I have a delta benchtop drill press -- works great for the $200 cost.
Lately I noticed that there was a lot of run out on the drill bits. Working
my way upward I eventually removed the chuck (at Jt33) and found the
spindle? had little to no runout. However I noticed that the taper had two
grooves around the circumference and when I looked into the Chuck there were
corresponding scratch marks there as well. So what to do -- my
recollection is that the taper should be clean and smooth and the chuck is
held on by a friction fit. At present the taper on the spindle has rough
spots so I figured a bit of sanding while the drill press is running will
take care of that -- I figure it is cheaper and easier to buy a new chuck
than to try to polish up the inside part but when I went on line it seems
that spindles and chucks are sold in sets.

Soooo the question is should I get a set, remove the spindle and replace the
whole shebang ? or are all the tapers the same and with a little sanding /
polishing make the spindle smooth again and use a new chuck ? Anyplace
better than another to buy the parts ? Would it be best to just order from
delta ?

Suggestions appreciated

Cheers
