Alright, first off, you can go here
and check out Bill's instructions.
So, the end of the can is kind of two pieces put together, so using a sawzall or something will get you a different result than what I did, but similar.
As you can see from the picture below I used a hack saw and cut through just the outer shell all the way around just behind the weld.
After you do that, the two parts can be pulled apart, or pried apart using a screw driver.
All of the innards are not connected to the other end of the pipe, just to the one out pipe. I wrapped the part I have in my hand below in a towel, then put it in a vice and pulled the shell of the can off of the innards before I cut the tube.
The screen is wrapped in packing, and very stiff to pull out, but as long as your can is like mine was you just have to pull really hard.
Below is a picture of the part of the back piece that buts up against the back (cut part) of the can. Everything to the left of my fingernail is outside, everything else is inside.
The long, cut tube is the one that attaches the innards to the end cap. The screen is tack welded to the cap in about 4 places, I just used a screw driver and broke the welds to get it off.
The reason I did all of this was so I could make a storage can, but I think I am going to play with a different setup now that I spend the time to figure this out.
Hope this helps.
