Halloween seems to have marked the beginning of the social season this year – at least for my family. While I’ve made good progress on the plinth blocks, I realized tonight that I hadn’t shared much in the past month.

October brought some good progress on the plinth blocks I’ve been working on. Following Matt Bickford’s advice in Mouldings in Practice, I began with dados for the cove.

The coves took a little extra time while I tuned up the No. 12 round. The wedge wasn’t making good contact in the throat mortise, allowing the plane iron to slip in the cut. Without a float in my kit, I used a triangular file to clean up the mortise. The triangular file was a good width, but it cut pretty slowly, so it wasn’t ideal. (I later bought the planemaker’s edge float from Lie-Nielsen with the idea that it would allow me to tune up my wooden planes to a finer degree. I’ll share the results when I’ve had more time to experiment.)
Along with the throat, the iron needed some reshaping. The arc of the iron was a bit too broad, so I needed to regrind slightly. This is not an exact science. All I’m looking for is the iron to emerge uniformly from the mouth. If it looks right and feels right, it’ll do the job.

The tuned-up round follows the dados and results in a nice cove. Note the open cup of coffee. I couldn’t enjoy that with machines!
Spelching is still an issue when planing across grain. For the cove at the top, I chose to make these a bit wide and plane away the torn fibers.
With the four coves complete, I moved on to the v-groove at the bottom of the ogee. When working through my prototype, I discovered that I need to use my skewed rabbet trailing edge down. This helped quite a bit with the reliability of my cut, allowing the plane to follow the reference edge and not overshoot it.

I found, though, that this technique wasn’t quite yielding the crisp surface I wanted to see. The plane iron left a nice, flat surface, but the reference surface was not uniform. I’m not sure whether to attribute this to technique, tool, or unreasonable expectations.
Luckily, a few passes with a heavy shoulder plane cleaned up the reference surface on the first workpiece.
For the remaining grooves, though, I flipped the workpiece around and planed from the opposite approach. Since the upper surface of this v-groove serves as the chamfer for the convex portion of the ogee, it will be worked further with the hollow and doesn’t need to be perfect.
This switch allowed the iron of my rabbet plane to leave the nice crisp surface where I need it.
With the v-grooves complete, it was time to tackle the ogees. A combination of grooves allowed me to waste away the concavities of the ogee. Here, I plowed a groove with my combination plane, and used my rabbet plane for another v-groove to form the transition from concave to convex.

I’m pleased with the results so far. I’ve completed two of the blocks, am nearly finished with the third, and the fourth is awaiting its ogee.
