    Scrapers have multi functions.

    • Glue removal after panel glue up, this is were a cabinet scraper is best like this one.
    • Removal of tear out that the thicknesser or hand plane did not remove, using Scraping Plane or this one.
    • Scraper can safe money by reducing the need for sand paper up to 300 grit

    What TS says, Bupton.

    But before you lay into a piece of Hoop pine or similar soft material, be aware that softer woods rarely scrape well. Rule of thumb is, the harder the wood, the better it scrapes (& the more it cooks your fingers, if you are using a card scraper!).

    Most beginners have trouble getting a scraper to make shavings. You should get nive, long ultra-thin shavings with either card scrapers or scraper planes. If you are getting dust, it ain't working properly. The secret is in making a very clean edge (90 degrees for card scrapers, usually around 45 deg for scraper planes) just as you would for any other edge tool. Then you need to turn a burr on a card scraper - I would suggest looking this up on the BB seach function as there have been numerous threads on the process, & there are several ways to do it - take your pick. Burrs on scraper plane blades are optional.

    Using scrapers well is like everything else in this business - it takes practice & perseverance to become good at it. However, it's really worth persevering & mastering them, as they can save you time, not to mention $$s wasted on sandpaper, & your lungs will appreciate a less dusty environment. I have a strong aversion to using sandpaper, & discovering card scrapers many years ago was one of the best things that happened in my woodworking career!

    Cheers,
    IW
