Where Are Castors Used In Motor Racing?
Article by Marvin Maloney
For most folks, and you may very well be one of them, when they watch a motor racing event it’s just so easy to assume that the only wheels that are involved are the big wheels on the vehicles that the drivers are operating. The real truth of the matter, however, is that if you were to look behind the scenes, for instance in the shop where a vehicle is maintained, you would find loads of much smaller wheels in the form of castors. Castors are used to expedite a huge assortment of tasks; to speed them along and also make them so much easier.
For instance, so many of the components that make up today’s high-performance motor sports cars are really quite delicate. Sure they take a beating when they’re on the track but that’s after they’ve been bolted into the car. On the other hand, parts and even entire motors, once they’re removed from a vehicle have to be moved about on a cart with castors, so they don’t get damaged.
Then if you were to take a look around the shop where the vehicles are kept and maintained what you would find is that so many of the tools and machinery that are used to keep them in top working order are on castors. Consider a tool box full of hand tools for instance, that can easily weigh hundreds of pounds. It only makes perfect sense that it should be rolled over to the vehicle, so all the various hand tools are within easy reach of a mechanic.
Then on race day if you were to take a walk over to have a quick look at the area where the pit crew operates you are sure to find that almost everything there is on castors for convenience sake. Not only does it make all the necessary equipment faster to move which is important but the castors also make the tasks easier, and that for sure is just as important.
This is because the pit crew is only there temporarily. They come in and set up and then when it’s time to leave, after the race is done, castors make the job of packing up just as quick and easy.
Jacking castors make it a heck of a lot easier to get things in and out of a truck or trailer. Also who hasn’t witnessed jacking castors used on a race car to quickly change tires after it’s pulled in for a pit stop.
Take a walk around the racetrack facility, and you would find castors being used extensively from one end to the other. The food concession carts for example, all of the tools for the ground cleaning crew, and even all the tools of the trade for emergency safety personnel will be up on castors to make their jobs easier.
So the next time you go to the races or decide to watch them on TV, why not just for amusement’s sake take on a challenge to see how many areas you could see castors being used as the event unfolds.

Types Of Electrical Conduit Used For Protection And Routing Electrical Wiring That Produces Electric Power
Article by Richard Kenny
An electrical conduit is an electrical piping system used for protection and routing of electrical wiring that produces electric power. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Flexible conduit is available for special purposes.
An electrical conduit (EC) is a piping system that is used to carry electrical wiring for either power or communication. These piping systems are commonly referred to as raceways. The EC’s are solid and they are used to both house and protect electrical cables and wiring. EC’s may be made from a variety of metal’s, plastic and fibers. Some of these varieties are available in flexible forms for your special need and run in 10 foot increments. Here is a list of your most common EC’s.
Rigid Non Metallic Conduit (PVC), PVC is made from a combination of both plastic and vinyl. PVC pipes can be installed above ground, underground or encased in cement. PVCs are most commonly used underground. These pipes are light weight, flexible, impact resistant, non conductive, ultraviolet resistant and corrosion resistant. They are popular because they have watertight joints and low installation costs. They are not interchangeable with other EC’s.
Rigid Metal Conduit (RMC) / Rigid Steel Conduit (RSC), RVCs and RSCs are your heaviest and thickest option, typically made of coated steel, stainless steel, red brass or aluminum. These pipes can be installed above ground or underground. They are similar in appearance to metal water pipes and are threaded at both ends. The threads on the uncoupled end of the pipes are covered by industry color-coded thread protectors, which protect the threads, keeping them clean and sharp. Although RMCs and RSDs are generally corrosive resistant, a layer of PVC or zinc (see GRC) can be added in areas that are wet or highly corrosive. If you opt for an organic coating you check for heat restrictions. These types are interchangeable with GRCs.
Intermediate Metal Conduit (IMC), If you opt for an organic coating you check for heat restrictions. They are interchangeable with GRCs.
Galvanized Rigid Conduit (GRC), GRCs are created by taking one of your above RMC, RSD, or IMC and galvanizing it via hot dipping it in zinc. The zinc coating provides extra coating in areas that are wet, or highly corrosive. GRCs are interchangeable with most RMC, RSD, and IMC to use when only an area of your piping is in need of additional protection. PVC coating can be added on top of GRC coating for ECs that will be exposed to chemicals and other highly abrasive materials.
Type 5 – Electrical Metal Tubing (EMT), EMTs are not interchangeable with other ECs. And the flexible Metal Conduit (FMC), this is your option for areas that need to sustain large amounts of movement and vibration. They are found with stainless steel, galvanized steel or aluminum. They are available as water proof if needed and are installed above ground. The appearance is similar to that of metallic armored cable. They are often used when wiring motors and are not interchangeable with other ECs.
Richard Kenny suggested to look for licensed and reputable electrical contractors for your electric power and other electrical problems.
New and Used Motor Home RV Values – Blue Book and NADA
Article by Nina Romanov
If you are interested in purchasing a used motor home or have a used RV you want to sell there are some things you need to know about the Kelley Blue Book and N.A.D.A. guides.Unlike the guides for automobiles which are based on analyses of actual car prices, the Blue Book and NADA guides are based primarily on a percentage of the manufacturer’s suggested retail price (M.S.R.P.). These guides may be nowhere near the actual current resale value.
The guides include many options in the M.S.R.P. so it is hard to know which, if any, options you should include. This makes it easy for options to be charged twice.
A better way to find the resale value of RV’s is to look at other mobile homes of the same class, make and model. Check for similar amenities and base your price on that.
If you are looking to buy a used RV, these comparisons can help you determine if the price quoted to you is a fair and reasonable price.
Motor home RV values should be based on actual selling prices of similar mobile homes, taking into consideration factors like age and overall condition. Are there dents or leaks? Has the unit been properly maintained on a regular basis? Do all of the appliances work?
If this is a motorized rig, what is the mileage? Is it above or below the average? Does it run well for the mileage?
Check all accessories that came with or were added, such as the air conditioner, satellite dishes, back up mirrors, awnings, solar panels and kitchen appliances. Does it all work?
If you are selling your rig, making sure all of these items are in good condition can greatly increase your selling price.
Use the Blue Book and NADA values as a starting point and then adjust your price, or offer if you are buying, up or down according to the condition of the RV.
You can increase the value of your motor home by sprucing it up. Add new curtains, makes sure it is spotless and update appliances. These simple maneuvers can add hundreds to your selling price.
There are many variables in motor homes to be considered. Is it a towable or motorized? How many can it sleep? What appliances are included? What does the maintenance record tell you?
If you have a late model motor home to sell, you may want to have an appraisal done to insure that you bet the best price possible. Some large RV dealers provide this service and will even broker a deal for you for a small fee.
The type of RV you want to sell or buy also has an influence on your profit or cost. Obviously, a luxury motor coach will garner a larger selling price than a travel trailer or pop-up camper.
As a potential buyer you need to just decide how much you can spend for an RV, what type of motor home you want and what amenities you consider necessary, than with all of this in mind start looking around.
There are dozens of online sites you can browse and check out the class of mobile home you want. Many of these sites have interior and exterior pictures along with a list of amenities.
Of course you will want to find a dealer in your area so that you can physically inspect the used rig yourself before you buy. Ask to see the maintenance record if available. If you are buying from a dealer ask about a warranty.
The Blue Book and NADA guide are useful tools as a starting point. You need to take into consideration the age and condition of the unit, as well as amenities available.
