Title: Where can I find knobs like this?

I've spent hours looking for these knobs. I've checked all the sources I know of, and haven't found anything. I'm guessing that I'm not searching for the right thing, but I don't know what I should call them. I've tried "pot knob", "dimple knob", "encoder wheel", and everything in between.

I can occasionally find a used one for sale, but they're expensive, and I'd like somewhat of a selection. I'd like one to put on my logic analyzer, but I just can't seem to find them.

If you could lend any help, I would greatly appreciate it. I have searched the forum, but may have missed a thread. If I left anything out of my post, just let me know.

Thanks.

They're also called "spinner knobs" but you have to wade through a lot of knobs by the same name that are meant to attach to a car's steering wheel.

Here in Canada, Google thinks it looks like a flywheel ring gear.

All you have to do is type " potentiometer knob " in google images.

Via your posts, I've been able to find a valid knob. Thank you much, and I look forward to seeing you around the community.

Thanks.

I shudder to think what you will find if you do an image search on Google for "knobs"" :-DD

Try searching for "amateur radio VFO knob".

*edit* -- I should read everything before I post.  Two posts before mine I see you found what you were looking for.  Regardless, a "VFO knob" should bring up all kinds of dimpled knobs with the finger-dimple spinner.

Like these:

Nothing too bad on the first 2 long pages of results, with SS off.
