The art of Hand scraping

The use of a Hand Scraper may be undertaken for two logically distinct purposes.

"Hand Scraping" proper is the process of using a scraper held in the hands to remove small amounts of metal from a precision surface so as to provide an accurate bearing surface to within some tolerance. (The scraper itself may be either manual or powered; the use of a power scraper is still hand scraping because the tool is held in and controlled by the hands.) This kind of hand scraping is the way in which the finest machine slideways have been produced from the early 19th century to the present. The finish it produces may be attractive in its own way, but it is functional process, not a decorative one. This kind of hand scraping is the topic of this present Notebook.

Hand scraping may also be done to produce a decorative finish on a surface. When this is done, it is often termed Frosting or Flaking (q.v.)

A type of hand scraping may also be done for the fitting of plain bearings. Although similar in name, this is in practice a quite different process which employs a different style of distinctively curved scraper.
