DIY MRE

The MRE or Meal Ready to Eat Has been the go to combat ration since 1975 for the US military.  Each MRE provides an average of 1250 calories(13% protien, 36% fat and 51% carbohydrates) and 1/3 of the military recommended daily allowance of vitamins and minerals. A full days worth of meals would require three MREs. (I got this information here MRE INFO)  Bulk alone in my opinion makes them a poor choice for a 72 hour bug out bag. Nine MREs will take up a huge portion of your bag.  Another consideration is cost. A quick google search shows a case going for $83 plus shipping on Amazon.  If you were to purchase this case of MREs each has a price tag of $6.92,  three of them total $20.75 and a 72 hour supply would run you $62.75.

Putting together your own MRE will save you both money and valuable bag space. Making your own MRE is as simple as gathering what you want for a days worth of food and stuffing it in a bag. I used a vacuum sealer for mine.  Every item in the one we will be working with here is prepackaged for both expediency and simplicity. The drink mixes, sniffle pack(pills), tea bag, condiment packages and bullion cubes I scrounged around the pantry for so they will not show up in the final cost we will talk about in a bit. I purchased all of the rest of the food at discount grocery stores for very reasonable prices.


Here is what I put in one. It contains 3 meals plus snacks. 
             
The finished package measures 9"x7" and is 2 1/2" thick


Three day supply stacked on end all  three of these MREs are identical with the exception of small differences in the package shape and dimensions

Now that we have our MRE ready to go lets talk about cost and nutrition.

 MRE Nutrition I will be referring to this spread sheet I made up.


COST

Like I said before to keep the cost of these mres down I did my shopping at discount stores. This dictated a lot of the contents as I was looking to make these as cheap as possible. You can look on the spread sheet I linked for a cost breakdown per item. I came up with a cost of $6.43 per MRE. A three day supply totals at $19.29! That is less than the cost of a single days worth of the commercial MREs.

Calorie Content and Nutrition


Again referring to the spread sheet we can see the the breakdown of individual food items.


Calories: % Formula Key
TC Total calories
Total: 3130 F Grams of fat
Calories From Fat: 39.97% Cb Grams of carbs
Calories From Carbs: 44.60% P Grams of Protien
Calories From Protein: 4.54% S Grams of sugar
Calories From Sugars: 3.64%


To figure out the percentages you need to know that fat equals nine calories per gram.
multiply the total grams of fat by nine then divide that number by the total calories of the MRE multiply that number by 100 and you get the percentage.


F x 9 / TC x 100 = % calories from fat 139 x9 /3130 x100 = 39.97


Protein,Carbohydrates and sugars all equal 4 calories per gram so you can simply plug in those numbers intothe same formula to derive their percentage.







  • If you add up the above percentages they don't come out to 100% I'm not sure where the missing 8.25% is but I believe this is close enough
  • One very alarming statistic came to light as I was gathering the data from the nutritional information on the item packaging. This MRE contains an astronomical 6640 MG of sodium. This to say the least is not good.
  • The contents of these mres were bought at discount stores most of the items are either close to or already beyond the pull date so in theory the shelf life is much shorter 
  • Protein seems a bit low to me but I have not yet looked at the RDA so I am not positive it actually is 

When its all said and done I have enjoyed making these and I feel some sense of accomplishment in having at least a small part of my BOB complete. These MREs are not the most healthy or nutritious meals a person could put together but they are certainly better than nothing. In the future I will be working on improving them. Home made meals dried in a food dryer comes to mind both to reduce the sodium content and overall weight of the package.

This has been a great project and along the way I managed to learn a thing or two I hope you have as well thanks for reading.

Knife Build #1


Let me start out by saying there are far better ways  to do things than what I am going show  here. Knife making like most other things can be as simple or as complicated as you want to make it. This time its going to be simple. I want to demonstrate the fact that you can build a good working tool for little or no money.
A  knife is without question the most important tool you will  need  in any survival situation. I don't know about you but I don't want to have my life depend on some garbage five dollar knife made in China, especially when you can make a great knife on the cheap out of an old file with household tools.

