    Sharpen a Card Scraper

    Ok, I have seen it in too many posts. How do you sharpen a card scraper? I picked some up today at Woodcraft, they look fine to my untrained eye.

    I hate to take the lazy man's way out... but I could type a LOT of words here, or I could just do this:

    I skip the stone step, though... and I just use a stick burnisher - no fancy stuff.

    EDIT: This one provides better explanation, although it's aimed more at luthiers' scrapers:

    Steve,

    There are a few videos on YouTube that show some ways to sharpen card scrapers.

    If you subscribe, Bob Van Dyke takes it to the next level here:
    http://www.finewoodworking.com/subsc....aspx?id=29750

    Bob goes well beyond what I do but has some of the best advice on scrapers I've heard; "I'm not gonna get it perfect but, you need to realize; that's OK. It'll work just fine".

    He also shows some good tips on methods of use here:
    http://www.finewoodworking.com/subsc....aspx?id=29751

    I jointed a block of hardwood square and cut a kerf in it to hold a mill file. I clamp the scraper in the vice and use the block as a guide to use the file. I do stone the faces and edges but a 600 grit diamond plate works for me. I happened to get the Veritas variable burnisher as a gift but the old car valve I used to use did as well ;-)

    I watched the videos, read the articles and went down to the Dungeon for just a little while and had some success.............

    Still not as nice as I'd like the finish cut is not great, but better than I had been doing for sure.

    With the loupe I can really see that there is a burr there, but it is very jagged, so I think I have to go past the #1000 diamond stone I have and use the ceramic water stones, up to #10,000, that should do the trick in getting a smoother, sharper burr.

    Cheers!

    The shavings on the left I got tonight, the ones on the right are from last night, and the real proof was the surface of the wood was a lot smoother this time around!

    I still might invest in some of the LV jigs, they really do seem fool proof, and they are not expensive, so they might make good Christmas gifts etc.

    Thanks for the info guys, this was a really good experiment.

    Cheers!

    Stu, you are making me look bad. I haven't even started sharpening mine yet.
