An update on these:
The range of rotation is ~300 degrees with clutched stops at the ends. They take a 6 mm shaft, so drilling out is needed to accommodate 1/4" shafts. They are intended for single turn pots. So you only get 0-60 in 180 degrees. However, with laser engravers common, a custom dial shouldn't be a problem. So for anyone who is fond of pure analog radios they are a steal.
I've attached one to an existing breadboard variable and also showed the bracket which is included with an air trimmer in position, but not attached. The air trimmer shaft just isn't long enough.
There are a slew of other sellers, possibly at better prices. It changes constantly.
This is all I have to say on this thread unless someone has a question. I thought I should give people a heads up that these were available at such reasonable prices.
Have Fun!
