Outrunner Spindle Parts?

[Tenson]

The standard 200watt motor that is blown only uses 1 bearing at each end... but then it isn't necessarily a good item to copy!

Edited to add... so what sort of bearings do I need to get? It would be nice to use ones with an outside diameter that fits a standard drill, so would 8mm ID x 12mm OD be suitable?

i would assume that those two bearings are angular contact bearings or its a cheap spindle with deap groove bearings
a typical hand wood router would have bearings that reflect the lack of need for exotic bearing setups
a dremmel tool would be the same... very good at what its designed for, attach it to a cnc router and the bearing slop may well show (dependant on the job your asking it to do)

i lost bearing tension on one of my diy spindles and it took me ages to work out why i was getting a crap finish whilst fly cutting acetal
the play was tiny... the effect was an unusable finish
your cnc may be capable of extreme accuracy and have splendid stability... it would be a shame to throw that away on sloppy spindle bearings
that does not mean you shouldnt make the simplified spindle
just bear in mind the implications :)
