Sooner or later, most woodworking sites and blogs have some sort of post on scrapers. Rather than duplicate what others have demonstrated in the care, feeding, use, and maintenance of scrapers. I’d like to point out that they produce much less dust than sanders – that’s a hell of a significant point when you have a confined shop and allergies. They also can give you a crisper, almost cut, finish. If you look at the picture of the bowl with all the shavings, you’ll notice that they are shavings, not dust. A properly sharpened scraper produces shavings.
In this instance, the birch short had been around the shop for about ten years. At some point, I had outlined a bowl shape on it. Last week I moved it from the maybe soon bucket to the on schedule bucket. A few days ago, I rough shaped the outer contours and took some latex caulk to the bottom. I used the bead of caulk to paste a pine cleat to the base; when I no longer need to secure the bowl in a vice or a clamp, the caulk will quickly release with some alcohol and a putty knife. Cleaning up the caulk is easy with the scraper. In the meantime, It will take all the rough handling I can give it while shaping the bowl.
Today, I needed a break from some other work, so I roughed out the inside of the bowl. A few years ago I would have done all of this with hand gouges. These days I use a variety of Arbortech ball gouges and Kuztall discs to rough out the bowl. Warning: these tools require a dust mask, face shield, glasses, hearing protection, and heavy-duty gloves. Not used with care, they will cause severe industrial injuries. But, in hardwood like cherry, maple or birch, they save labor on the rough out. I like to use these tools out of doors. They produce prodigious amounts of chips.
After roughing out, I used a relatively flat gouge to clean up the shape to the proportions I wanted. At this point, you might be tempted to get the sander out, and I won’t tell you that it’s wrong to do. It comes down to work style.
I reached for my scrapers and put in about forty-five minutes, smoothing out the inside of the bowl. When I thought I liked the result, I applied a bit of Turps to the wood and observed all the holidays, dings, and other imperfections I did not see while the bowl was dry. Another test is to close your eyes and run your fingers around in the bowl. If you don’t like the feel of a bump or a small divot, chances are that the client might not either. Closing your eyes to see is a much underutilized free tool. Tomorrow I’ll go back with a pencil and highlight the areas I need to fix before I start to work on the outside.
This is a carved bowl, not one turned on the lathe. I tend to leave more meat on the sides and bottom of these. My goal is not to make a fragile walled vessel, but one which has some substance to it
My final picture shows a selection of scrapers and scraper tuning tools. Not shown are my collection of little homemade scrapers; they are pretty easy to make to any pattern you desire. The scrapers pictured, and more, are available from a host of suppliers for a wide variety of prices. If you don’t have any, I advise that you buy a basic set from a reputable dealer, like Lee Valley or Woodcraft Supply. Most of the people who are disappointed in scrapers have not put the time in on learning how to set them up. I know, because for years I was one of them.
