This video explores multiple techniques for making wooden knobs without using a lathe. It was a dense one. There were far more details than could be included in the quarter-hour. If you plan on doing this, I suggest you watch the video closely for tips. For example, those six hex-bolts on magnets weren't just for visual spice; those were also super-effective knob finishing stands. The overall process is pretty nice. It's nowhere near as difficult or time-consuming as it might look. In fact, it would be reasonable to plan on batching out enough cabinet knobs for an entire kitchen in one easy shop day.

A few more tips:
If your knobs aren't spinning true on the drill, and you just don't know why, the culprit(s) may surprise you. One likely cause of error is the threaded rod itself. Cut the piece as short as it can conveniently be, and check its straightness by rolling it on glass. Another cause of wobble might be the coupler nut. Most of them are way out of alignment with respect to having a bore that's parallel to its sides. Check your jigs systematically for where they are introducing error, and then replace the part that's mostly causing the problem. It's usually not the knob—and even when it is, you won't be able to tell in the finished product.

Finish:
Most of those featured here were finished with a clear gloss Polyurethane, which is highly recommended. The Walnut and Maple knobs in the opening shot had been finished with a pre-mix Shellac.
