I was curious how the companies that make these knobs actually make them. I guessing they have a machine that makes them. I wonder how many they make an hour? I’m partically interested in round wooden knobs that are about 1 1/2” around.

My guess is they use a CNC machine. Accurate, repeatable, fast.

I would have to look but I think ShopNotes has an article on making knobs on the drill press. Will see if I can find it tonight and let you know which one it is.

I saw an installment of Bob Vila’s show where he was at a spindle manufacturer. They had lathes where one long, heavy duty knife with the entire profile on it was fed automatically into the workpiece, and they turned out the whole thing in a couple of seconds. I envision a similar setup where you’d get a long stack of knobs which would then be fed lengthwise into a combination operation where the knob on the end is cut off, then the sander smooths out the top of the next one, then it advances and cuts that one off, etc. Hundreds an hour.

Couldn’t find the article but found the link to the same article for you. Guess I was just looking through the wrong magazine. Any how here’s the link to do it yourself.
