Fasten your seatbelts. Let's build the Mashimizer !

Ok, where to start...
So much information available, so many clever people all over the place.
I've been reading, building, playing, dreaming...
I'm hoping to combine the best ideas I've come across into a working design. That's where you all come into play, chip in!
This thread is going to be about building a mash boiler/fermenter/stripper. Add distiller maybe once I build a flute (in the near future).
Design criteria:
Be able to mash, ferment and distill on the grain.
I've been frustrated at having to throw out 1/3 of my fermented washes locked up in trub!!!
Standard grain quantity: 25kg/55lbs sack of grain.
Volume of water 2lbs grain per gallon of water: 27 gallons.
Hey what do you know, a 30 gallon design falls right within the forum rules.
Double wall, bain-marie boiler with steam injection is what this is all about.
Here's where I'm at now.
I purchased some 16 gauge 304 stainless sheet, had it rolled and cut to spec.
Inner tube dimensions: 22 inches high with an OD of 21 inches.
Outer tube dimensions: 26 inches high with an OD of 22.5 inches.
This should result in a boiler volume (mash container) of roughly 30 gallons.
Water jacket thickness: 3/4"
Boiler section 4" deep plus water jacket should result in a boiler volume of around 12 gallons for the bain-marie.
Everybody likes pictures, so here we go...
