Frequently Asked Questions . . . FAQFrequently Asked Questions @ Mechanical Elements

The best customers are the ones that ask questions.  So, along with all the articles in the The Mechanic’s Post, here are several answers to some common questions.

We understand that many questions are specific, and some answers just spon more questions.  If that’s the case, please Contact Us, and let’s talk about it.

 

  • All the plans at Mechanical Elements are fully engineered at Synthesis Engineering Services, Inc. — an Engineering Services Company in Colorado Springs.  Read more on the About Us page.

  • Each Product page in the Plans Store explains abilities to build the project.  For instance, it might say “Welding and Steel Cutting Required.”  If you can do the things listed, then you have the skills to build the project.

    One note, however.  Some of our projects require welding that is critical to safety.  Please assure that you are sufficiently qualified in welding, or take those portions of the project to a certified welder.  We don’t want you or anyone else hurt due to build problems.  Thank you.

  • This is a question we get a lot, but it’s kind of an impossible answer.  It depends on choices you make when building.  Here are some reasons for saying that:

    1. Cost of raw materials change all the time.  We can’t guess what the cost is for you.
    2. The plans have options.  The options you choose will certainly affect the cost.
    3. There are many levels of components.  If you buy cheaper parts, it will obviously cost less than if higher-end products are purchased.
    4. Some people have access to deals or even some free parts or materials.  We don’t know what discounts you might negotiate in the purchase process.  Always ask for a discount.

    Though we’d love to tell you just how much, we just don’t have enough information to do it.

  • We are in the business of Engineering and Design.  Trailers — and the other DIY projects — are there for you.  That said, we want you to experience the pleasure of building success.  There is a great pride of ownership when you build it yourself — even if it’s not absolutely perfect!

    Though we do build things frequently, we are not a fab shop so our work is not as fast or as skilled as a full-time fabricator.  If you want help, we recommend finding a local, skilled shop.

  • Need help with wiring diagrams for your trailer?  Not sure about what connector to use or how to wire the lights or brakes?  We have the answers all spelled out on our Trailer Wiring Diagrams page, and in this short article about wiring.

  • First of all, yes, we do custom design work through Synthesis Engineering Services.

    Cost to design is obviously a function of complexity and the base for which we can start.  Our custom projects range from a $200 USD for custom additions, on up for complete new plans.

    For example, A typical Tiny House trailer design to meet your specific needs is likely to cost something in the $3000+ USD range.  Other specialty trailers are similar.  That said, the best way to find out is to ask.

  • Again, this is a good question we get a lot, and there are two parts to the answer.

    First, the plans are fully engineered at Synthesis Engineering Services, and will perform as stated — when built as defined with proper materials, skill and care in construction.  Because materials, component choices and construction are beyond our control, trailers cannot receive advance certification.

    Second, in most jurisdictions, the plans do not matter.  Rather, the trailer is inspected for road worthiness and adherence to local laws (axles, tires, lighting, wiring, chains, etc.) after construction is complete.  (As a side note, for tiny houses, we recommend you do the inspection for the trailer before you build the house on it.)

    So, the plans do not have a DOT or other government certification, because the way they are made, options chosen, and components used all go into the final inspection.  That inspection, for most jurisdictions is the point of certification.  Sorry, we can’t do that for you.

  • The Frame is the base of the whole trailer, so make it right first, and that helps everything else.  It is important, so we have a few articles about just that.

    1. Start with “How To Set Up A Trailer Frame Build“.
    2. Next, read “Tips To Strengthen A Trailer Frame“.
  • For this question, like the one above about cost, it’s kind of an impossible answer.  It always depends, and here are some reasons for saying that.

    1. We do specify certain materials, but there are also material options.  Choices change the weight.
    2. The plans have options.  The options you choose will certainly affect the weight.
    3. Most of the plans descriptions have a weight range for the base trailer.  That givez some idea, but again, see the two points above.
  • Axle sizes and details to order the correct axle are contained in each set of trailer plans.  Most plans show options for straight axles and drop style axles.  If available, torsion axles specifics are explained as well.

    For more information about axles, please read the article on Choosing Multiple Axles, and the one about comparing Springs & Torsion axles.

  • A great question.  In fact, that question is so important, we wrote an article about it — including the engineering equations you’ll need to calculate it.   (It’s not that hard).  Please read  Where Does The Axle Go?  Enjoy.

  • Torsion axles apply forces to the trailer frame in a little different way than leaf springs.  (Read about selecting axles.)  Both types work great, but because of the differences, we design trailer frames specifically for the type of axle, and that is seen in the description of the trailer plans we offer.

    We recommend that you follow instructions about using Leaf Spring type or Torsion axles for all our plans.  Please don’t substitute.

    Plans are available in the shop for both Leaf Spring style axles and for Torsion Axles.
