Does anyone know about any 1/8 inch needle bearings that way under 10 grams? If so can you send me some infomation about them and where I can get them.
They are widely available from the UK model railways aftermarket components cottage industries. Google Alan Gibson (usual disclaimer) for more information, looking for pinpoint bearings for 26mm long axles. They retail at, typically £3.50 for a packet of 50. The Alan Gibson operation does global mail-order.
It is inadvisable to publish e-mail addresses in a global on-line forum. They are easily harvested by spambots that can bombard the address with unwanted information on non-prescription pharmaceuticals, intimate matters and schemes to get money out out of Nigeria, quickly rendering the address unusable.
