I believe either Bison or Buck or maybe both make a lube for their chucks . Jim I have been very happy with my Sanou chuck for many years now . Just make sure the jaws & slots are numbered before dissembling . I made that mistake with my first chuck many years back . It took a lot longer to put back together than it took to take apart . Kicked myself in the ass a couple of times for that one . good luck animal

I used to rebuild motorcycles so I have muffin trays to keep track of parts that shouldn't be marked, like engine valves, and a set of dollar store nail polish in the electronic color codes for numbering and marking polarity. A red '+' on a black battery case shows up much better on a white background. It's fun to see the clerk's reaction when I ask for help with the nail polish, they are very helpful after getting over their initial negativity.
I have number punches for soft or thin metal, a broken tap reground to a punch for dotting steel, to avoid damaging my good center and number punches, and a Dremel cutoff wheel to mark hard steel with Roman numerals which consist of straight lines up to C. The acid pen I tried expands into a blur.
The real question is if anyone can recommend from experience an effective and readily available lubricant that doesn't hold dust or chips, possibly a bicycle chain lube or the Liquid Wrench dry lube that the LeBlond video suggests. Someone suggested putting a cardboard box over the chuck before spinning it at max speed to expel the grease or oil. I'd retract the jaws into the chuck body first to avoid a dramatic display of confetti.
