I have a Craftsman benchtop drill press/drum sander unit I got used off of CL some time ago. I haven't used it a lot, but part of that reason is because it seems to have a lot of runout (visible). I actually got the manual with the drill press, and it stated to re-mount the chuck first, and if that doesn't work I need to replace the bearings (I think--don't have the manual in front of me).
It's the same looking model as Grizzly's drill press/sander, and although I'd like to have a nicer one for some of their features, I don't really want to spend the money on a new one (and this one says "made in the USA with US and Chinese parts").
So, how hard is it to find bearing parts, and how hard is it to replace in a small benchtop drill press? Are there special tools required? I haven't tried to remount the chuck, and I will try that first (it's bolted in instead of press-fit). If that doesn't work, is it worth spending the money and effort in fixing?
