Hi everyone,
A couple years ago I bought a big honkin' drill press, a Porter Cable 15" PCB660DP. It was more than I needed, but I figured what the heck, maybe one day I'll be glad for the size.
I assembled it right away but it mostly sat unused for the last two years or so, only occasionally being used for some small job.
In the last month or two I've started using it more, and I've noticed that no matter what bit I use, I'm getting a pronounced wobble or run-out at the end of the bit. Maybe as much as 2 mm or so. It's not bent bits, since I see this with multiple bits, and if I lay my finger on the spinning chuck, I feel a pulse there as it spins.
Though I felt I followed the instructions properly during assembly, it's quite possible I did something wrong, and I want to fix it. I'm just not enough of a big tool guy to know where to start.
I do have the instructions; the relevant page where I assembled the chuck onto the spindle arbor is page 13. I'm just not sure what I could have screwed up that would cause the wobble, or how exactly to fix it.
Before I attempt removing the chuck, and possibly damaging things in the bargain, I figured I would check with the tool gurus here and leverage your experience. I don't even know how to remove the chuck, as it's been hammered into place with a mallet. Presumably downward force on it, but I'm not sure exactly how to do it.
Guys, please take pity on me and help me sort this out!
