Key elements in modeling

We know that glues and adhesives are indispensable for all kinds of projects, from assembling a model airplane to putting up a wall. While some, like the library paste that generations of children have sampled, are harmless, others contain toxins that can make you sick.

Glues and adhesives come in many forms. They include epoxy, instant glue, plastic adhesives, rubber cement, and white glue. When solvents are added to thin out naturally thick glues, a problem arises in that when the solvents evaporate after the glue is applied, toxic vapors fill the air. When the solvent is water, as in nontoxic glues, the vapor is harmless. But the compounds used in contact cement, epoxy, instant glue, model glue, and rubber cement, among others, are potentially hazardous. They contain chemicals that can irritate the eyes, throat, and lungs if inhaled and can burn the skin on contact. These include acrylonitrile, formaldehyde, ethanol, naphthalene, phenol, toluene, and vinyl chloride. Toluene, for example, has been linked to kidney problems. Formaldehyde, phenol, and vinyl chloride, on the other hand, are suspected carcinogens.

Before using any glue or adhesive, read (and heed) the manufacturer’s instructions. And try adhering to these few safety precautions:

– Never use glues near an open flame.

– Don’t use toxic adhesives on items that will come into contact with food, such as plates.

– For large projects that require toxic glues, wear long-sleeved shirts and pants, goggles, rubber gloves, and a respirator (available at hardware stores).

– When using toxic glues, don’t wear soft contact lenses; they can absorb solvent fumes.

– Always use glues in a well-ventilated area, and replace the cap or lid tightly after applying the product, even during frequent applications.

– You can dispose of nontoxic glues and instant glue in the regular trash, but save spent containers of other adhesives for hazardous-waste collection.

– Instant glues bond instantly, not just to target surfaces, but to skin as well. If this happens, call a poison control center or doctor immediately. When using this kind of glue, be especially careful not to touch your mouth or eyes with your fingers.

Modeling – Vital Info

Today’s kids are nuts about all things electronic. It can be hard to find toys in the store that do not require batteries for one reason or another. Kids get excited about portable game systems, cell phones, and laptops, but those should not be the only things with which they have to play. You have to find some things that do not take batteries, and that require them to concentrate on something for more than a few moments while also challenging their imagination and skills. Think about finding time to build model airplanes with your children. The chance to build model airplanes with your children can come pretty early. A two year old certainly does not have the skills or the patience (or even the understanding) to do this, but a four or five year old can get into the fun with you if you choose something simple with which to start. Get something that they can snap together with you that does not have a lot of parts. You can try one that you have to glue and paint, but it should still be something with few parts. At this point, their attention level is low, so you want something that can be started and finished quickly. The sense of accomplishment will encourage them to try it again. Our Site :

As they get older, you can get them more intricate models. In order to build model airplanes that are more time consuming, they have to have a longer attention span. They also have to know when they have had enough so that they can put it down and come back to it when they want to finish it up. These models should have more parts, but should not go above immediate level in difficulty. These should be glue models, not snap models, and should always be done with mom or dad for the bonding of the experience, at least the first few times. A child that has gotten a bit older, you can build model airplanes that are much more complicated and take much more time. You will know by then if they are really into the hobby or if the are just keeping you happy by building airplane models with you. Get highly difficult and intricate models that require a lot of work and attention to detail. These will keep them busy and help them settle down to get a task done and down well?something that seems to be missing from the younger generations these days.

You can encourage this type of hobby by not only taking the time to build model airplanes with them, but by also helping them display what they have accomplished once they are done. You can get display cases to set them on the shelf in your home, or you can get fishing wire to hang them from the ceiling in their bedroom as a great room d閏or item. Even if they are not doing so well from the start, you can encourage creativity and less technology throughout the day by showing them their hard work is a treasure to you.

Modeling – Things to consider

Here is the first in a series of articles on building scale models. Let’s start with the basics, selecting the right kit. The first, and most fundamental, thing is to pick something you like, that you are interested in. That way you will keep your motivation throughout the build process. If you pick, for example, a sci-fi model, but your interest is in military ships, but you buy the model ‘because it’s the only one they had’, or in your price range etc, then you will struggle to get motivation to start it, let alone finish it. The second important thing is the skill level of the kit. This varies between manufacturers – some have a better reputation for parts fitment than others. Do your research on these before purchasing your first kit. The last thing you want is to spend your money on a kit that becomes too difficult to complete, or you lose your motivation due to bad parts fitment. Don’t rush out and buy a kit that has all the bells and whistles as this will have an adverse affect, start with a basic model, with a low parts count.

So we are at the point where you have decided on the model subject, and selected the kit you are going to build, but what with? You need tools! This is where things can start getting expensive – as there are unlimited tools available for the model maker. But remember, we are starting at the beginning with the basics. You need some cutters to remove the parts, a sharp knife or file to trim the parts, glue to hold it all together, and a paintbrush (or variety) for, obviously, painting. Next you will need some paints and appropriate thinners to clean your paintbrush.

Don’t try to rush the process of building your model, you are more likely to make mistakes that way, and not enjoy it. This is a hobby at the end of the day – you are meant to enjoy it. So now it’s time to start. You have your model, you have your tools, and you have your paints. You may have seen this kit that other people have built. The last thing you want to do is try to copy them, or compare your work with theirs. This will only lead to frustration and negativity if the results you get don’t look as good. It doesn’t matter, your enjoyment and satisfaction in what you have done is the only important thing.

So let’s get to work. Start off by studying the instructions, and finding the parts on the sprues. Familiarise yourself with how the manufacturer has drawn the diagrams, and instructs you to put it all together. Go through the whole manual so you are familiar with it, and how each section fits together. If you follow the instructions step-by-step you shouldn’t run into too many difficulties, but you need to understand what they want you to do before you put the glue to it. Once you are familiar with the instructions, take each section at a time. You will likely find that each section has a number of parts in it. It is generally recommended that you wash all the parts before you start. When they are made, a release agent is used to easily take the parts out of the moulds. You want to remove this, as it can stop the glue and paint sticking correctly. Use warm soapy water for this, and rinse it off properly. Don’t use hot water as this can distort the plastic. Normal dish washing soap is fine for this.

Any parts that become one structure, such as an engine block, can be assembled before painting. Other, smaller parts, you may find easier to paint while still on the sprue. Carefully cut the parts off the sprue with either a pair of side cutters or a sharp knife. The use either the knife or file to smooth the point of removal. You are then ready to glue. There are a variety of glues available, but we will assume you are using basic polystyrene cement. This glue works by melting the plastic parts together creating a strong weld. This glue only works properly if the parts are clean and free of grease and paint. Before applying any glue, check how the parts fit together (dry fit) as a test run so you are familiar with any attachment points that require glue, and how to fit the parts. This will prevent any mistakes being made by having to redo after gluing.
