Utterly fantastic work! I recognize a LOT of the parts you've used, because they are in my parts-boxes, too. But this pic... (assuming I piced the right one) Ok, I know soft-drink lids for the top and bottom, but what is the bulbous container you used for the main body of this container? I saw you've used several of them on their sides in another pic or two, as well. This is a great-looking pressure container that I would love to replicate...
And your "random machinery" bits are genius. I have NO idea what most of those parts are! Perfect!
