area as manufactered. Lapping does little or nothing for accuracy, especially if you just lap ways togther, rather than to a known flat standard. It is really just accellerated wear.
Scraping is used to ensure the ways are flat and straight against a known flat standard.
As you will see as the series progresses, not much of this lathe remains original.
