Letter Re: Cinder Block Safety Concerns

JWR, First of all thank you for your blog.  I have been reading it every day for the last year. J.D. in Texas offers some good information regarding Concrete Masonry Units(CMUs), however I may be able to share some more details.  I have also been in the concrete masonry business for about 22 years.  The first thing to consider when using concrete masonry is to avoid breathing any dust from the units, such as when a unit is cut, split, or ground.  At the very least use a N95 or N99 dust mask.  If you are cutting a CMU then …




Letter Re: Cinder Block Safety Concerns

JWR: I have read plenty of entries on your site about people using concrete block (“cinder block”) for square foot gardening and raised bed gardening.  I didn’t know how to post this so, I thought I would just email you this information.   I have been in the Concrete Masonry Unit (CMU) (Concrete Block) industry for almost 11 years.  I started as a yard hand and have recently worked my way up to Plant Manager and Site Safety Manager (two hats due to downsizing and the economy).  I see many people write about using these CMUs or cinder blocks to …




Letter Re: Another Way to Protect Your Retreat, by E. E.

Hello, E.E.’s primary problem was not the insurance. It’s the design flaw and negligence that allows the small glitch to evolve to the full-scale catastrophe. Every trouble that can occur occurs. Every trouble that cannot occur occurs too. Firstly, the furnaces may fail – it’s quite normal. I have no idea about their model but I believe they should have and so have some security automation that stopped them due to some problem (electricity?), or the fuel supply failed. The first task to design should be “The stopped furnaces should not self-destruct”. How should it be done? I see at …




When Push Comes to Shotgun: Survival in the Suburbs, by Michael K.

To anyone who swatches the news or opens up an internet browser from time to time, it’s exceedingly clear that the world is becoming an extremely dangerous place.  From the abstract threats such as global economic collapse or pandemic to the more concrete ideas of natural catastrophes, terrorist attacks and the like, it’s obvious that preparedness isn’t just something to think about occasionally, it’s an absolute necessity.  Yet, with our feet firmly planted in the middle class, my wife and I don’t exactly have the money to go out and build the fortified bunker of our dreams for the day …




Buying a Used Wood Stove by Sid S.

Near the top of the List of Essentials is is keeping warm. One surefire way to do that is with a wood-burning heat stove. Wood stoves are reliable as a main source of heat or as backup but can cost between $1,000 and $2,000 new, so buying used is a practical way to go. Before you buy however, there are a few things you should know. First of all, you need a good, certified wood stove. Why certified? Because they use less than half the wood that the previous generation of wood stoves used, don’t exhaust clouds of unburned soot …




A Secure Compound, Off Grid, by Steve R.

Listed below are mandatory needs, issues and items needed to successfully survive and weather any major natural disasters, deadly germ outbreaks, or government invasions such as martial law. This is a basic outline and your needs may differ according to location, elevation, and of course finances. Money is the root of all evil, but you will definitely need some to accomplish your survival goals. Land and water are virtually priceless. The first and foremost thing needed to build a survival compound is water and land. Land as far away from large cities is ideal. Either find a piece of land …




A Rural Community Retreat, by Scott L.

Location is the most important thing to consider when developing a plan for long-term habitation in a TEOTWAWKI setting. Of primary concern are Community, Safety, Water, Food, Sustainability, and Natural Resources. It is absolutely imperative to find a locale with a well or fresh water spring. You will need fertile ground that is within distance of easy irrigation. The safest places will be those that are away from major highways and population centers; however, these small rural communities are typically suspicious of outsiders. You will need certain natural resources available as well to guarantee you are not reliant on trading …




Letter Re: Upgrading Your House Window and Door Security

Mr. Rawles: Although filtered HVAC systems make for comfortable and healthy inside air quality, even the most efficient draw heavily on AC mains. Insulated airtight walls and windows reduce heat loss and in windy areas reduce dirt infiltration. I would never consider powering a cooling system with solar power but heater blower motors can be so powered. This works well for dual stage furnaces that switch from heat pump to natural gas or propane for emergency heat. Fireplaces are as old as houses but rather than just building any old firebox, I researched fireplace design. When building my ranch headquarters …




