Trailer Plans-Blueprints

About Our Trailer Plans... All of our trailer plans have been drawn by Dr. Bill R. Long, who has been associated with the trailer and welding industry for over 30 years. As a Mechanics instructor at Stephen F. Austin State University and fabrication consultant, Dr. Long has gained insight in the manufacture of utility trailers. Combining this experience with AutoCad he has developed outstanding shop drawings for those who wish to build their own trailer. Each set of plans has a full bill of material combined with a clear step by step approach providing a cut and supply list in each step. Dimensions are given for every detail, showing 3D views, exploded views, and enlargements where needed to clarify cuts and procedures. Welding tips are presented to minimize heat distortion and maximize quality. All of the trailer designs are proven, road tested, and Engineer Approved. All of our plans have a common purpose; Save you Mistakes, Time & Money!!! These plans are not just drawings, they are plans with a strategy and procedure that give you the benefit of years of experience.
