Letter Re: Question on Two Cycle Oil Mixing Ratios

Dear Mr. Rawles, Perhaps you could help me understand the mixing ratios for two stroke oil. I remember buying the old Homelite oil, you could either buy it in a can to mix with one gallon of gas or a can to mix with two gallons of gas. Most of the new two stroke oils I have seen recently state that they are 50:1. Is this mixture acceptable for my old Homelite Super XL chainsaw and other two stroke equipment? The rep at the Stihl store by us said that the new oils are so much better formulated than the …


Letter Re: Useful LifeHacker Articles

Mr. Rawles: There are so many great and not-so-great ideas on the LifeHacker site including this one I found showing you how to use C cell batteries in place of a D cell compartment in an emergency situation: There are some other interesting things on this site like creating make-shift air conditioning systems using cold well water (others have made emergency air conditioners using beverage coolers, fans and copper coils): DIY Heat Exchanger and Make Your Own Air Conditioner. There is this one showing you how someone made hand washing more efficient while filling the tank of his toilet. [JWR …


Letter Re: Comments from a Like-Minded Virginia Prepper

Sir: I found your blog about a month ago. I received a copy of your novel “Patriots” from Fred’s M14 Stocks and have probably read the thing about 20 times. It sits by the bed. I sometimes just pick it up, open and begin reading. Good stuff. I am a former police officer (10 years) with sniper training, construction company owner( I have built everything except a church) CPA with many years public accounting and have military experience (like you in Military Intelligence. I was what is now known as a 98C [- Signals Intelligence Analyst]). I shoot a lot …


Reducing Your Sound “Footprint” by Countrytek

I’ve been lurking about SurvivalBlog for about six months now, and have found a lot of useful information hereabouts. There are lots of good tips about securing your retreat and making it less visible. One thing I have noticed though is that there appears to be a blind spot. Why go to all the trouble to screen your retreat location from view and practice nighttime light discipline if you are going to announce your presence far and wide audibly? One thing I’ve noticed lately is there is a lot of discussion on stocking up on two-cycle and bar oil for …


Letter Re: Masonry Stoves / Brick Ovens

Jim I have been reading the SurvivalBlog for some time now and thought I would share some information about a retreat technology that I have not seen mentioned. I am referring to a brick oven for baking bread, pizza and a large variety of other foods. Brick ovens have been around for thousands of years, they were very common in Roman times. They are having a revival in the artisan baking community and can also be found in many authentic pizza restaurants. They do take a little work to construct, however it is very simple to operate (decidedly low tech) …


Letter Re: Firefighting Equipment for Rural Homes and Retreats, and Comments of Geothermal Heating

Hi Jim, I thought it prudent to add a bit to Mr. Savage’s fire fighting equipment article. It touches two topics worth mentioning. In the article, Mr. Savage recommends a fire truck, bladder, tank, etc… for firefighting. I have no problem with this unless it is winter. Trying to pump this much water on as “as need” basis in the event of a fire is obviously not going to work as well. Storing the water in a “non-potable” type container clearly marked, one could add the appropriate amount of RV antifreeze to the tank to keep from bursting your firefighting …


Two Letters Re: Advice on Enhancing Cool Basement Food Storage

James: For those looking to create stable and “passively” cool storage in a basement, the book “How and Why to Build a Wine Cellar” by Richard Gold is a well-thought, meticulously engineered solution to many of the same issues faced by those seeking to store food at stable, cool temperatures. Regards, – Ben JWR: I have spent much of my adult life in the construction industry and through experience and educational seminars, etc. I have acquired a substantial amount of knowledge concerning moisture intrusion into structures. Water is the main source of problems in construction. Keeping it in, keeping it …


Letter Re: Advice on Enhancing Cool Basement Food Storage

Mr. Rawles: We are building a new house with a basement. I am planning a food storage room in the corner of the basement that is the furthest underground. Can you guide me with details about how to plan that room, mainly about temperature. I know that cooler is better. The basement has poured cement walls. Should I insulate the [other] two walls [that are partitions] inside the basement? The rest of the basement will be heated, should I leave the vents out of that room all together? What about the vent that pulls air in for circulation? We are …


