I highly recommend the following lubricants for your 401 project:
1. motor bearings: ZOOM SPOUT TURBINE OIL (http://amzn.to/1IDrnYc)
2. spindle: Mobil Rarus 427 Air Compressor Oil (SAE Grade 30, Viscosity Index 100, Viscosity SUS @ 100 Degrees) This matches the spec required by Oilite for their sintered bronze bearing products and contains no detergents that would clog the pores of the bearings preventing them from self lubricating (http://amzn.to/1TeTyjp)
3. idler wheel bushes: Singer sewing machine oil (http://amzn.to/1dGv1DD)
