I emailed the guy from craigs list, he called me tonight.
For $20 I can get a sealed barrel in good condition + $10 for him to do a perfect cut around the bead.
For $50 I can get a barrel with removable lid.
I am going to go pick it up tomorrow afternoon and bring the weber lid with me.
I am going to see how it fits if I flip the barrel, if that fits good then I will get him to remove the bottom not the top.
Apparently the barrels are bare metal inside and not lined
