I’ve decided to give card scrapers a try, the look like they would be extremely useful and give a very nice finish.
so this brings me to my question. I’m sitting here with the lee valley catalog and I’m not sure which one I need. The sizes are .4mm .6mm .8mm and 1mm. It is mentioned in the catalog that the 1mm is suitable for paint removal, so I assume this one would be too thick for fine woodwork. I would like to do both some heavier scraping, and some finer finish scraping as well. Will an in between size work well for both jobs or should I get the .8 and .4 and use the different ones for the different jobs?

I have a “standard” one from some random brand and it’s 0.8. It does everything I need it to do so I don’t think you need to bother with more than one unless you reeaaaally get into scraping.

You will also need a mill file (10 in.) and a burnisher, as scraping edges need to be refreshed often. There are lots of ways to sharpen and maintain the edge on scrapers, but almost every method needs the file, some type of abrasive (sandpaper, diamond stone, etc.), and a burnisher.

Strangely enough, I bought a card scraper yesterday too – I was amazed to see it in the local DIY shop so I snapped it up.

Anyways – I’ve looked at some videos, and I’m a bit confused about the “burnisher” – the last video I looked at it looked like a screwdriver. Since I don’t have much hope of finding the “official” thing – will a screwdriver do? Or what might be better?

In My experience, the burnisher is a very hard piece of steel. and can be slid along the edge of the scraper to roll the edge. If careful, I have used a file tong, and worked the edge with that. Cards can be made from an old saw by filing the teeth down, and filing the edge very straight. I have had good success by doing that. A sale, can usually find an old saw laying around, and the handle used for another project , or a replacement on Your own saw.

Your burnisher can be a screwdriver or a router bit or any piece of steel that is polished and a harder metal than your card scraper.

Just FYI to LJ’s, it looks like Woodcraft is going to have their basic set of scrapers available on Black Friday for half price…as long as supplies last. I think the price is $7.99 for a set that normally runs $15.99. I share this information hoping you won’t get there before I do.

Regarding scraper sharpening, some fellow, in a video, showed his method. He simply ran his scraper across a mill file and didn’t bother with the burnisher. I tried it and it works just fine. You don’t need a lot of pressure on the scraper, just run it along the file at 90 deg. until you can feel a curl forming.
The curl doesn’t last quite as long but, it only takes 4 swipes over the file to restore the curl.
When I used to burnish, I used an old round butcher knife sharpener.

alright looks like I’m ordering the .8, from the videos I had seen it seemed like each one is quite versatile. I’m very exciting now, I can’t wait to get my first card and give this a try, especially since I just tore apart a skid and got a nice pile of maple I can’t wait to use!

The round shaft of a lathe cutting tool works great for burnishing. I use the shaft of my bowl gouge.

Alright, I got impatient and decided I could make a scraper myself. So I took a hand saw I don’t ever use and cut a 2”x6” chunk out of it with the reciprocating saw. After grinding it straight and filing it I was able to take some fine shavings and get some saw dust as well, but nothing more, and fairly inconsistently. I attempted to the shaft of a router bit as a burnisher but with very limited results. Is my problem just technique, equipment, or should I just be patient and order one?

Gedubs thanks for the heads up on the scrapers. I will be at the store bright and early and will most likely get one before you since I live in Delaware. Our Sun will be up before yours :)