Letter Re: Advice on Where to Learn Practical, Tactical Skills

1

Dear Jim: As my confidence in the dollar depreciates and my desire for skills increases, I’m wanting to convert FRNs into hands-on knowledge. What weeknight or weekend workshops would you recommend? Are there any places where you can learn Army Ranger skills without joining the military? Animal husbandry, and so on? – Spencer JWR Replies: There is a tremendous wealth of free or low-cost classes available–enough to keep you busy every weekend of the year if you are willing to drive a distance. If you have time and just a bit of money, you can get some very well-rounded training …


Nuclear, Chemical or Biological Disaster Preparedness, by Brian A.

One of the recent phrases the media has used almost to exhaustion is, “dirty” bomb. A dirty bomb, or radiological dispersion device (RDD) is basically an explosive device with some element of radioactivity attached, or some other means of distributing radioactive particulate matter. When detonated, it releases radiation in the form of dust or debris, which is harmful mostly when inhaled, or introduced into the body by other means, (eyes, open cuts, etc.). The main terror use of such a weapon would be to contaminate emergency services workers responding to the initial blast. In the 1990s, Chechen rebels reportedly placed …


Chimney Construction, by PrepNow

I would like to offer some information about my experience with chimney construction and creosote build up. This information does not apply to the typical suburban open fireplace. What I’m talking about is a wood-burning stove designed to heat your home or shelter. There are a number of manufactured fireplaces available that are designed to regulate the amount of combustion air traveling into the firebox and consequently the control the actual burn. These are the most efficient and are the type that we would be using in a structure designed to ride out the future storm. Construction of the chimney …


Letter Re: Observations on the Recent Missouri Ice Storm

Mr. Rawles, I live in Southwestern Missouri. Did you followed the ice storm that buried the Midwest? We got hit pretty hard. We get hit hard every four or five years. Which brings me to my point. I have never seen so many unprepared people in all my life. After day two of the ice storm power was out (for a month in a lot of places like Springfield). There were no gas cans to be found at any store. Batteries, disposable propane bottles, flashlights, milk, and meat were missing from the shelves of every store. Even Wally World [Wal-Mart] …


Letter Re: Observations on the Recent Oklahoma Ice Storm

Jim: Well, I just got back online. I had to go up to the roof and thaw the wireless [Internet] antenna with a heat gun. It seems the ice grounds out the antenna. It was an easy fix with my heat gun for heat shrink tubing. More precipitation is on the way but colder. It will probably just be snow. We never lost power but were ready anyway. I have friends with no power and they have been without power for days and no idea when it will be back on. The further out you live, the less chance of …


Pre-Crisis Survival Skills, by D.A.L.

Pre-crisis survival skills: The only tool more valuable than knowledge is an attitude of self sufficiency. The mere willingness to provide for your own needs can pay off everyday, even absent any “end of the world as we know it” event. In fact, simply being willing to provide for your own needs can pave the way for not only learning valuable skills, but saving money to boot! By way of example let me tell you about a recent experience with the steam heating system at my lady friend’s house. It is a Victorian house and the main boiler furnace was …


Letter Re: First Hand Observations on the Recent Pacific Northwest Wind Storm

Background: I am an 11 year veteran peace officer and survivalist, or in more politically correct terminology, a POP – Preparedness Oriented Person. I work in a moderate sized city in the Seattle area. On 14-15 December, the Tacoma-Seattle-Everett metropolitan area suffered one of the most deadly and damaging windstorms in recorded history. The storm easily eclipsed the last major deadly blow on Inaugural Day, 1993. That storm had been identified as a “once in a century” type storm. At the peak, over 1 million people did not have power. This storm was modeled and forecasted with accuracy five days …
