Re: Cab Cleaning (Ronnie out on the line)

If you open the water supply valve all the way and put the injector on, it will run a "full" stream out of the squirt hose when you turn it on. This will also probably put more water in the boiler all at once than you want when the engine is working upgrade, and will negatively affect steam pressure.

When you screw down the water feed valve with the squirt hose valve open, the discharge from the hose will change from a solid stream to a "spray". The "spray" volume (how fine a "spray" it is) can be used to "pre-set" the injector water supply valve when getting ready to start up grade, and save you having to diddle with it when you need to be busy putting in a fire. It will get it "close", and then you can regulate it further, more or less, to make up the water the working of the engine is using later on, between fires.

This "spray" from the squirt hose also makes a mighty fine "broom" for sweeping coal dust and dirt out of the cab and gangway, and wetting down the coal pile in the tank. That is what the fellow in the video was doing.
