Ok, wow. Lots of comments really fast.
Here is how it worked out.
As 413 stated the stumbling blocks of the process up until now.
By cutting the nails I was then able to pry the bottom of the drum open enough to see the entire inside. I blasted all of it several times. Then heated the adjuster, then blasted it, then heated it, then blasted it. Nothing.
I got out the sawzal and cut the adjuster into two pieces. Didn't damage the drum since I could pry it apart after cutting the nails.
The second the adjuster was not in play the drum just fell off.
However with the adjuster on the upper cylinder was definitely the problem. This would have never released.
