I'm still not sure I buy it. Granted, people have had them break, glass breaks. But I usually fill one 12 oz cheapie plastic water bottle with each batch, the kind with the tiny white cap. I've never even had one of those fail.
A hundred times huh. Caps aside, my understanding of when bottles break, it's usually in a closet or wherever they are stored for fermentation. Hundreds of people have had glass carboys break on them as well, yet hundreds of thousands still use them. It's up to the OP to decide I guess.
Had this tonight...awesome beer in my opinion. Too many 8% IPA's taste like syrup. This has a clean easy drinking appeal that I have to appreciate. Decent hop aroma without the long drawn out bitterness. I'll slam a Pliny with the best of them, but this was a deferent animal. A+ IMO
If I could do it again, I would use the 13/16" strut for the vertical pieces. For a 5 gallon system, I'd bet you could use it for the whole thing. Figure you wouldn't span more than 18-20 inches with it. Head to the hardware store and see if you can bend a 2' piece! In all seriousness...
Hmmm, I guess it might get loud enough to matter, but a mere fish tank is louder. Either way, I would not be afraid to run an empty airlock during fermentation. After a week or so, fill it with vodka, it will be mostly done bubbling by then.
