Above showing the table saw set up for ripping stock to width, and the hold downs, more here. Next, the shaping of the stock into moldings. On the molding pictured, I will first mill the rabbet, as once the molding is shaped, there will be little to reference against.
Above, I'm using a small, wooden scrub plane, to quickly rough out the shape of the molding. That's an entirely serviceable antique I'm using. Scrub planes have a convex blade and are designed for fast removal of waste.
Here, the shape is being refined using a small block plane. In both pictures above, I'm using one or more of my fingers as either a fence or a guide, to hold the plane steady, and cutting the same angle for the full length of the stick. This will be followed by a random orbit sander with a flexible pad, to further refine the shape.
For this molding, I have some photos to view, but no actual dimensions, so I'm hand shaping it, eyeballing it until it feels right. A fairly quick process, but done over a few days to allow for "tweaking" the shape. Leaving it, then looking with fresh eyes, is an enormous help in producing a satisfactory shape. Changing the lighting, and viewing position, looking at it in a mirror, or on it's side, are variations of the need for a fresh perspective, time away just one of those. The result was accurate molding legs, that when mitered and joined were as close as machined moldings would have been.
