Installing the Bottom Trim
In David Pye's book,
The Nature and Art of Workmanship, he describes a concept he calls "workmanship of risk." He defines this as "workmanship using any kind of technique or apparatus, in which the quality of the result is not predetermined, but depends on the judgment, dexterity and care which the maker exercises as he works" (
The Nature and Art of Workmanship, p. 4). Every woodworker experiences the angst this can cause at one time or another. Moreover, the risk (of messing up an entire project) only increases the further along we are. It's the source of the thrill that keeps us coming back into our shops, or grief that can cause us to take a long hiatus.
Installing the trim around the desk was one of these angst moments for me. If I miscut a piece as I'm assembling a cabinet, then I will just cut another. No big deal, other than wasting some material. The preparation for installing the trim, however, involves cutting into the desk as it is already assembled. Mistakes get harder to fix -- aka, workmanship of risk. Each corner (six) on the desk is rounded and a notch is cut into each leg for the trim. After the trim is installed, then each corner has to be rounded so it flows evenly around the sides. Like the sign you see when driving in the mountains...
The journey begins by marking where the notch will be cut into the leg. I mark these now while the edge of the leg is still square. However, I only saw the sides of each notch at this time. Fully excavating the notch would leave the bottom corner with little support. It could easily be broken off during the rounding. At this time I marked the curve (white pencil) on each end and penciled lines down the length of each corner as a guide. These aren't the termination of the curve, but rather mark the extent of the starting chamfer as shown in the last image.
The radius of these curves is 1". After making the chamfer I used a #15 (1-1/8" radius) hollow moulding plane to cut the rest. A template made from an old saw blade was used both as a guide to check the curve as well as a scraper to smooth out any high spots.
Once the corners were rounded and sanded I felt safe to finish the notches. These are cut just deep enough to allow the miter on the trim to extend below the curve, and fully hide the back of the joint. I hope this gives you a sense of the "risk". There is no going back from this sort of step.
Finally, ready to fit the trim. The angst level is lower for this. Again, I am adding pieces so worst case is I miscut. The main risk is I only made enough moulding to go around once. A mishap would mean planing another section, so really just time and material. I won't go into a lot of detail. This involves cutting some interesting angles and notches as you work around the base. I began with the back piece, then the two insides (knee well), then outsides and finally the front pieces. Nothing was glued until I had every piece fitting the way I wanted. As for gluing only the corners are glued. Screws hold the rest in place.
I happened to find a box of vintage #10 1-1/4" wood screws at an estate sale. I was thrilled when they told me the price was 75 cents.
After a straight section in the road there were more curves. The final step is to carve the moulding around each corner. The angst level increased again as yet another opportunity to mess up the project loomed. I didn't concern myself with how the moulded edges met since these are carved away. I did want a good miter joint.
There are six corners to round. I find that following the same process is the best way to produce identical results. Also, I chose a back corner as the place to figure out this process. I carved by starting at the top and working down, or from the inside to the outside, however you want to think about it. The grain changes (abruptly) at the miter so you have to work from start to middle on each curve.
The tools used are shown below.
- Direct light for illumination and creating shadows. Contrast (light vs dark) help guide the work.
- 5/16" in-cannel gouge for carving the cove.
- 5/18 sweep for marking the fillet.
- 3/8" firmer chisel to clean up the fillet.
- 1" paring chisel to excavate the fillet and shape the outside curve.
- 7/16 sweep to round over the bullnose.
- Templates for tracing and checking the curves.
- Scrapers and sandpaper for cleanup.
- A handful of shavings for final burnishing.
I'm pleased with the results. The effect is that the trim flows around the base, tracing the curves on the sides. The client (aka, wife) does not like sharp corners, so she is pleased as well -- win-win.
The remaining elements are the drawers and top. I'm still in the design phase on how these will look. My plan is to make some samples to review with the client before deciding.
