I tore up a rear wheel bearing dust cover when the cone nut vibrated loose (or maybe cover vibrated loose tearing up the cone nut surface in the process). The local bike shops don't carry those covers (I got a cone nut replacement). Does one need fabricate their own cover to avoid replacing the entire wheel? Is there some obscure place that sells this rarely replaced part?
If fabrication is the only remedy, how does one usually fabricate a replacement-bottle cap liner drilled and cut down, milk jug cap, soda can bottom, or just get another new/used hub and rob peter to pay paul?

You didn't specify the brand of hub you have, but if it's
Campy or Shimano you can buy the 'small' parts for those
hubs. If you know which hub you have, or if not take the
rear wheel to your LBS. In any case Campy and Shimano hub
small parts can be ordered through QBP (Quality Bike Parts)
and aren't terribly expensive, and are easy to get. -
One thing I've done is to cover the balls with grease to
make a smooth surface, keeping the hub recess (where the
cover sits) dry, then gently apply silicone RTV (bathtub
caulk) to act as a cover. Works fine, although it has to be
redone next time you clean and pack the bearing.meb said:

Went to five shops, the 3rd had some but in the wrong size, the fifth had a used one that was the right size they gave me free. It’s is such a rarely replaced part that it isn’t generally listed as a for sale item usually you give up and replace or cannibalize another hub/wheel-preferably discarded if available (one shop that didn’t have any told me that since it’s not a for sale item, the manufacturer would probably mail that cover to me free if I called them).
I was considering Epoxy or Silicone as an adhesive rather than a cover body. Your suggestion got me thinking. If it ever comes up again, what might work better would be to use a thin disc cut sheet over the bearings, hole punched for the axle, and then coat the outside of the sheet with silicone as a dust barrier with the sheet serving as a temporary barrier to keep the silicone out of the bearings, and then adhere the silicone disc (cured or curing) to the hub. -
search DIY in tech. the flea market plus o rings and
rectangular 1/4x1" poly bottle shims under the new cover
shud fix it.
