Ran across this at a ham radio forum - check out his benches and the construction of the tables. Very sturdy!

Mmmhmmm... nice woodworking.

I like his idea for wiring rings made from PVC pipe... similar idea to my own made from coathangers bent into shape with chain-nose pliers. 9 pieces takes about 15 minutes to make, and that included rummaging for ringnose pliers and a coathanger in the closet.
I prefer hooks to rings as they're more convenient when hanging cables; but they do rust where the PVC rings don't, they're conductive/inductive where PVC isn't, and they're entirely hand-made/hand work, so consistency is only as good as your own craftsmanship whereas with the PVC you can knock together jigs in a few minutes to cut/drill uniformly.
But cost of coathangers is essentially $0.00 (and a scowl or three from SWMBO

), so you can put up lots more if needed.
But building TEQ racks into my bench... that's a whole 'nuther level of OCD. To me, the beauty of racks is the fact they can be put on rollers and specific families of gear on different racks for different purposes rolled up to the bench or stowed PRN.
Those are rather sexy.
Well cleaned the 33120A (only the front at the moment). Isopropyl and kitchen towel did the trick. Thanks mnementh. No terry available here. Tried old t-shirt but that was too linty.
Looks pretty tidy now. I fixed the original knob. Turned out that the side of the shaft had snapped off. Rather than glue it, the "fixer" stuck the plastic bit roughly where it was supposed to be and wrapped insulation tape around it (typical EE
). I carefully removed it, glued it and left it for an hour and it's sorted now.
Still will keep the replacement ones as Keysight only had 27 in stock and they are probably the last ones on the planet other than ebay bastards selling them for $50 or something stupid.
Glad I could help. Terry tends to be a bit linty too, but wiping with a dry corner of the towel usually takes most of it away.

One of my fixes for knobs with cracked hubs like you're describing is to glue as you've done, then 2-4 lines of CA on the outside along the long axis of the hub, then slip a length of heat-shrink over it all and hit it with the heat gun. The CA on the outside dries almost instantly, but watch out for CA creeping inside the hub. When it's all dry ( you can test with a Q-Tip swab to be sure ), trim the excess HS tubing off the end and good for another couple decades unless some college kid gets a-hold of it.
