And the latest is that the Variator now seems to work: https://www.youtube.com/watch?v=0uGYNYR-6SA But I have made a bracket to not use it: https://picasaweb.google.com/108164504656404380542/Holbrook#6242003069535317714 The spindle now spins to 2500 but still not the full 3000. There is a good chance that the spindle oil pump was broken for long enough for damage to occur to the head bearings. I have to admit that they do rumble a bit. I will get the lathe fully functional first, then decide on head bearings. Bearings are listed as 387/382B Which are available and not as frightening as I feared: http://simplybearings.co.uk/shop/p40679/Major-Brand-387/382B-Imperial-Taper-Roller-Bearing-Flanged-Cup-and-Cone-Set-2.25x3.8125x0.8268-inch/product_info.html Though if I _really_ like the lathe, perhaps I will get carried away: http://simplybearings.co.uk/shop/Taper-Roller-Bearings-Super-Precision-Taper-Roller-Bearings-Flanged-Cup-Type-Taper-Roller-Bearings/c1_5458_5461/p20036435/Gamet-110057X/110096XC-Super-Precision-Tapered-Roller-Bearing-Flanged-Cup-Type-57.15x96.838x29.5mm/product_info.html I don't know how much those are, but 55/100mm ones are £216 each. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
