Stingers


Ubiquitous (is a fun word); it describes the stinger.  It is the set electrician’s most used piece of equipment.

I don’t know where the name came from.  It sounds cool.  It implys to me that it is something that can sting you; you can get a shock from it.

I assume it is another one of those old Hollywood names for equipment, like the C-47 (a clothespin).  I assume, too, that the source and meaning of the name is forgotten.

You hear different versions of where C-47 came from; it was a studio’s inventory name, it was a studio’s bin number for clothespins, etc., but none are convincing.  It’s probably the same with stinger.

I am surprised by how often I see bad stingers from rental companies: the cable is not a SJO-type; the jacket is torn; the plugs are loose or damaged; missing ground prong; reversed neutral and hot; and every set electricians’ peeve; tie-lines missing, damaged, or too short.  It creates needless work for set electricians and makes the rental house look bad.

Here is a good looking stinger from yesterday’s April 1st post:

Here's a good stinger:  SJO jacket in excellent condition, heavy-duty plugs, nice long tie-line, and even a heat-shrink label.


If you had any question about yesterday’s post, plugging-in the ends will, of course, not damage the cable.  It can be a good thing, since this protects the pins on the plugs.

I don’t think any set electrician normally plugs-in the ends.  I do it sometimes when the plugs end up opposite of the tie lines.  It’s just a way to keep the loose ends together.

PS:  With bates cables, I will often loosely plug the ends together.  It is a way to protect the pins from damage.

The pins on bates cable are easily bent: which causes a bad connection; which leads to "what is that smell?"; which leads to finding a melting bates plug; which leads me to telling the DP "I need to shut a light down and re-patch it", which leads the DP to wonder, "does this gaffer know what he is doing?" 



PPS:  When I was a young man in this business (not long after dinosaurs were roaming the earth) most stingers were made with SO-type cable.  SO-type cable is made for heavy service.  You often see it hanging from ceiling boxes to power equipment in factories.  Unfortunately it is like twice the diameter of SJO-type cable.  You can imagine how bulky these things were.  SJO cable is much better for what we do.
