Deferring once again to your vaster and more better knowledge of things
machine tool-ish, back when this was still America<North in your case>
men were men and ways were hand scraped as the norm... weren't they?
Dale(more scrapper than scraper)
:lol: me too ... I hand scraped the aluminum bed and then cold roll steel for the ways on my Gingery lathe (another guy making one : http://www.backyardmetalcasting.com/lathe1.html). That lathe is now pretty scrap (compared to my Taiwanese and Atlas lathes).
Many serious modern machine tools still rely on hand scraping, although ground ways are also very common.
