Hi, my trusty old 2000 model VS50 has developed some spindle noise. It is equipped with the 4500 rpm spindle and I think the noise is coming from the lower bearing (closest to tool) however it still feels nice and smooth to turn by hand. The noise is there throughout the rev range but loudest at lower revs..say tapping a hole etc. . I don't have any diagrams for the spindle and am wondering if there are some bearings up the top in the tool grab assemble that I should possible check first or is that all part of the spindle bearing setup?? Thanks
