ok, so I bought a 6 gallon glass just from the home vintor. The guy was real nice there, and I signed up for a winemaking class to boot.
The rubber stoppers they had were with only a single hole, so I crammed the two pieces of tubing in that single hole, and gobbed it with lots of silicone to make it air tight. I'm waiting for the silicone to cure, then I'll swap out the plastic jug with the glass jug.
Anyone know how long I should wait for the silicone to cure? It's basically a gob a half inch around. I was thinking 24 hours just to be safe, but would 12 hours be enough? It won't be holding water, it just needs to withstand a very small ammount of air pressure.
Either way, I'll post pictures when the thing's done. I've begun sourcing top-off switches, as a backup to the digital timer.
I'm excited to see how it runs on the glass jug. I think it'll start and stop almost immediately, compared to the 1 minute of start/stop times with the plastic jug.
Can anyone think of ways I should test it for accuracy when I'm done? I was thinking of testing it's output at various fill-levels of the jug. Fill it full, and see how long to pump half a liter. test it half full, then three quarter full. I've been wondering if diaphram wear in the air pump would affect the output much, as well. we'll see
