100 YEAR OLD PC
    #5379793 - 03/08/06 11:45 PM (17 years, 10 months ago)


For the sake of "scale", the pressure gauge is HUGE.
Holds a 1 gallon jar, or 6 quart jars.
(4 standing & 2 sideways on top the standing ones)

They don't make PRESTO pressure cookers, like they used to.  :rolleyes:

I was shopping for 20 ft steel "I" beams at a surplus steel yard, which also recycles various scrap metals. After finding & purchasing what I needed. I browsed around their yard, a few minutes, while waiting for the "I" beams to get loaded on my truck.

In the huge 15 ft tall aluminum scrap pile, I saw a hvy duty OLD PC that sort of looked like an AA :confused:. So, I scampered up the pile & grabbed it. After eyeballing it to insure it was intact, I carried it to the yard office & asked what they wanted for it.

With a puzzled look, they answered, $5, so I bought it. :grin:

The company National Presto, then called Northwestern Steel and Iron Works was founded in 1905 in Eau Claire, Wisconsin. At it founding, it primarily manufactured industrial-size pressure canners, known as "canner retorts," for commercial canneries.

I took this near 100 year old metal to metal seal :grin: PC home & fired it up for a low pressure test run. SOB worked like the day it was brand new :grin:.

I am going to polish the puppy up shiny bright & replace the gauge & pressure relief valves with brand new ones. Threads are compatible with ALL American PC & Sterilizer parts, which I happen to have (already) :grin:.

Not that I need ANOTHER PC.  :crazy2:
But, this old one is REALLY an antique. :wink:

Amazing what you can find, if you keep your eyes open.

pretty cool find agar, but i have to ask... what in the world do you need 20 ft steel I beams for? I mean, are you adding an addition to your house, or from reading your posts, more likely creating your own backyard radio telescope?

First test run, I only took it to 10 psi.

Second test run
(in the shop, not the kitchen)
I took it to 25 psi.

It's SOLID.

awesome, although its sort of unrelated to cultivation, i hope you give a log of the building process of the barn as well :smile:  Creation is creation right? Realy though, it looks really cool, ive been in the construction trade building houses for the last 4 years, had enough and looking for a career change, but i still find it all interesting.  All your projects are quite thorough and very fascinating to read.

I will keep the original parts, just for that purpose & re-install them, when that time comes.

Just tinkering, for fun.

It's cool and all, being such an old peice, but I personally don't exactly find pressure cookers to be aesthetically pleasing or decorative.

Hell, it'd be more impressive if you tell people that it's 100 years old and still actually gets regular use, rather than it just sitting on a shelf.

im not sure if this applys to the pc you have or not, but i remember hearing that the old pc's were dangerous and had a tendency to explode. Im not sure if this applys to the one you have or not but i would check into it for safty. of course it hasn't blown up yet so maybe im just stupid.

I do believe that's why he said he tested its performance under higher pressures in his shop rather than the kitchen.

As always Agar, wonderful, that thing is a beauty and will I am sure bring you years of joy, a trouper like that is a keeper.

And anyone who says pressure cookers aren't sexy is wrong. I find anything that can get it going hard and keep its steam pretty damn sexy. ^_~

Old time PC's can be dangerous, if the seal gaskets, casting or safety release valves are bad.

This one has seen a considerable use.
That tells me the casting is sound.
I tested the safety release valves under LOW pressure & they function.

However, I am replacing the safety relief valve & pressure gauge, with modern ones.

Just for safeties sake. :thumbup:

I have considerable experience with high pressure vessels, autoclaves & PC's. I would not advise any inexperianced novice to tinker, or alter a pressure vessel of any sort.
Unless, done under stringent safety protocols.
