This came out of Steve's garage but since it was in a box of other scrap metal and "things" we don't really know where this came from. Sooooooooooooo what is this? If it matters, there is a lock washer on the threaded end under the square nut.

I figured someone on duckboats might know what it was.....

Don't ya hate that? I've got stuff like that around too - can't bring myself to throw it away until I know where it came from.

Looks like a standard Do-Hicky to me. No real idea.
 
Alternate question might be, found this thing now what can I make with it! I,m sure the crew on here could come up with a project to incorpperate it into!

It looks like the main winding of the normal lotus-o-delta type placed in pandermic semi-boloid slots of the stator, every seventh conductor being connected by a non-reversible tremie pipe to the differential girdle spring on the "up" end of the grammeters.

I've always been waiting for someone to put up a post like this where I would immediately know the answer....

....and I'm still waiting.
 
Weeeeelllllll at least I learned a lot of new words in this thread. Hahahah.
 
And isn't that what this forum is all about? I actually still want to know what the damn thing is. It looks like an ice spike for a tire......but can't really see how that would attach....or work!


Dave
 
It's similar to late model automotive headlight and rear view mirror adjustment screws. Not sure if that's it but it looks like an adjustable spacer of some kind.
 
I've seen similar air terminals used in a buildings lightning protection system, but the "spike" side was about 6" longer.
The clamp (between the two square bolts) attached to the grounding cable.
 
I can't think of a smart answer, so I'll offer my real opinion. I am thinking, it is a terminal of some sort, installed by a powder charged tool like a Hilt Gun. The stud gets loaded into the tool, then a blank powder cartridge is loaded, and the stud is actually "shot", like a gun, into the metal frame of a building. After insertion, the nuts and ring are attached.

About thirty years ago, I worked for a big electrical contractor. The electricians used something very similar to these occasionally when working in a steel building.

Jon,

I agree, I think you are right. I used to sell these items and rent the gun used to drive them. (My father and I operated an independent rental store)

These could be driven into concrete as well as steel. There are various "power levels" of the blanks used to drive these and various lengths of "nails" depending on the desired depth of penetration.

I think that is exactly what we see in the photo Dani posted. It's still a mystery what the clip was intended to hold, but I'm sure the threaded portion is exactly what you say it is.
