On my Crosley E-15 BE the shafts for the volume control and tuning control are triangular as shown in the attached photos, but the knobs are just circular. Was there an adapter of some sort that allowed these to be firmly mounted? Glue?

I have an E-15 and will check to see what it has…I think it is the same…will let you know tomorrow…

I have a e-15 and mine has round shaft with groves on the outside and a split in the middle of the shaftMarch 14, 2017 at 2:27 pm #8535
im sure you could wet the shaft with vasaline and then put some JB weld in the void in the knob. maybe make a little jig to support it squarely while it sets. let the JB weld kind of half set so it’s gummy so it doesn’t run. then after it’s dry if it doesn’t fit very tight stick a little shim of thin plastic alongside the shaft so you can pull them off.. that’s one radio you need the original knobs for , any others would look funny.
here’s a local one one for 50 bucks in chartreuse. I thought the price seemed ok?

I verified that my E-15 has the same set up as yours…in the past there seemed to be enough friction with this arrangement to hold the knobs in place. Last night when I tried them them came off very easily…maybe it is the dry weather? ( Calgary ). I would try wrapping some tape around the triangular section and see if that helps ( mylar tape perhaps…)
The tuning knob still works but the volume control needs a bit of coaxing to get it to turn on and off…it slips a bit now…

lots of knobs have a very small piece of springy
sheet metal that is easily lost and results in that issue. Im not sure if those knobs used one but maybe?
dryness wont’ affec the fit, they are both metal parts.
its very hard to make two metal parts that fit over each other tight enough to hold and loose enough that you can pull the knobs without setscrews. if the knob was a stretchy material like soft plastic then they might have enough give to have that sort of friction fit but those are metal knobs. the purpose of the little metal tab is so they have some “give” you need the springyness so the knob can be pushed on or pulled off with considerable force. Im wondering if you just lost a little bit from inside the knob and didn’t notice it falling. If it has them they are just little pieces about 3/16″ square. I think I have seen others that are sort of an L shape but still tiny and easy to loose. if you think that could be the case you might find them around your bench. im not near a radio at the moment but someone could check if crosley seemed to use these little metal springs. I think I have seen some that are sort of bent to fit around the inner part of the knob and then across the hole so they fit into the slot in the slotted type of shafts. sort of a G shape
If you understand what I mean Ill stop there but if my explanation doesn’t make sense then perhaps a picture of other knobs that use them would help. If thats the case you can make some from some thin springy metal, maybe a bit cut from a feeler gauge maybe .010″ thick or thereabouts? you can cut that spring steel with a dremil with a little cut disc if you have a dremil.
