Never underestimate what you can get by dismantling:
CD drives
hard drives
3.5" floopy drives
knackered power drills

They all give you bearings. The peripherals give low power
bearings, but good for most experimentation. Also, stainless
steel shafts, discs etc.

Scanners give you more stuff, 12" SS shafts.

Hard drives also give some neodymium magnets, mumetal shielding.
and a beautiful half inch coil.

microwave ovens give annular ceramic magnets and masses of
enamelled copper wire if you cut through the big tr5ansformer
with an angle grinder.
