    Default Scraper

    As applied to metal work, what is a scraper? The metal-working forums use the term when they talk about improving old lathes. The inference is that it's a hand tool. None of my machining catalogs list it, making me wonder if it's fictional!

    Here's a scraping class taught by Forrest Addy:

    The hand scraper is a carbide chip brazed onto a file blank or other convenient holder.

    have you used the search function ?

    there have been some imformative posts here and on PM

    a search with Forrest Addy and scraping in it should yield some results.try google as well.

    scrapers can be simple, like an old file ground to shape ,or a piece of carbide brazed onto a steel shank, o fancy like a biax dapra power scraper

    scrapers are comercialy available if you dont want to make yer own

    Look for Engineers Scrapers.


    Hand Scraping is when you make things precisely flat, paralell, ect by checking with a reference (usually a surface plate) and then scraping the metal that needs removal.

    Here's what scraping is all about. Sorry, I don't show a scraper, but I've been using a Biax power scraper on this machine, and I will get back to it eventually.

    That's a hell of a job, Harry - nice work on the tooling.
