the guts of a magchuck

Howdy everyone!
today we're tearing into a permanent magnet magchuck i recently picked up from a fellow machinist and since it was not acting what seemed to be in line with other magchucks i've seen showcased, it seemed prudent to open it up and do a little service work to it.
i do apologize for some of the wonky views that are out of frame in one segment of the video. talk about having a blonde moment... doh!!
since i've never seen the internal workings of a magchuck i thought it might be interesting to others as to how they look and in this instance are set up inside.
