I like your style 3500lt! I totally want to build one too.
I just had a thought. How about plumbling a 22 quart mirro or presto into the barrel and using it as a steam generator since it already has the 15 psi pressure bob?

Nice thread. This is what i'm in the process of building atm. I have ordered the pressure gauge and weighted adjustable regulator for a presto canner from amazon. Cost around $50au delivered where the canner costs $250 here in Australia for a presto one and another $100 for an all american...
I already have a 50l keg boiler for my stills, in one of it's guises it's used as a steam generator for cooking grain in a much larger pot..

It has a 4" hole in the top and 4 studs to hold the flange down. I intend to replace the pressure gauge that goes in the top of that rig (not shown) with the more sensitive presto one, and add the regulator to a cap and screw it into the 1" ball valve that's on top as a refill port.
Should have some more detailed photo's over the next couplea weeks when my parts arrive.

off topic........... i would like to see the inside of the black wash pot jacket.
on topic .. will you divert the steem generator to the new container or remove the inerds of the blak thing and use it....also will it hold pressure?

Sorry for the off topic, but the insulated black pot won't hold much in the way of pressure, i just cook grain, ferment and then strip off the bulk alchohol in it. Inside is just a simple drop of 1" copper with a tee and two short arms with holes drilled all the way round at 4 and 8 oclock for steam injection.
The keg will be the pressure cooker, i figure 50l will hold plenty for what i want. Plus i have another with the top cut out for pastuerising straw.
Although i'm thinking of using the large black pot for steam pastuerising substrates. Do y'all think that would be better? It's 160 litres total volume...

im going to purchase a tig welder this spring for welding on a stainless drum like this one.
http://cgi.ebay.com/BARREL-DRUM-STAINLESS-STEEL-55-gal-47lb-food-grade_W0QQitemZ180463692549QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item2a04796b05
-weld a thicker bottom on it.
-weld legs to raise it off the ground and fit a propane burner underneath.
-cut the top off and weld pegs inside to layer bbq racks about 8inches apart.
-then the hard part fabricating a good sealing lid with gauges and pressure releife valves.
I just got my 240v hooked up in my garage last night so im ready to run a bead.
If all goes well and i can build 1 or 2 of these that are functional, then i might convert my garage into a fruiting chamber(dont flame the idea), with all the goodies!
I wanna grow bulk shiitake, reshi, and oyster mushrooms and sell them.

Since we are all sharing our two cents on ideas. would anyone have any ideas on how to build a sealed door for a air compressor tank. that seems like it would be a good pressure cooker. i have lots of old tanks i would love to cut and figure out a way to weld a door on it. then i could just pressureize with steam. would it work>>??

There's two good systems for this. if you were to lay the tank on it's side, you could weld a couple 'hatch' type access's in.
I don't know the policy here on external links, so if you google 'copamate' you'll find round boltable flanges in sizes from small to very large. i use 4" ones and they are heaps big enough to get your hands in 9and i'm guessing jars). The other system to google is 'triclover, or sanitary fittings' i believe st pats is a good place to get em in the states.
These are weld in ferrulles that seal with a clip. There's fittings for anything you could imagine in any size.

Well yippee, i got my canner parts from the states today
Spent some time in the shed a drillin and a brazing and came up with this...



Pictures show succesively, the 50 litre (15 us gallon) keg with a 4" to 2" adaptor, then a triclover blank plate with a genuine vent pipe brazed in. The pressure release sits on top of this, same as all the presto cookers.
The 1" ball valve that is usually used as a refill port when the keg is a still, has a brass cap with an adaptor brazed in to accept the genuine pressure gauge.
I filled with about 8 litres (a couple gallons ) of water and fired the three ring lpg burner up. Only took a about 15 mins to come up to pressure and i turned the burner down to ony the centre ring waaayyy down to about six candles worth of gas to maintain it.
Dunno if it will be this energy efficient once full of bags or jars, but i hope so

Great job. Only concern I would have is no safety valve should the gauge not work for some reason (plugged or you forget to turn the ball valve open) and the regulator not keep up with releasing steam. Should have something like the rubber safety valve that most PC's have.

If you look at the third picture, you'll see a piece of 3/4 pipe brazed to the bottom of the gauge cap.
In order to thread the cap with the gauge on, i HAVE to open the ball valve or it won't go in...It's there for exactly that reason
I have a very simple, very reliable pressure release valve and a gauge to see if that is not working. If i light the gas and the gauge doesn't work when it should i reckon i'll notice.
In order for the pressure relief valve to get blocked while in operation, there would have to be something that rose through the 4" hole into the 4-2" reducer and then blocked the safety vent which has a cross cut in the bottom to stop anything blocking it. I'd have to not notice it working (rocking back and forward and steaming) and not notice the gauge against the stop. Not notice the keg creaking and crackling as the pressure built up ect...
Same thing could happen if i had six safety vents....