Letter Re: Earthquake Resistant Residential Architecture

Hello James: Attached is an e-mail I sent to my daughter.  Her boyfriend is from Honduras and she dreams of doing missionary work there.  I thought it may be of interest to some of your readership.  I left out a great deal of information on building site selection (her boyfriend already owns five acres) and foundations.  There seems to be differences in opinion regarding firmly anchored and sand-bed isolation between footings and walls.  Most of my information was gleaned from the book Technical Principles of Building for Safety (Building for Safety Series) by Coburn. Dear X.: I did a little …




Your Earthquake Audit, by M.B.S.

We are survivalists who live on a hobby farm within The American Redoubt. In the 23 years we have lived in this region I have yet to feel the ground shake beneath my feet. That’s welcome news speaking as a former Californian who has been through two “big ones”. Yet, for whatever reason (the Holy Spirit, possibly) I began thinking about earthquakes two months ago. Because of this mind set, when three earthquakes, southeast of us, occurred in Utah around the 13th of February and the next day a magnitude 6.0 quake hit off the coast of Oregon. That got …




Letter Re: Upgrading Your House Window and Door Security

James, In response to this posting, while something is better than nothing, I am not a fan of putting up anything on windows or better screws or latches for doors or a covering for windows unless it really adds to equation and the cost is reasonable for the return on expenditure.   As an example, a neighbor added a steel frame with mesh, its costs was about $6,000, it is very pretty with double sided keyed deadbolt and heavy latch/striker plate.  Their security factor went way up, sadly the burglars decided to enter from the side yard and wrapped a concrete block into …




Upgrading Your House Window and Door Security, by Happy Hal

My darling wife read the article on Lexan and asked me to contribute the following. My professional specialty lies in the area of windows and doors. How to Prepare Doors Replace the short screws (3/4″) in the door lock plates with longer ones minimum 3″ but 4″ would be better. The 3″ are # 8 but the 4″ are #10 almost twice as strong. There are two each on the strike plate of the depress plunger and two for the deadbolt. These screws enter the studs making a considerably stronger safety connection than short screws that only penetrate the light …




Letter Re: Lexan for Bulletproof Windows

Dear James, I have recently purchased raw land to build my retreat. Soon I will begin building a home, and wish to equip it with windows which can resist small arms fire. I can obtain Lexan in 1/2″ thickness, and my question is, will I need two pieces of glazing in each window, or three (or more)? I do not think it likely that I will be shot at with anything larger that .50 caliber. Your thoughts on the matter are most welcome. Thanks, – Zoomer JWR Replies: To begin, I must warn readers that acrylic Plexiglas and polycarbonate Lexan …




Letter Re: Hidden Entrances, and Secret Rooms

If you do a web search for “hidden entrances” or “secret room” you’ll see some photos and video of various novelties like bookcases on hinges and stairways that open up to reveal hidden rooms behind/under them. While these can be a lot of fun before SHTF, especially for kids, I just wanted to put out a warning that these types of entrances aren’t really concealed at all in a TEOTWAWKI situation. For starters, if you found these solutions on the Internet, then bad guys can find them too. Even if they didn’t do their online research beforehand, you can bet …




Letter Re: Greenhouse Heating

Dear Jim, I was very interested to read about the heated greenhouse in this article. I wondered if people have also tried insulating a greenhouse and designing it to maximize solar gain? I’ve seen a design used in the Himalayas which allows them to grow vegetables throughout the year despite -25C conditions, designed by the charity GERES. I uses a UV-resistant polythene sloping roof facing south, high-mass insulated walls to store the sun’s heat and keep it in, some internal walls painted black and others white to help the solar gain, and finally a manually controller ventilation hatch – though …
