It’s All in the Engineering

A considerable amount of my time in fulfilling the self-sufficiency dreams Rebecca and I have is spent building new items and repairing existing items. Existing equipment of all types requires constant maintenance as well. If you leave a cage exposed to the elements long enough, it’ll simply rot away. Everything has a tendency to fail without some sort of maintenance. All of these efforts—everything from building to maintaining to tearing down when an item is no longer useful—relies on some sort of engineering principle. If you want to get water to your garden, but the hose diameter is too small, the resulting trickle will only serve to frustrate you. Building shelves that don’t rely on proper engineering principles are downright dangerous. Installing electrical elements without regard to the amount of current the circuit needs to handle will almost certainly result in a fire. In short, in order to know in advance just how well something will work and what you need to do to maintain it, you need to know the engineering behind it.

In the Building Larder Shelving post, you learned about the engineering behind building shelves that will hold up to the weight of canning jars, which is considerable. This is just one of many posts that I’ve created that define the math behind self-sufficiency. If you ever find an error in my calculations, please let me know so that I can provide an update with the correct information. It’s also important to realize that my calculations are for a specific project type and you need to use them with your project in mind (making any required changes).

Fortunately, there are other places where you can find interesting information about engineering principles. One of the best places I’ve found recently (as passed on by a friend) is Engineering Toolbox. This site provides all sorts of useful information about various engineering disciplines, including how to create the proper sort of concrete for a project that you have in mind. If you were to mix the concrete without using a recipe, you’d either end up spending way too much money for your project or you’d end up with a project that won’t hold up to any kind of abuse.

It’s incredibly dangerous to take on a building or maintenance tasks for which you lack the proper equipment or training. Always make sure you understand not only the engineering behind the task, but that you also adhere to any required building codes and obtain the proper permits and inspections, as required. More than a few people have gotten hurt by not taking the proper precautions, so always verify that every step of a process you perform is done correctly before you proceed to the next step. The care you take in performing self-sufficiency tasks will always pay dividends in your personal safety and the longevity of the project.

Finding the right site to discover just how to create, maintain, and tear down the equipment needed to be self-sufficient can be an adventure akin to the mysteries solved by Holmes. You need to exercise care in using the information you find and verify that information across several different sites to ensure it’s accurate. Of course, there always comes a time when you’re simply in deep water and need the help of a professional. Some professionals will mentor you in building your project (for a fee in most cases); others will let you help them perform the task so that you gain needed knowledge and experience.

Building and maintaining your equipment can be a lot of fun. However, doing it the wrong way can be a disaster. Let me know your thoughts about building and maintaining equipment at
