I’m shopping for my first scraper. My current project is a set of bandsaw boxes that are oval in shape. They range from 3” to 6” high. I don’t know how to express what their radius is, but I would say “gentle to moderate”. The original ovals on the patterns were 3” x 5” for the smallest one and 7” x 11” for the largest one.

I want to scrape them, not sand them, because I plan to dye them to bring out the figure and the finishing recipe I am following recommends scraping.

Scraping the centers should be quite straightforward, but I’m wondering whether I’ll run into trouble on the ends. I’m assuming I want a standard, rectangular scraper. Would a super thin, super flexible one be what I want for getting around the ends of the ovals?

The wood is maple.

I think scraping is going to be more difficult than sanding in this case, since you’re trying to follow the curve of the box with a thin straight edge of metal, bowed to only contact a small surface area. If you’re concerned with the sanding not leaving a nice cut fiber, you could do 90% of the work sanding, then follow up with a scraper.

If I understand what you’re describe though, than yes, I’d use a plain rectangular scraper, unless you can find one that will fit the contour of the oval and scrape very lightly cross-grain.

Try using a single-edge razor blade. I scrape all the time with these. When they become dull, toss it away and get another one. Cost is about $5 per box of 100 ( 5 cents each) and sometimes you can get a better deal than that. I have done entire cabinets with these.

How do you hold them (other than “very carefully”...)?

I have this set from LV and so far it served me very well. From very hard to very flexible

Broken glass makes a good scraper, and it’s very cheap—as long as you aren’t buying new panes of glass to do this. Window class is the right kind. Put an old pane in a bag and smack it just enough to break it into pieces. You’ll get both concave and convex edges. Not every edge will be sharp, and the sharp edges will dull after some use. Though I suppose some will feel this is dangerous, I have rarely cut myself, and then minimally. If it concerns you, put masking tape on the edges you won’t be using.

Sometimes a straight edge will be sharp, but don’t count on it. Even for flat surfaces, you can get a more aggressive cut with a slightly convex edge.

Have your say...
