Merchant Policy

The following Merchant Policy pertains to the sale of Plans, Products and Services of and — both are sites of Synthesis Engineering Services, inc.  Please also see the Privacy Policy and know that you can Contact Us with any questions.

How to Order

Merchant Policy is PayPalOrder Plans Online:  Follow the link buttons to the items you want, then use a major credit card or PayPal account to place your order.  Credit Card transactions are processed via PayPal or via Stripe depending on the choice made during checkout.

Stripe CC ProcessingPlans are available for electronic download immediately after payment.  This delivery method benefits our customers because it has No Added Shipping or Handling charges – AND customers can receive the plans in just a few minutes.  Speedy delivery, so to speak.

Plans by Email:  Under some rare circumstances where download is not possible, we can deliver plans via email.  Please contact us and we can probably help make the download work for fastest deliver, but if not, email is possible.  (Please allow 3 business days for email processing.)

Plans by Mail:  As of 2023, we no longer provide printed plans or plans via Mail Order.  The need is so rare, and the cost and time for shipping is high.  It is best for customers who want the large format prints to simply download the files, then take them to a local print shop for printing.  It saves customers 2 – 3 weeks for delivery as well as saving the charges for Shipping and Handling.  Printing costs will be roughly the same either way.

Use Agreement

The product design plans offered for sale through or through are for individual use only.  Any use of these plans for resale or for producing products for sale is strictly prohibited.  Licensing for production and/or resale is available on request.  We reserve all Intellectual property rights for the plans and the designs.  We thank you for honoring these terms.

This restriction is not only a part of our Merchant Policy, but customers must also explicitly agree to it as they purchase plans.  Again, thank you for honoring these terms.

Return Policy

All sales for downloaded digital products are final.  Our system shows the download attempts, so if you have not downloaded your order and need a refund, we can make that happen.  Since digital products really cannot “return”, sales for those orders are final.  Please let us know if you have questions prior to purchase.  We are happy to help.

All sales for shipped items are final.  You may request a refund for items not yet shipped by sending an email message to “information” at or via the Contact Us page.  Please indicate the reason for the return.  If you pay for your order by credit card, then we will issue a credit that will appear on your billing statement.

If you have any questions concerning your order, or questions about items in this Merchant Policy, then please connect with us through the Contact Us page.

Plans Format & Printing

Electronic versions of the plans are provided in either Adobe PDF or Microsoft Word format for easy accessibility.  A .ZIP file format is for compression to ease downloading.  If your computer does not already have one, a free PDF reader is available at and a free ZIP utility to unpack the files is at

Most plans have a native format to print on “C” size paper.  All plans can shrink to fit other sizes like Letter size – 8.5″ x 11″ .  To some people, the C size is difficult or expensive to print because it is quite large, so we recommend shrink to fit smaller paper sizes.  If the printing is too small on 8.5″ x 11″ paper, use 11″ x 17″ paper (commonly called Tabloid).  Or use a similar size for customers that are not in the USA.

For special cases where full-size templates are required, files of other types (like PostScript & DXF) are also included.  Send the special files directly to a large format printer, or take them to a printshop for printing.  Read the instructions about DXF files.  They are computer language, not usually for printing, but for cutting out parts via Laser or Water Jet.  All of that is explained in the instructions document contained with the plans.

Product Performance

All product designs at Mechanical Elements are fully engineered to perform as stated.  However, construction methods, materials, assembly techniques and/or skill of the craftsmen may adversely affect the functional outcome.  Please follow all directions, including material and component specifications carefully.  Because your material choices and manufacturing techniques are outside our control, we cannot warrant products or guarantee the performance of items made from the plans.
