If my gauge is right 27.5. If you get 30 I would say you got a really strong pump. The maple takes on the juice till it wont float.
I will have a bit left over for youins that want to try it on sumpin else. Better wear prtection though
I'm confused about this (nothin new for me
). Wouldn't the absolute Max vac pressure be the same as the barometric pressure?
Maybe the process could be further enhanced by placing the wood and the juice in a tough but flexible plastic bag and then weight it down and submerge it in deep water?
According to calculations, there is .433 PSI per foot of submersion. One could obtain 30 PSI at a depth of 69.284065'.
At 140 feet the pressure would exceed 60 PSI. Probably not that many places where we could practically and legally submerge the project.
I foresee a new form of bowyer misbehavior, "pressure poaching".
The cabin fever is level reaching dizzying heights. Come on spring.
