The Assembly Fixtures
Along with the development of the DOTT trike, assembly fixtures were also created. These four fixtures allow each part of the frame to be held in perfect alignment during the welding process. They simplify the most difficult part– construction–making it possible for some to build such a trike in as little as 10-25 hours.
These fixtures, along with a welder, tube bender, notcher, drill and various smaller tools are enough to equip a trike manufacturing shop for production. A reasonably experienced welder is recommended. All other production operations can be learned relatively quickly.
Drawings And Documentation
HWI can make many types of documents and drawings available to support trike production:
• Pictures • Standard blueprints • Exploded assembly views • Individual part drawings • Bill of material • Parts sources • Fitting manual
If desired, a highly detailed 3D AutoCad model of the trike is available.
Production Training
HWI is currently producing a trike assembly video. Future plans include a week-long “Trike Building Experience”training course available to those who can come to the Chicago area.

In the picture above, a complete DOTT assembly fixture set is shown. The round tubing seen on the large fixture is a trike chassis ready to be welded together.
HWI has many schematic drawings available to support trike production. This example illustrates the major components of the DOTT Frame.
