    The Amazing History of Early Weapons is 120 pages of illustrated articles reprinted from American Machinist Magazine, 1918. 1. Cannon making in past centuries. 2. Musket manufacture in past centuries. 3. Early attempts at submarine building. 4. Some types of modern (1918) hand grenades. 5. Early history of the marine torpedo. 6. Ancient helmet making. 7. The development of gun manufacture. 8. The forerunner of the tank. 9. Fighting with fire in ancient times. 10. Early attempts at rapid-firing guns. 11. Making boring bars for big guns. 12. Intrenchments and the wire barrier.

    This book is reprint from an old magazine, it gives good information, but it is not a step by step assembly guide.  I have used this book to build things, but you have to be able to extrapolate from what they are saying.

    This book came from the now defunct Lindsey books, which was a priceless tool for preppers, DIYers, and the self reliant.  I was very sad when Lindsey decided that the world was now overrun with the stupid and he didn’t want to deal with the public anymore.

    I can’t say that the History of Early Weapons is the best of his books, but I did find it pretty interesting as well as a book full of ideas.  I believe that the handy and smart modern man, with desire and the willingness to work hard can replicate any of the technology of the 1800’s and earlier.

    This means that if you want it, and are willing to do the work any of the subjects in this book can be replicated.

    Which is why, if you dig down to the root, is the reason I took up metal casting.  One day I hope to build my own cannon.

    Thriftyvac Vacuum Sealer Review

    Since oxygen is one of the primary enemies of food storage, preppers, homesteaders, and those living frugally can all benefit having the ability to vacuum seal food. The problem for preppers is that most vacuum sealing options are electrically operated. For the frugal, the problem is that most systems use proprietary bags that are expensive. Homesteaders may have issues with the availability of bags – I know I tend to have a half empty roll of bags when I start to process meat.

    A few months ago, while exploring the kick-starter website, I found a innovative device that solves all of these problems. I immediately sponsored the project, and asked the inventor, Dr. Cannon, to come on my podcast and explain his machine.

    Last month I finally got his thiftyvac device in the mail, and while it was smaller than I had imagined (a good thing), it was every bit as useful as I had imagined.

    Basically the thiftyvac is a fixture that turns a large ziplock bag into a vacuum chamber that allows the user to vacuum seal smaller ziplock bags sealed inside. This is useful because traditional electric powered sealers can only work with their proprietary bags that have tiny ridges molded into the plastic – use something smooth like mylar and they cannot pull a vacuum.

    Since the bag is placed inside a chamber, as the air is sucked out of the chamber pressure is equal inside and immediately outside the bag so that even smooth bags can be emptied of air.

    All you do after the vacuum process is complete is to press the inner Ziploc bag closed.

    Let me tell you, I kick myself every time I see it, as it is so simple and elegant, I wish I had thought of it myself.

    Dr. Cannon stayed with many commercially available parts both to keep prices low and to ensure reliability. One integral such part is the air pump – the thriftyvac includes a small hand powered pump that allows the device to be used without electrical power. I find that not only is the thriftyvac cheaper to use than my food-saver, it is smaller, and much easier to use.

    What is even more impressive is that he did not stop there, Dr. Cannon also invented a new set of mason jar lid adapters, and an adapter to use the thriftyvac with commercial vacuum sealers for those that choose not to use the hand pump.

    I am planning on experimenting with it more and see if I cannot use a mylar bag clamp and my 7mil mylar bags. I also want to see if I can use his pump instead of my break bleeder pump as I like using the mason jar adaptors I bought previously.

    I haven’t received anything for this article, or the 5 star review I posted on Amazon – I bought my own thriftyvac. I just believe in the product, and think that it serves to solve a need that I have had for a longtime. Namely a cheap way to vacuum seal food and ammo when the power is out…

    For today’s show David is interviewing an real-life rocket scientist, innovator, and Hall of Fame athlete Dr. Tom Cannon.

    Dr. Cannon holds 21 different patents – from things such as the fiber optic connectors on the Patriot Missile system, to a bubble level device to help you perfect your golf swing – but today we talk about his ThriftyVac® invention.

    Thirftyvac is a device that allows for the non-electric vacuum sealing of food using ordinary zip-lock type bags.

    As with all innovators, Tom started with a problem, defined it, and then came up with a cost effective and sturdy solution.

    The second I saw his video I knew I would back his project – Not because it is worth it (I think it is), but because it solves problems I have experienced and therefore makes my life easier.

    Dr, Cannon‘s invention is currently being funded through Kickstarter.com, and for those not familiar Kickstarter is a way for innovators and producers to receive funds from actual consumers instead of venture capitalists – this way products either fail or succeed based upon what people actually want rather than how good a salesman you are.

    The kickstarter project for the Thirftyvac is already successful, and Tom has raised enough to ensure his product will be produced.  So I am not having him on the show to help him, as much as to give you the opportunity to back the project so you can get the device and other backer rewards much sooner and at a lower cost than what will be available to the general public.

    His project will close on July 10th at 10:56am CDT, after that you will have to wait for the Thirftyvac to be sold commercially – (early 2014) – backers are scheduled to get theirs before Christmas 2013.

    Besides talking about the Thriftyvac, Tom also discusses his booklet “How to be an Innovator” which explains how to go from a problem to an idea, to a product – and then a business.

    I approached Dr. Cannon because I believe that a non-electric vacuum sealer than is non-destructive to the bags (ziplock can be reused) is something the prepper community could use.  I have not received anything in return for my endorsement.
