Operation Old Pressure Cooker.

[Worth1]

That is so strange the instructions for the All American say that it needs to jiggle every so often not all the time.
Like so many times a minute or so.
It would be a simple thing to make weights for different altitudes.
You could modify the All American weight for any pounds of pressure you wanted or just make one.
I am not changing the weight I am adjusting the surface area the steam/pressure pushes on.
The bigger the surface area the less pressure it takes to lift the weight.

In other words if the surface area was one square inch it would take 10 psi to lift a 10 pound weight no matter how small the vent tube was.

Dont ask me why I like this sort of thing I just do it is sort of nerdy.

I dont have one to prove it but I can guarantee you I can make the All American vent tube fit the Presto.
Or I would just make a hybrid Presto/All American vent tube.
That way a person could use the All American weight gauge on the presto which I think is one heck of a lot better.

If it weren't for the liability I would start pumping this stuff out by individual orders.
