My brother, a master craftsman on my custom-home building crew, started out as a boat builder. He learned a scribing technique that involves something called a “joggle stick.” It looks similar to an old-school handsaw blade—though when you lay eyes on one for the first time, you might think it’s something Sasquatch would use as a back scratcher. You it use to plot a series of points on the material you’re scribing. It’s the perfect tool for fitting complicated shapes and round curves, like countertops into the hull of a boat. It’s not that practical, however, for scribing the kick or side panel on a base cabinet in a house. For that, we employ a number of strategies, depending on whether we’re retrofitting cabinets in an existing house with a finished floor or building in new construction before the floors go in.
This particular job was part of a large renovation we’ve been working on for months in an immaculately maintained historic Victorian in upstate New York. The cabinets were in good shape but weren’t installed well (the maple countertop was 1/2 inch out of level in 8 feet).
The owner wanted us to relocate a single large base cabinet in what will become a utility room, making this is a good place to illustrate some of our basic scribing techniques. Some may think them a little crude—but I can assure you that they are both efficient and effective for a skilled craftsman; doing good work doesn’t have to be elaborate or sexy. Most of the time, only a small block of wood (the fat part of a shim works well) and either a circular saw or a belt sander are all that we need. I’m sure some hipster “maker” could produce a titanium alternative, but it’s not needed. For long, straight tapers on end panels or face-frame stiles where the finished edge won’t be seen (wainscot will cover it on this job), we use a circular saw.
When the base will sit on a finished floor, especially if the floor is in an older home, we’ve found that a belt sander can’t be beat for wasting away material on the cabinet bottom. We like that it provides a good amount of control and can follow even slight variations (like subtle waves) in the floor. The sander also removes a significant amount of material quickly, so it’s fast. The circular saw and belt sander were the perfect tools for this job; we could maintain high quality and accuracy but still work quickly without a lot of fuss.
Most of the time, we install custom-built cabinets in new custom homes in which our framers leave us level and plumb planes to work from and to. Scribing is fairly minimal on those jobs (we pay our framers well). When setting cabinets before the flooring will go in, we simply shim level and plumb, and then spend the most time carefully scribing where a finished edge will be visible.
Scribing face frames and end panels. To mark the scribe line, we like to use a set of dividers because they scratch the surface with a distinct line, making for an accurate scribe. General Tools (generaltools.com) and Starrett (starrett.com) make good ones. We don’t often use a traditional compass and pencil if we need a very fine, precise scribe line.
We also do a fair amount of renovation and remodels on homes built in the late 1800s and early 1900s—a prevalent house type in our area. The new kitchens that we install in these older homes are often substantial in scope and call for custom-built cabinets. On those jobs, I check the floors and walls for level and plumb before I start building the cabinets (or order them, if they are coming from elsewhere), so that I can add enough “scribe” material to the toekick height and the panel and face-frame stiles. I don’t get carried away here—I just give myself a fair amount of extra material (usually about 1/2 inch, sometimes 3/4 inch) to ensure, for instance, that the kick isn’t too small once we level the base cabinets. I do the same on face-frame and panel stiles so that the smallest amount left will match the width of the matching stile.
