I love engineering semantics with a healthy dose of parsing!:D

I've been around hydraulics my whole life. As a kid, and through the school years, I worked for dad, at his machine shop.
He also built and sold Hydraulic and pneumatic cylinders and valves.
Alot of our equipment has hydraulics on it, and some of it is self made. The one thing I've learned, (the hard way) over the
years, is to take the time, and spend the money, and put "T" fittings in the system . Plug them, and if you ever need to diagnose
a problem, you can easily plumb in a pressure gauge.

The example, that comes to mind, was about 10 years ago, I thought the pump on the wood splitter, wasn't producing pressure, so
I drove 2hrs each way for a new one. Next day I went for a valve. On the third day, I picked up a new cylinder, and some "T"
fittings and a gauge.

Thanks Will Its amazing how much time and $$$ can be saved by a simple gauge put in the correct place.

I want to see peanut butter pumped at 40,000 PSI. I will bring a large loaf of bread

I think the peanut butter was around 20 psi- at 40K you need steel plate and ear plugs :D

I'm curious Will, after all that time and $$ what was the Fault?

It was the piston seals in the cylinder, but we were in major production mode, so no time to rebuild.
The old one is still in the shop, waiting to be rebuilt. The extra pump, and valve I sold.

It's so nice to have someone else who gets upset with that incorrect statement about hydraulics. You ain't the only one to get tired of hearing it!

Misery does love company!
