Closed Transfer in Glass Carboy- Am I thinking about this right?

Can we get back to the realm of the psi actually considered for use?

Sure: I always have the carboy on a workbench, the keg on the floor, and need just 1-2 psi to get things going then back down to under 1 psi 'til the carboy is empty...

That's an open connection there on the gas post connected to the bucket?

3/8" ID on the tubing to the keg?

I had been thinking about whether another cap would be better but you went with the worm drive clamp. The only other option I thought of was a two hole stopper but they are slippery when wet. I thought about maybe a wire cage, something like a champagne cage but it seemed like it would be fussy.

That's your scale system, that's pretty cool BTW, but what does the top cable do with the green light?

I've been struggling with the hose exiting my plate chiller and sitting just five feet away I have wood clamps but for some reason hadn't put the two together so thanks there!
 
- fwiw, I run a vent tube from the gas post to a bucket of water. This obviates any notion of atmospheric gases somehow getting back into the keg.

- yes, 3/8" ID PVC. Fits over both the SS racking cane and the 1/4" mfl beer QD stem: bigger ID = faster transfers without resorting to higher pressure :)

- yup, power adapter. Keeps the scale from simply powering down on me mid-rack. Which wouldn't be that big a problem as I work with gross not net, but still.

btw, the kegs start out "Star San Purged" so before anything gets plugged on they get CO2-purged beforehand.
Like the beer line, the vent line, etc, and I blow quite a decent amount of CO2 through the carboy headspace before starting the transfer...

Cheers!

I used a setup similar to deadalus with the gas fitting pushed into the orange carboy cap. Used it to transfer wine. If I remember right, had to hold the cap down to seal and would only hold 2 or 3 psi. But worked

I do this with beer, wine, mead, and cider; from both glass and SS fermenters. A little CO2 starts the vacuum transfer and then I let gravity do the rest. Sometimes I have to hold the orange carboy cap to keep the seal and the transfer going, but I don't worry too much about the pressure in the carboy as the keg is venting as I add the liquid to it.
