With the moulding installed around the arched opening for the dial, there’s one last detail on the hood before moving on to the goose-neck mouldings of the broken-arch pediment. The Egerton tall clock has a small keystone that separates the two pieces of the arched moulding. The keystone is made from solid mahogany, but the face of the piece is a small assembly of veneer. And by small I mean 5/8″ wide at the bottom, 1-1/4″ wide at the top and about 1-1/4″ from top to bottom. That’s not a lot of inlay, so I can easily get that from scrap pieces already on hand. (Check out the photo. You can see a picture of the original clock between the hoods of the two clocks I’m building.)
To get things started, I thought it best to lay out the design to better get a feel for the pieces and steps. That also made it easy to get the sizes of the maple veneer just right, and that made the work go much quicker. After I had the design, I snapped off pieces of the ebony stringing and cut the small pieces of maple from a leftover sheet of shop-made veneer – I’m tired of sanding through the 1/40″- or 1/64″-thick commercial veneer and vow to never purchase it again. To make sure things went as planned, I stuck the pieces to a piece of tape, then checked the size against the actual keystone.
I was now ready to stick the pieces to the keystone. With a thin layer of glue on the keystone, I positioned the veneer and stringing. (Again, I really like the Titebond No-Run, No-Drip Wood Glue.) A neat technique was to lock one leg of my spring clamp into my bench vise, leaving the other leg operable. This allowed me to easily move or reposition the keystone in any way necessary. At this time, I wasn’t concerned about the length of the pieces applied to the workpiece. I didn’t want them to run past the top and bottom, but I also didn’t need them to be perfectly aligned. After everything was placed and slide to its final position (moving the veneer pieces up or down influenced the overall width of the assembly so I could easily match the keystone face), I set the piece aside to allow the glue to dry.
The next step after the glue dried – about 10 minutes – was to saw the top and bottom edges to add the last pieces of ebony stringing. A marking gauge is perfect to scribe lines to which to saw, and I particularly like a Japanese saw for these types of cuts. With the assembly locked in the spring-clamp vise, I sawed the two lines then peeled the waste parts easily off the keystone. A little more glue was added before I position the two last parts to the face of the workpiece. After the glue dried I used a rasp to level and smooth the inlay, then sanded everything smooth with #180-grit Abranet.
The finished keystone is shown in the opening photo. It’s a small piece that adds significantly to the overall look of the clock. And that’s what inlay does, at least to my eye. Also, if you look at the opening photo you can see the first carved rosette that fits at the end of the goose-neck moulding. I ran through three alliterations before arriving at what I think will work. To get a quick look, I stuck the half-finished rosette in place, then stood back to make a decision. So far, so good. But there is more work to be done.
