Emergency Power In Ammo Case.

It all started when I noticed on the shelf of Home Depot a plastic ammo can.  Immediately I thought it would work to hold my 12 volt gel cells that I use for emergency communications.  I am a ham radio operator who volunteers for the local city RACES group.  The very next day I went to Ham Radio Outlet to buy RT Software.  In the store, on the counter were two battery cases with no battery but on the outside of these cases was the interface for Anderson power poles.  I asked the store clerk about mounting Anderson Power Poles into my ammo case.  I was shown a product that made my socks roll up and down.  A company called Powerwerx had some pretty cute devices for mounting into cases.  I purchased three of these, all different, and they are:

  • Anderson Powerpole connectors (2 included in the module).  The module comes with its own mounting plate.  I will not use this single mounting plate but instead put all 3 devices into a single large plate.  The Anderson Powerpoles will provide power for my ham radios.
  • USB connectors  (2 included in the module) to offer emergency power for cell phones.  This module comes with its own mounting plate which I will not use.
  • A volt meter showing the battery voltage and it includes its own mounting plate.
  • I also purchased a three hole plate that makes all 3 of these modules look really nice.

 

The next day I drove over to Batteries Plus, Brea, California,  to see what battery they had that might fit into the ammo case.  The store clerk immediately picked up a Duracel 12 volt, 14 amp hour battery that slid into the case perfectly on 3 sides.  I had some extra room at the end of the ammo case for other items.

I only needed to use 5 of the 8 pairs.

Misc Items: 

  • Red and black heat shrink tubing. The red obviously slips over the positive female disconnects and the black over the negative.  TRICK:  I borrow my daughter’s or my wife’s hair dryer and set it on hot and high. I then put part of my hand on the air intake to limit the air coming into the the hair dryer to raise the temperature.  In this way, the heat shrink rapidly shrinks around the female disconnects.
  • .250″ female disconnects.  The devices come with female disconnects but I am using larger diameter wire and do not use them but buy larger wire size connectors.  I like to use bare metal connectors, solder the wire to them and then heat shrink the ends.

Rough Cost:  I had the wire, connectors, heat shrink, and hardware so these items are not added.  My rough total for items I had to buy was about $180.  I would have to guess that if you do not have the items I already had on hand, your cost will certainly go beyond my cost.

 

Steps To Build:

Place 3 hole panel plate on top of ammo case on the side next to the handle but away from where the handle will fold into the case.  Center this plate.  Take a look at the under side of the top lid and get an idea of the plastic braces that will need to be cut away later.  I found it best to really get away from the handle as much as possible to avoid the internal plastic walls.

panel-marking

Mark the 3 large holes and 4 small plate mounting drill holes.  I made a mistake of drilling the 4 small holes first.  When I drilled the large 3 holes I found that my prior 4 holes did not line up exactly and I had to drill them out again.  I really recommend that you drill the large holes first.  Put two units into the large holes and then drill the 4 small mounting plate holes last.

Open the top lid and look inside and judge where the 3 large holes and 4 small holes will come through.  You will find that you are going to collide with small internal vertical walls.  Think this through to make sure you do not have to cut them out too much.

Drill the 3 large holes for the devices.  I use a Kline Tools #59009 Step Drill bit (made in the U.S.A.) that is wonderful and fast for thin wall drilling.

Drill-bit-for-holes

Trick:  With this type drill I do not come down to finish the exact hole size but stop short.  I pull the drill out and see if my cut is exact or not.  I will see my circle mark I had made with a marking pen and the cut.  As you can see in the image below the drill does not line up.  I then can adjust the drill by pressing in the direction to fine tune my cut to be more exact, as you can see in the right hole seen below.

drill-holes-do-not-line-up

Powerwerx.com who sells these devices sells the exact hole drill, 1 3/16 inch, for $17.99.  https://powerwerx.com/panel-mounts  With this type hole drill, you can more easily center the hole cut.

I then used a round file to do some simple trimming of each hole and tested to see if each module would slide in and out of the hole.  Just remember that the cover plate will make it look quite good.

Drill the 4 corner holes for mounting the plate.  I measured the 4 plate mounting holes 5/32 drill bit fit tight as I tested the plate holes.  I am not that precise in centering my drill holes so I often times go a bit larger in drill bit size if the plate fails to line up properly.

Open the top lid and look at the under side of that lid.  You should see some plastic wall braces.  You need to mark them for how much to cut.  (See Image).  This is where you really need to be careful.  I came too close to the walls in places and used a Dremel rotary tool to make finishing touches.

I used a Dremel Tool to cut away the plastic braces under the top lid.  I used grinding stone 8193 at high speed to melt away the plastic that was in the way for screwing in the large mounting nuts.  I really recommend that you have terrific light shining upon your work as you “cut” through the plastic.  The melted plastic was a pain to clean out.  I put my Dremel tool on slow speed to help remove the pieces that glued themselves back upon the lid and also to polish edges and surfaces.  As you can see in the image below, the inside looks quite a mess.  The outside should look quite good when you are finished.

chassis-connector-rear
Notice that the nut holding this device is under the plastic internal wall. I took care to cut the wall close to the lid only. I slid the nut under this wall and then rotated the nut as the device was in place.

Trick:  The internal inside lid walls are quite deep.  The grinding stone wheel #8193 is much shorter.  I decided to slide the wheel into each wall close to the lid, thus making a short open doorway, thus leaving much of the wall untouched.  When I mounted the devices into the 3 holes, I only needed to slide the mounting nut into place and as the device was pushed into the box lid, I would tighten the nut.  (see image).

