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

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

Torsion axles apply unique loads to the trailer frame compared to leaf springs.  Ignoring this can lead to over-stressed components and possibly failure.  A robust design handles the loads, and we’ve done just that.  New trailer blueprints with illustrated instructions are now ready with Torsion Axles.  New plans include utility trailers — a 4’x6′ – 2000#, and a 4’x8′ – 2000# — and an all new 4’x6.5′ – 2500# Off Road with more ground clearance.

Some sites brag about “Engineer Approved” plans.  We’ll do one better . . . these plans are created by the Engineer with full analysis.  Stay tuned, because more sizes are coming.

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.
