thought of you.  

 

 

The paper cover was already damaged as found.  

@Artie been doing electrical so long I bet he has one in his pouch! Cool find!

Nope.kinda amazing how much we don’t figure voltage drop into our calculations. Unless you are talking LONG distances or lower than 120 volts, doesn’t really affect normal wiring much. Kinda like you get two 50 foot, 16 gauge extension cords, and then run the circular saw off them all day. Maybe it heats up more than normal, maybe the cords get warm, but mostly everything keeps on chugging.

16 gauge 

I've got tools that won't even start with that light of cord. 

I've probably warmed up house wiring using my 12 gauge cords.

My Shopsmith used to dim our lights, hows that for power! 

Wow, a slide rule for electricians. Artie probably doesn't need one. He's got it all memorized.

As long as it didn't dim your enthusiasm.....

Harmonized, memorized, whatever it takes.

@Artie,

Kind of like the one for reading resistor color codes.

You know the one that starts with "Bad boys..."

Text says 1946 NEC.  Since code is updated every three years (altho not sure when the interval was back then), slide rule itself dates to the late 40's?  

 

There is a museum devoted to slide rules, and I noticed they have electrical ones.  If you want history,  https://www.sliderulemuseum.com/MiscUSA.htm

Geo. Worthington was a Hardware Store wholesale supplier....based up in Cleveland, OH...something like 16,000 different items in their catalogs...

That little red block plane also came from Cleveland...

Gotta be honest here, only got 1 tattoo. Shamrock on my upper left arm. Hasn’t really changed too much in shape   Color has definitely faded a bit. Got it in Rantoul Illinois 1979, right outside the gates of Chanute AFB.

Never learned the resistor code. Wasn’t needed till the last two years. Now that I work with security systems, gotta put end of line resistors in, for supervisory circuits. I got a box of resistors and just match the others out of the same panel. (This part of the job just ain’t that hard).

I have never even held a slide rule, never mind use one.

I have some interesting applications of use for them, on certain engineers that designed the crap I have to fix.  

  Gunny must have a little electronics background...seems he knows about the "Bad boys..."

Sneer not we at Engineers.  There is a whole industry (including me) employed in fixing their errors .  Credit where credit is due:  they break things faster than we can fix.  It's called "job security".

Might remember back when...

You would wire a resistor and a capacitor together....to make a "filter"

You could take a suspect "tube" to the store, use the Tester they had, and if the tube was bad, buy a replacement...

When some tubes had a "shield" over them...and others had an "anode" in the top of the glass envelope...

 

When, for laughs, you'd "charge up" a capacitor with the leads bent just so....toss the bundle over to someone,,,and tell them to "Catch it!"

Sitting in the car...waiting for the car's radio to warm up...then tune in CKLW-AM, and listen in to Wolfman Jack...or the King Biscuit Flour Hour......

I’m turning 60 in March, I remember taking the tubes out of the tv and bringing them to an electronics store, and testing them to se which one/ones needed to be replaced. Remember the ones that had the wire that attached to the top. Never made a filter, or played with capacitors, but did hear the stories about tossing a charged one to others. Wolf man was just a little before my time, but the King Biscuit Flower hour I remember, or at least references to it.