The inside of the lid looks way less pristine after I melted the plastic in places but the outside looks very good

Battery in Ammo Case:

There is 2 1/4 inches from the top of the battery to underside of the case lid which is air space.  But, the devices mounted on the lid come down just over 1 inch if you use straight connectors.  Thus, the total top air space between the top lid devices and battery is close to 1 and 1/4 inches.

Left side module offers 2 Anderson Power Pole connectors, 12 volt. The middle module is a volt meter. The right module offers 5 volt USB power for cell phones or other devices.

The battery does not occupy the full length of the ammo case.  There is a 3” length x 4” wide x 5 “ deep cavity at one side of the ammo case next to the battery.  I am currently looking for a plastic box to insert in this space so the battery will not slide.  I could put fuses, fuse puller, small meter, etc. into such a box.

I am now researching attaching an optional solar panel to this battery.

CERT TIP: Coaches Wristband

Last revision: May 1, 2016

Let me start this post by defining some abbreviations that you need to understand before reading my main post.

CERT stands for Community Emergence Response Team.  These are city volunteers that are trained to go out into their neighborhood after a disaster and administer aid.  These individuals may very well be the first individuals that give aid.  City governments offer free classes and typically follow this up with simple protection gear for these volunteers to use.

RACES stands for Radio Amateur Civil Emergency Service It is a group of amateur radio operators that volunteer their time and equipment to offer emergency communications to some U.S. government agency whether that is city, fire or police.  Some cities put one RACES member into a geographical area to serve as long distance communications member because in large cities CERT FRS radios might not make good communications to city government due to distance.  RACES typically have the capability for a city to send messages very long distances.  Their role is typically to maintain constant communications with CERT groups, city, the county and even state agencies.

FRS stands for Family Radio Service.  These radios do not require a special license so CERT members can easily use these radios. The radio manufacturers advertise these radios will communicate up to 30 miles.  Do not believe it.  Two miles is average.  This is a short distance radio system.  Some cities use this type of radio communications for CERT individuals and teams.  These radios are cheap and very easy to use.

Back to my story:
I had taken CERT class years ago and cribbing, extracting people from collapsed buildings, was probably, the only skill I still remembered.  Our city RACES group members were encouraged to sigh up for the CERT class again if we had not taken it for a long time to refresh our memories.  I decided to take the class again.  When we got to the section covering triage, I fully expected that I would forget what I had learned.  I asked a friend of mine who had taken CERT about a year ago and asked him if he could remember the triage procedures.   He could not.  I rather quickly came up with a solution.  I remembered seeing football quarterbacks having a wrist band that showed vital play information on their arm.  I looked for this device and quickly found them for sale.  The one web site I read reviews about this device revealed that the military uses these.  There are a number of these wrist devices.  I decided upon the SteelLocker Sports X200 Adult Play book Wristband.  It cost me $7.99.  It does not use Velcro to adjust to your size arm but a soft elastic sock, about 6 and 1/2 inches long, which holds a 5 and 5/8  by 3 and 1/2 inch plastic sewn in window.  If you have a thick arm, I suggest that you look at Velcro adjusted wristbands.  The top page part of this wrist arm band window lifts up so you can use both sides of the top portion and then view the bottom.  You thus have 3 windows.  You slip in your paper notes into slits along one side.  I measured and cut my notes to 2 and 1/2  tall by 4 and 1/2 inches wide.

A wrist band is shown and the top page has been lifted up so the bottom of the first page shows the second triage procedures and then under this top page and resting next to the arm is the final of three pages showing the final triage procedures.
Coaches armband top page has been lifted up to reveal two more pages of triage procedures.

Following are my list of note pages:

These pages were updated May 1, 2016 after I had Captain Alan Wilkes from OCFA, who also teaches CERT, looked over two of my pages.  He reviewed only Triage 1 and 2 pages only.  He did not like my long winded presentation and said “stay out of the weeds”.  I took his suggestion and added a single page called RPM (see below).  I still think there is a need for TRIAGE page 1 and 2 because most of us hardly ever have to use these skills.  People who have to TRIAGE more frequently probably only need the RPM page.

Top page: Emergency radio frequencies: RACES, Red Cross, Hospital Group, FRS frequencies.  Each is fully labeled as to ID, repeater shift and PL tone.

Optional radio template:

RADIO Template


Page 1:  Triage procedures in .pdf form.  I created these documents using Pages.  Font size is 7pt.  I confined the text into a 2 and 1/2 inch high by 4 and 1/2 inch wide space so it would slide into my X200 Coaches Writstband (adult size):

TRIAGE 1


Page 2: is a continuation of the triage procedures.

TRIAGE 2


Alternate top page:

Here is a single page that show, in a very brief form, how to perform the whole TRIAGE process.  This single page is intended to replace page 1 and 2.  Another idea is to put the RPM page as the top arm band page.  You could then open the arm band to see TRIAGE PAGE 1 and TRIAGE PAGE 2 for more detail.

RPM


I am still going over these documents to ensure they are accurate for content and clear in how to use the directions.  If anyone sees a mistake or improve the wording, let me know.


The reason I went to all this trouble is that triage is what scares me the most.  The triage process we are making life and death decisions and I do not want to screw that up.  I want those procedure to be ready after I forgot them.  I put this arm band into my CERT backpack.

Another, being prepared, solution was suggested by Mrs. Anna Lee Cave, Emergency Preparedness Coordinator for the City of Brea, California.   She sent me this link: http://quickseries.com/index.php?prodcode=01-0595-000-01  and recommended the Field Operations Guide.

I hope you find this helpful.
