I have an old machine with a QC chuck that I'm trying to get up and running after sitting for a couple of years.
Everything seems to work OK except the QC chuck. It's stuck.
It turns and cuts fine but the bit won't release. I try to pull up on the retaining ring and nothing happens. I've even tried using a Crescent wrench set to just smaller than the diameter of the ring and propped up with a block for leverage. No luck.
It's been sprayed with WD40 in every crack, no luck.
Any suggestions?
