Hello all. Let me first say, I've been reading Practical Machinist forums for quite some time now and finally have a question. I think I know the answer from reading a bunch of posts related but I want to make sure I haven't missed anything and I'd appreciate and feedback you might have (good or bad).
I have a Wen 4214 12" benchtop drill press. I believe these are the same as the Jet 12" model with different paint. I've become more and more sensitive to the wobble that I get when drilling. The runout is visible and I'm sick of dealing with it. I took the advice of the various posts here and on other forums and did a few runout measurements. My dial indicator isn't the best but I generally trust it. The video shows the measurements and where I measured.
Here's a summary:
Spindle & Arbor - ~0.0025
Inside Spindle - ~0.000? (Not sure how accurate this measurement is with a regular dial indicator and not a lever type, but I think if it was badly off it would show some movement)
Drill Rod Lower - 0.010
Drill Rod Upper - 0.010
What's the issue. I think it's obvious but I don't want to make an assumption because I'm not an expert.
Also, I don't know what the creaking sound is when I turn the pulley by hand. Have to inspect up there.
Thanks for any help.
