I've seen a chemical supply shop that sells the two-hole stopper, so that's not a problem getting (although I can't remember the URL of the site... I hope I remember when I get around to building this thing, any help?). What I can't find are metal bowls with stems long enough to go to near the bottom of a bottle, as the ones in the GC link do. I basically just need a long stem, but all the bowls in the local shops are glass, and thus have a shorter stem.
Any ideas? Should I just try to find a piece of threaded aluminium pipe? I've made long-stemed bowls from stuff around the house but they literally rust away (no stainless steel pipes laying around, apparently).
Also, as an aside, does anyone know of a cheap (as in, I don't need to order in bulk) chemical supply shop? What I need is the various flasks they use. My job takes me around to chem labs and damn, I've seen stuff that *screams* "Make a bong out of me!". Shit, I'm pretty sure some of them are intentionally stored to look like bongs, hell, I once saw one that was bong shaped and even had a glass-on-glass stem and bowl. Perfect fucking bong. I'd steal that shit but if I touched most of the stuff from these labs I'd probably die. But 100% pyrex and everything. I mean like I seriously think some bongs are just pyrex glass from lab stores, because the joints for them and everything is *exactly* the same. Just bongs say "ROOR" and not "PYREX 500ML" So I'm trying to find a place that sells that glassware, but I don't want to ask around work even though they probably know what I'm thinking about when I'm staring at some piece that would make a perfect multi-chambered all-glass on glass bong but I can't take it
