Has anyone tried putting an airlock on the gas post and using the corny as a fermentor?

Thoughts:-
1. wrong shape ? small surface area of the wort head compared with the depth of the wort in a cornie will mean very thick yeast head (and I know about such things
). The head will escape through your airlock in large volumes I would have thought.
2. Volume too small. If my target vessel for storage is a cornie then my fermenter always have a few more litres than the cornie as there will be losses during the skimming/racking process. Using a cornie as a fermenter will mean that the destination cornie won't be full (perhaps not an issue? but seems wasteful).

Frothy
I'm doing an american recipe thats 5gal (US) and I've been looking at my plastic 30L fermentors and thinking they're a bit big. I know what you mean about the problems with yeast head in the initial fermentation - in my last brew in my big fat fermentor there was at least 2" of froth at one stage. Also the cornys are not as easy to clean as the plastic fermentors - particuarly at the top.
sooo fermentor for primary and I think experiment with the corny for secondary with tribs
- excellent
who-ever designed these things I'd like to give them a medal

I'll be using a blowoff tube instead of an airlock so the airlock doesnt get filled with yeast. I may switch to an airlock after the initial explosion.
Losses will be minimised in a corni, infact by drawing off the slurry it wont be necessary to use a secondary, besides by starting at a higher SG the corni can be topped up if required.
I'm pretty much sold on the idea and it saves me the bother of setting up a transfer pump.

You could make a Burton Union to collect the yeast and the beer drips back into the corny. There's an article on how to make one in this months Brew Your Own magazine.
