RUST – The Enemy of All Car Owners Part 1 – Why Iron Rusts

Rust is the enemy of all car owners. Rust is that nasty brown stuff which destroys the bodywork of our cars, which causes our paintwork to bubble and blister, which is the downfall of our chassis and which causes our car to fail that vital MOT. Rust is the final dust into which our cars will crumble.

Rust is the oxide of iron that results from a chemical reaction: the oxidation of iron by atmospheric oxygen. There are in fact three kinds of iron oxides. These are known chemically as FeO, which is a black powder, Fe2O3 which is a brown-red powder, and Fe3O4 which is a mixture of the other two.

Iron will only rust in the presence of moisture. If you had an iron nail in a jar of oxygen with absolutely no moisture present the iron nail would never rust. Add some moisture and rusting will happen quite quickly, add a sprinkle of salt and it will happen very rapidly indeed.

When things go rusty a quite complex electro-chemical process is taking place. When iron is in contact with water that contains some dissolved oxygen, something called a solution tension is created. This will vary over the surface and will result in different electrical potentials. In the relatively electropositive regions the iron will dissolve forming positive iron II ions. At the electronegative regions negative hydroxyl ions (OH-) are formed. These react with the iron to form iron hydroxides which are insoluble. The iron II ions that are in solution react with hydrogen ions to form iron III ions which react with the hydroxide ions to form hydrated iron oxides. When these dry out they form rust. The greater the initial number of hydrogen ions (the lower the pH) and the more conductive the water (for instance the greater the concentration of road salt) the faster the rusting takes place.

When the rusting process has gone too far, the car parts that have corroded are irretrievable and will need to be replaced. Nowadays it is relatively easy to purchase these online, however prevention is better than cure and in the next article of this series we will examine ways to prevent rust. 

How to Make Your Own Electric Car and Save Money on Gas

Its commonly believed that you need to be a qualified mechanic in order to make an electric car, but as I will show you, this isn’t the case – just some relatively basic tools and a good set of instructions will do.

But you may be asking, why would I want to build an electric car anyway? Well, for one thing, you will save a lot of money. Unless you have been living under a stone for the past couple of years you will have noticed that gas prices have sky-rocketed. Well, electricity is cheap and renewable, its also clean and exceptionally quite, so not only will you save money, you’ll also help to save the planet.
Ok, I’m convinced, what do I do then?

Number 1 – and most important – get a good guide.
Number 2 – many hands make light work – its good to get a friend involved for some of the heavier stuff
Number 3 – get a suitable place to work – make it under cover this job normally takes a couple of days and you don’t want the work stopped by bad weather. Make sure its well lit, in fact, just a normal garage will be fine
Number 4 – get some basic tools- cordless drill, saws, wrenches, maybe a socket set…

Of course its best to also have a suitable vehicle. Small compact cars are best as they are lightweight and relatively simple to convert. A problem with small cars is that the batteries do take up quite a bit of space, but a good guide will show you how to get around this problem.
The parts are all readily available from most auto stores, so that shouldn’t be a problem, but if you live out in the boondocks, there are plenty of places to get the parts on-line. Again a good guide will help here. All, in all, it took me about a week to complete the work, and now my car runs on electricity!

With gas prices predicted to climb as high as 7.00 a gallon by the end of next year, its never been a better time to convert your car to run on electricity.

Classic Cars And Where To Start

The key to investing in classic cars is to know about what your investing in, if you are interested in a certain car to start you down the road spend time on research. What owner clubs are there, are spares reasonably easy to get hold of, and so on.

Are you are a car lover, of a sentimental generation, or simply one who would like a cool ride, buying classic cars is your best bet. Restoring these older cars is probably one of the most rewarding, albeit expensive, of all the hobbies you can take on. But surprisingly, auto insurance for these cars is much cheaper than regular car insurance and is much different than insurance for a regular everyday car.

One of the areas that differs considerably between modern and classic cars is deprecation, buy wisely and appreciation is more likely. Restoration of any of the more mature cars is one hobby that a lot of people have and just seem to sink a ton of money into. Buying and restoring classic cars is a popular hobby for many car enthusiasts but is rarely a straightforward task.

Finding your ideal car, and restoring classic cars is a popular, and also time consuming and expensive, hobby for many automobile enthusiasts.

The mileage and engine is hardly ever an issue as the mechanics of the older cars and classic cars are normally very robust. As with anything, knowing what to look for and where to find it when it comes to scouting out your project car is paramount. The only way that an individual can keep abreast with all activities and events relating to classic cars is by joining the car club specializing in your chosen car.

Finding classic cars is not normally all that difficult but if you need a certain make or model, it could prove to be a challenge. And of course, the most rewarding part when it comes to owning and collecting classic cars is that you get to have a cool ride. Looking back and watching these cars is just like reliving the days when they were still roaming the streets, pure nostalgia. Restoration of classic cars is a wonderful past time for a lot people around the world, but go carefully, your wallet can soon be emptied.

And when you have your dream car, then what? Use it, of course.

Just imagine turning up to, say, a murder mystery night in your new wheels and dressed in period costume, what a start to your night, what a great talking point and you never know you may meet a like minded soul and spend the night talking about your classic and totally forget why you were there in the first place.

Heady days!
