Home Security–The “Lock Bumping” Threat

There is currently a lot of buzz on the Internet about the emerging threat of “lock bumping.” This is an old technique used by burglars that can defeat up to 80% of typical household dead-bolt locks. It is catching on with a whole new generation of burglars in the U.S., Canada, and in Europe. (Using an easily obtained specially cut generic “bump” key and a small mallet.) This video clip from Holland (with English subtitles) shows the technique. And here is another video, from here in the States. My advice is to upgrade the locks on your exterior doors with …




Letter Re: New York Military Bunker on eBay

Hi Jim, I can’t say I see many bunkers for sale on eBay. I personally don’t consider New York state ideal for a retreat location, but it is interesting to see this property available nonetheless. I’d be a little concerned about potential HAZMAT issues. BTW – I’m really enjoy reading Rawles on Retreats and Relocation. I’m in between “permanent” dwellings at the moment and it helps to have such a resource when considering my options. Kind Regards, – M. Artixerxes




Letter Re: Advice on Underground Retreat Construction

James: I agree with you Jim; your own home is not a first time DIY project, but. I would also refer Buddy to the $50 and Up Underground House Book. I have the book, and the author’s DVD/Video set. The book covers the construction method pretty well, and the DVD/Video, while not studio quality, is clear, has lots of models to illustrate his points. If I was going to build an underground home myself, this is the route I would take. Also, even though I have a significant amount of experience with construction, I would still spend at least a …




Letter Re: Advice on Underground Retreat Construction

Sir: I have 40+ acres, all wooded. I want to build a shelter. There are plenty of hills that I can dig in to, build the shelter and then cover it up. but I don’t know a thing about building a shelter. I need to know everything. From making it water tight to air venting. Where can I go. I do not want to buy a shelter. I want to build it my self. Thank you, – Buddy JWR Replies: Building an underground house, a retreat, or just a simple below ground cache that doesn’t become an underground cistern is …




Letter Re: A Retreat Construction Alternative–Grancrete

Hi Jim, I saw this today and thought it was a very interesting construction technique: Grancrete. I also saw a site on sandbag construction some time ago and I thought that it was also interesting Either one could be used to construct a low cost shelter that could range from “bullet resistant” to “bullet proof”, depending on thickness. The grancrete could even be sprayed in successive layers to develop the desired thickness as it will adhere to itself unlike concrete. I hope that you and yours have a wonderful Christmas and a happy and prosperous 2007! Regards, – Tim P.




Letter Re: Pepper Spray Trip Wire Alarms

Dear Jim: Nothing beats living at your retreat, but there is one burglar repelling device that can actually stops a burglary in process (without an alarm or monitoring): Pepper Spray Alarms – either trip wired or set off by electronic sensor. These can fill a room with pepper spray in seconds. You can even get one that can fire up to four times in sequence! I have used them (and tripped them accidentally). They really work – and it only takes about an hour of ventilation to get back in the room comfortably. As an added bonus you get to …




Two Letters Re: Build Your Fallout Shelter From Barter Goods, by Mr. Yankee

Jim: Regarding Mr. Yankee’s article: Salt in some water softeners is potassium chloride, not sodium chloride. Both are ‘salts’ but they behave differently. Be sure you are storing the sodium chloride variety.- SF in Hawaii   Mr Rawles, Hope this finds you and your family doing well. I’m not sure if this link has been disclosed in the past, and I am certainly no expert in this field, but this seems like a well thought out presentation for a fallout shelter. Keep up the good work, – R.C.




Three Letters Re: Build Your Fallout Shelter From Barter Goods, by Mr. Yankee

Hi Jim. Just felt the need to re-emphasize the point you made with regard to Mr. Yankee’s ideas about an improvised fallout shelter. First, I applaud his view that one should not count on being able to pull together an adequate expedient shelter when the need arises. As simple in theory as it seems, in practice, few would end up with a shelter they would want to rely on to save the lives of their loved ones. Second, as far as the point you made, Jim, it is indeed very important to over-engineer any sort of structure that will be …




Build Your Fallout Shelter From Barter Goods, by Mr. Yankee

I am just paranoid enough in this uncertain world to think that I’d be better off with a fallout shelter than not. Oh sure, you can throw together an expedient shelter in a few hours, but I think I’d be farther ahead adding some mass to the ceiling and walls of a basement room. Here’s how I plan to do it and I think the plan will work for anyone with a similar situation. My basement is of poured concrete with no interior walls. My shelter will be created by converting the most earth shielded quarter of the basement into …




Letter Re: 12 VDC Wall Outlets and Power Cord Connections

Jim, For anyone using 12 VDC in their vehicle or home, you should strongly consider using Anderson Power Poles. Compared to the standard cigarette lighter plug, these are far more reliable and safer. (Cigarette lighter plugs have no uniform rating, and can melt if used for high [current] load applications.) These connectors come in ratings from 30 Amps (A) to 350 Amps. The 30A size is the de-facto standard for Ham radio operators now, and the larger sizes are what you see used for things like large battery racks in computer rooms and tow truck jumper cables. They are easy …




Letter Re: Prowlers and Lighting

Jim: What do you and your readers suggest for someone living in a rural area who needs a good strong light for prowlers? I live on top of a mountain in a cove surrounded by three sides by hills. On occasion, we have trespassers at night riding the ATV trails along the hills who are out to steal tools, gas, etc. There have been more than a few occasions when I’ve walked out to my car late at night to get something and realized there were people in the trees. One night I turned my rather anemic Surefire 6P [flashlight] …




Letter Re: Clothes Washing Without Grid Power

Shalom Jim: Recently my wife and I have started looking to replace our old [clothes] washer and dryer machines with something more energy-efficient. Since we plan on converting to solar photovoltaic panels in the future what do you suggest we do now? 1.) Lehman’s sells an AC +/ DC operated washer. Is this (DC) feature conducive to solar technology? 2.) What are you and your family doing for your clothes washing needs?

Letter Re: Emergency Shelter Air Filtration

Hey Jim, Just a couple of articles [over at the Alpha Rubicon site] that you might find interesting: Safe Room Fan and, HEPA Filter Regards, – S.C.

Letter Re: Tire Spikes for Home Retreat Defense

Hello James, In regards to the recent post toward driveway security strips, or "spike strips" I think of another possibility to the construction in using a 2×6. I would consider fabricating the base out of treated 3/4" plywood. Not only is this already somewhat camouflage, it will take the years of abuse that weather will give it. I envision a design in which the upper three or four layers that are glued together with construction adhesive, (preferably a polyurethane adhesive like PL Pro), and then drilled for insertion of spikes. Then, apply an additional layer with a width of approximately …




Letter Re: Emergency Shelter Air Filtration

Most of the modern home vacuum cleaners have pretty decent high efficiency particulate air (HEPA) filters in them nowadays. Assuming you still have power (a big if) you could seal a room to the best of your ability and leave your vacuum cleaners running (with the air intakes off the floor). If you have a bag type, remember to put a new bag in. Presto, filtered air, McGyver style. If all you have is an older style vacuum cleaner with no filter, then put a damp rag (and keep it damp) over the air intake, but be careful not to …