Files are made from high carbon steel and make excellent blade material. I picked one up at a yard sale for a quarter so that is what we will be working with. This file is a  Simonds.  I don't know much about the company but I  looked them up and they seem pretty reputable to me. I do know that Nicholson files  are made out of 1095 high carbon steel and I can't see any reason this one  would be any different.       
 Here the teeth are ground most of the way off.  This particular file was heavily rusted so I wanted to see how deep the pits were before I went further. You can skip this part until after you anneal the steel if you want.

Closer view

 At this point  the file is very hard and brittle so we will need to soften it before we start work on  shaping the blade. This process is called annealing. In a perfect world I would use a forge for this but I don't have it set up right now so we will be using a wood fire for the annealing process. I didn't realize  until it was too late but my camera battery was dead so no action pics of the actual fire.  I got the fire going until I had a nice bed of coals and buried the file down in them . I used an air compressor and blasted the coals with air to simulate a forge blower. I wouldn't recommend anyone else  do this since its probably very dangerous. It was making my welding gloves smoke from over 3 feet away from the coal bed and I got a hot one down the cuff of my glove so now I have another pay attention stupid mark on my arm. Give it a try if you want but don't say I didn't warn you if you get burnt. It worked like a champ.  I could see the file down in the coals glowing nicely.

The idea is to heat steel the and let it cool slowly. Let  fire burn out and cool naturally, 
There is a ton of information out there be had about the rocket science of metallurgy and what heat does to steel and how to do it properly but for our purposes this will work just fine. so the fire is going and blade is buried in the coals so nothing to do with it but wait.

The fire pit post burn


here is the file I  unburried from the cooled ashes
As you can see the there is a slight warp  no problem it straightened right out with a few love taps 


Initial shaping started here with a rough sketch


close to final shape I didn't much like the knob on the end so i removed it.

Final shape with the pin holes drilled for the scales the  and a close to mirror finish.  The handle scales are below I will talk  more about those in a bit
The blade shape was not how I intended it to turn out.  It sort of just turned into what it is after correcting a few mistakes in the grind. It should be a great small game or fine carving tool all the same.
I wont go into a lot of detail on the actual shaping of the blade its all pretty much common sense. I used  a combination of the belt sander, 4 1/2 inch  grinder and files to shape it. I polished the blade with sand paper starting with 220 grit and dropping down in grit coarseness to 1500 until I got a nice  polish. The only thing left to do as far as the blade itself is the heat treat, temper and final polish. I am waiting on the heat treat until I have a few more blades I'm working on ready.


In the mean time we can talk about handle material. There are many good materials for handles.  Natural material like  bone, antler and wood  to man made material   like canvas  micarta or laminated woods such as diamond wood. We are going to use wood I am using madrone but any hardwood you can get will work.
This is not the tree I used. Just an image I pulled off the net to show you what it looks like
I found a small tree(about 4"in diameter)  up near the house. Not that I really care but for any tree huggers out there this particular tree was already well on its way to being dead. I chose it because something was killing it and that can often lead to some cool grain pattern or unusual color.

I used a band saw and slabbed out a few pieces to see what I had to work with.

here they are with the file for some scale 

Pretty eh?
These slabs are approximate 1 1/4"wide  5/8" thick and 11" long. This is green wood so it will have to be dried to before using. You can skip this step if your wood is already seasoned and dry.

I set the oven to 215 F  and baked the slabs for about 4 hours. I let them sit the sun  all day today and will give them another bake tonight. I did a bit of reading on drying wood in a household oven there are folks that say don't some that say its fine some even say to use the microwave almost all said to use a moister meter to determine if the wood is dried completely. As it happens I left my Acme Plasma Drive 40 watt range  MeasureTron 2000 Moisture Meter in my other pants so a few cycles in the  old oven will have to do.

 rough cut scales they will need to be shaped after  they are pinned and epoxied to the blade
Like I said earlier I am waiting to finish a few more blades before I set up the forge and do the heat treat so I will post what I have so far and come back  with final assembly once that is complete.
