Announcing  –  Our Newest Blueprints
Utility Trailer Plans Designed Specifically For Torsion Axles

Again, You Asked, and We’re Delivering!  Two new sets of DIY utility trailer plans are now added to the Mechanical Elements project store.  These are new, but modified and engineered to handle all the differences of torsion axles.  These designs provide a great ride with great strength on rubber.  < Read More >

As we continue to say, there are some unique ways that trailer loads distribute on a frame with leaf springs as compared to torsion axles.  Ignoring them can lead to over-stressed components and possibly failure.  To make the trailer robust, the design must handle the loads, so we’ve done just that.  We now have Blueprints with illustrated Instructions for new 4’x6′ and 4’x8′ torsion axle utility trailers.

Some sites brag about “Engineer Approved” plans.  We’ll do you one better . . . these plans are created by the Engineer with full analysis and they are ready for you to start building.

Stay tuned, because there are more sizes to come.

Blueprints for your next project — A fantastic Trailer, a Gantry Crane or a Storage project.
When you Build It Yourself you can Make it Better and Customize it to be perfect for you.
