Hello! I have a late 70’s – 80’s Guardian drillpress that came with a house I moved into last year. It’s has a noticeable wobble when running. I believe it’s only in the chuck and not the spindle itself. I only plan to use this drill for hobby wood projects, so it doesn’t have to be perfect. But, right now it’s somewhat unusable. Do you all have any advice as to remove the chuck? I believe it’s part of the chuck and pressed in. It’s stuck and I can’t get it to drop out for the live of me. 

Thanks in advance!
