Converting a corny into a conical?

[Frankenhop]

I had an idle thought and figured before I go out and do it to ask the BN Army a question: has anyone, as far as you know, ever turned a corny into a fermenter conical? As far as I can tell it wouldn't be all that difficult with a little welding knowhow. Just slice the bottom of the corny off, slap on a cone, and attach a dump valve & frame to keep the puppy upright.

Sure you could get fancy and add a sampler/racking arm and maybe even coil it with a refrigeration-tubing heat exchanger and a neoprene jacket & thermoprobe sensor, but even a basic setup would theoretically give you nice low footprint 5 gallon fermentation chamber with the capability to co2 prefill and pump without worry about air contact. So has anyone ever done this before, or am I just crazy to consider it?

~Edit~
Another thing to consider: The only real thing I'd be worried about is the downward pressure from the narrowed chamber and it's effect on yeast, but at 5 gallons would that even really be a concern?

If you are a welder with mad stainless skills, or you know one that is that is indebted to you (maybe you saved his live once?) - then it's totally possible.

All that work for perhaps a 5 gallon fermenter is almost pointless in my book.

I'm looking into making a fermenter out of a sankey keg right now, but it probably won't be very conical-ly.

hopefully you're at least considering using cornys that are no longer useful as an actual serving vessel

why bother making it a conical, a corny is almost perfect already with a cut down dip tube.

Simple answer? Yeast dumping and the coolness factor, really.

Cancel this one guys, seems the vertical pressure of even a 5 gallon system is enough to stress the yeast and increase ester production. Oh well, sounded fun. Looks like I'll just be going with a Toledo Metal's hopper & a pressure clamp lid setup instead.

Where did you get this info on vertical pressure? I was planning on modifying a corney to use as a primary (as Bub described).
