We found a great little video on YouTube by user “Make:” which in just three minutes (before credits) gives all sorts of great tips for the DIYer using acrylic in their applications. It starts off with a good point that not everyone knows: acrylic comes in both cast and extruded forms. Yes, they have differences that are important in an application. Yes, there is a difference in cost. Other important tips include how to thermoform, glue, and most importantly – drill, the plastic. Drilling is especially important as the plastic can crack easily, so using lubrication and a soft touch is essential to prevent a wasted part. It will help you answer some questions you didn’t even know to ask prior to diving in: do you have all the materials you need? How are you planning to smooth the edges of the acrylic?

We’ll let the video do the rest of the talking:

So…You have a project. You’ve decided that you’re going to use “plastic” for it. Ok, which kind?

Sometimes it’s obvious. Plastic “do-it-yourselfer” applications that involve piping probably involve PVC since it’s so readily available and inexpensive compared to the alternatives. Same goes for acrylic or polycarbonate – the two primary clear (glazing) plastics. But sometimes there are more choices especially as the application becomes more vague. Common plastic applications taken on by amateurs include wear strips, bumpers, sheaves, pulleys, wheels, shock absorbers, ramps, bushings and everything else you can think of. With the array of industrial plastics available these days – how do you select the right plastic?

Well, the easiest way is just to ask. A reputable distributor will be able to take your information and make a recommendation; however, the more information you bring to the representative – the more he or she can help you. Many of the questions you ask should be the same as any of our industrial customers would ask. And we can help you out right here!

Questions you should know the answer to before approaching the plastic distributor:

What is the project?

What is the operating environment? (temperature, any chemical or weather exposure – exposure to UV light is of special concern)

What load or pressure does it bear?

What properties are important in your application? (stiffness, ease of machining, low friction, high friction, etc)

What is your budget?

Based on that information we can help you select a material that will suit your project’s needs.

Plastic built the modern world. Where would we be without bike helmets, baggies, toothbrushes, and pacemakers? But a century into our love affair with plastic, we’re starting to realize it’s not such a healthy relationship. Plastics draw on dwindling fossil fuels, leach harmful chemicals, litter landscapes, and destroy marine life. As journalist Susan Freinkel points out in this engaging and eye-opening book, we’re nearing a crisis point. We’ve produced as much plastic in the past decade as we did in the entire twentieth century. We’re drowning in the stuff, and we need to start making some hard choices.

Freinkel gives us the tools we need with a blend of lively anecdotes and analysis. She combs through scientific studies and economic data, reporting from China and across the United States to assess the real impact of plastic on our lives. She tells her story through eight familiar plastic objects: comb, chair, Frisbee, IV bag, disposable lighter, grocery bag, soda bottle, and credit card.

Her conclusion: we cannot stay on our plastic-paved path. And we don’t have to. Plastic points the way toward a new creative partnership with the material we love to hate but can’t seem to live without.

Now that grocery stores are using fabric bags for shopping, our plastic bags are accumulating under the kitchen sink. If you Google the internet for items made of out plastic bags, the search results are limitless. One that caught our eye was the messenger bag. There is a video on YouTube with step-by-step directions on creating this bag.

Not that we had anything to do with the production of this vehicle but we had to make mention of this engineering plastic marvel. It really goes to show how nearly anything is possible with plastic.

No matter what the project or application – there is likely a grade of plastic that will out perform and outlast metals and rubbers..
