Cold Iron

Rudyard Kipling

Gold is for the mistress — silver for the maid —
Copper for the craftsman cunning at his trade.
"Good!" said the Baron, sitting in his hall,
"But Iron — Cold Iron — is master of them all."

So he made rebellion 'gainst the King his liege,
Camped before his citadel and summoned it to siege.
"Nay!" said the cannoneer on the castle wall,
"But Iron — Cold Iron — shall be master of you all!"

Woe for the Baron and his knights so strong,
When the cruel cannon-balls laid 'em all along;
He was taken prisoner, he was cast in thrall,
And Iron — Cold Iron — was master of it all!

Yet his King spake kindly (ah, how kind a Lord!)
"What if I release thee now and give thee back thy sword?"
"Nay!" said the Baron, "mock not at my fall,
For Iron — Cold Iron — is master of men all."

Tears are for the craven, prayers are for the clown —
Halters for the silly neck that cannot keep a crown.
"As my loss is grievous, so my hope is small,
For Iron — Cold Iron — must be master of men all!"

Yet his King made answer (few such Kings there be!)
"Here is Bread and here is Wine — sit and sup with me.
Eat and drink in Mary's Name, the whiles I do recall
How Iron — Cold Iron — can be master of men all!"

He took the Wine and blessed it. He blessed and brake the Bread,
With His own Hands He served Them, and presently He said:
"See! These Hands they pierced with nails, outside My city wall,
Show Iron — Cold Iron — to be master of men all."

"Wounds are for the desperate, blows are for the strong.
Balm and oil for weary hearts all cut and bruised with wrong.
I forgive thy treason — I redeem thy fall —
For Iron — Cold Iron — must be master of men all!"

Crowns are for the valiant — sceptres for the bold!
Thrones and powers for mighty men who dare to take and hold.
"Nay!" said the Baron, kneeling in his hall,
"But Iron — Cold Iron — is master of men all!
Iron out of Calvary is master of men all!"

Do you know that when water freezes, the ice expands? This can cause metal to crack and that's bad if that metal is your water pump! Old pitcher pumps have a feature where when you are done pumping water, if you pull up all the way on the handle they will open all the check valves and allow the water to drain back into the well. Now it won't crack when it gets below freezing!

Modern hand pumps like Simple Pump or Bison tell us to drill a small 1/8" 3mm hole in the water riser pipe that will allow water to slowly drain back into the well a few feet deep. This works because on these pumps, the working cylinder is all the way at the bottom of the well pushing water up from the bottom. Yes a tiny amount of water leaks out when you pump but it is worth it because it prevents freezing.

If your water level is lower than 15-20ft, you have to use a deep well pump. These pumps put the check valves down at the bottom of the well and water is pushed upward. There is usually a rod that runs down inside the water pipe that is used to push and pull that pump cylinder at the bottom of the well. Note that you can push water any distance but you can only suck water 15 ft vertical.

Also, look for the weep hole in this diagram above. Remember yesterday we talked about freezing? Now you know why there is a weep hole!

There are two different types of hand pumps... deep and shallow. Shallow well pumps suck water from the well. They can only suck water that is up to 15ft deep or so. If the water is deeper than that, you can't suck hard enough to lift it. So all the working parts are in the top of the well. Most of us are familiar with an old "pitcher pump".

I've noticed a bug in telegram's scheduling.... It often delivers teh first message late. For example, the 7:03 am message was scheduled for 7:00.... instead the 2nd message got published first, then 3 minutes late, the first messsage. Sorry for the confusion this may cause.

Here is a jet pump foot valve.
Submersible pumps go all the way to the bottom of the well. They have a set of wires that go all the way to the bottom to supply them with power. Look carefully and you realize that the motor is on the very bottom so it can be cooled by water flowing past it. These pumps should not run dry because they will overheat, so you should put a float switch in the well a few feet above the pump. Some pumps like Grundfoss have this switch built in.

In most places this is the most common type of pump. They can be two wire or three wire. The three wire models require a small electronics box up top with a capacitor in it. The reason for this is so you can service the capacitor without pulling the pump.

*two wire means two wires and a grounding wire. Three wire means three wires and a grounding wire.

For the past two days we have talked about hand pumps. Today we'll talk about electric pumps. Electric pumps are called "shallow well", "jet pumps" and "submersible" pumps.

If the water table is not lower than 15ft, you can use a shallow well pump to suck water out of the well.

A jet pump cheats this a little by pumping water down the well case in a 2nd pipe, doing a u-turn at the bottom and using the momentum of water to suck additional water out of the well. This is not very efficient!
