Does anyone know what this is?

[jb books]

Stamped AC, measures about 9 inches long and about 7 high.
There is a cutter that swivels, I can't figure what it is.
Picked it up at a garage sale today for $1, had to have it lol

for cutting the armature on a generator, when rebuild generator, you spin the armature in a lathe type device and that hooks to it to cut the copper end

It appears to be a tool for adjusting the gap on aircraft spark plugs. The thumbscrew has directions to "close gap" and the pivoting tip would contact the electrode to be moved. It is missing the threaded adapter to screw the spark plug into and which drops into the round hole beneath the pivoting tip of the tool.

You had to have it huh? So, now what are you going to do with it? Sell it at one of your own tag sales for $1 in a few years after you dig it out from under the work bench....

The "AC" and "close gap" stamping's definitely point towards some type of spark plug tool. That's a pretty big tool to be used just for gapping spark plugs though.

Interesting, Though the AC also made me think toward engine electrical-no clue.
Quick search found one one ebay

Thanks guys, I appreciate the help.

Years ago there was a 4 engine plane with something 24-32 plugs per engine and mechanics changed all the plugs on 3 of the engines and couldn't get the forth done before the plane was needed for a flight. On take off all three engines with new plugs cutoff and the plane was so low it flew around a garbage dump and disappeared behind it before it landed on the one engine with old plugs in it. I remember seeing a spark plug tester in the shop at Delta when they had an open house in the mid 50's in Atlanta, Not everything they flew then was jet like it is now. It tested plugs under compression pressure not just spark in free air.

The failing spark plugs story is in Ernest K Gann‘s " Fate is the hunter" . Great book, **** movie.

Buy the other one and corner the market! Then you can name your price!

It looks like the tool we use to adjust spark plug on aircraft spark plugs

American Pickers would have paid $100 for it. You stole it.
