Jet JDP-17F pillar drill problems – diagnostics?

A while back I bought the above floor-standing drill from Axminster. It was never entirely satisfactory because of excessive vibration – not just the tinny rattle from the flimsy guard on the top, the whole machine shakes and makes a horrible noise. It actually drills accurately enough, but I hate using it because it sounds like it's destroying itself. I'd like to sort this out rather than scrapping the machine. Any ideas where to look? I suspect the intermediate pulley which seems to have a flimsy mounting….I really don't need 15 speeds so no great loss if I could go direct from the drive to the spindle..

I bought a secondhand drill like this. It had been used but was in very good order. I too found that the intermediate bearing seemed a bit "shaky". How ever on loosening the various motor clamps/ belt tightening doo-dahs, greasing them then re tightening, it ran fine. I feel as though something was tightened against some swarf and not against its pillar/nut etc. The whole table rise and fall mechanism was also attended too, it almost works now, but wonderful value.

Also check that all 3 pulleys are lined up properly. Belts running slightly offline can cause vibrations
