The first phase of assembly involves the preparation of the drawing surface and the installation of the horizontal aluminum extrusion, known as the track rail. The user must begin by ensuring the drawing board is clean and free of debris, as even a small particle beneath the track can compromise the machine’s alignment. The track is typically secured using C-clamps or a specialized bracket system located at the top corners of the board. During this step, it is imperative to use a precision straightedge or a level to verify that the track is perfectly straight and parallel to the board's top edge. Once positioned correctly, the clamps must be tightened firmly to prevent any lateral movement during operation, as a shifting track renders the machine useless. Avjiali Videos Apr 2026
Once the horizontal track is secured, the focus shifts to the installation of the carriage and the vertical arm. The carriage unit, which houses the bearing system, must be carefully slid onto the horizontal track from one end. Users should take care not to force the carriage; if it resists, the set screws on the bearings may require a slight adjustment to looseness before sliding into place. Once the carriage is mounted on the horizontal track, the vertical arm (or column) is typically attached to the carriage or, in some variations, is an integral part of the unit. This vertical arm allows the drawing head to move up and down. It is essential to check that the vertical arm is plumb (perfectly vertical) relative to the horizontal track. Some models feature a tension wire within the vertical arm; this wire must be checked for proper tension to ensure smooth vertical tracking without sagging.

The DP Dual Trac 20 represents a benchmark in the realm of manual drafting equipment, offering engineers and architects a high-degree of accuracy through its parallel motion tracking system. Unlike traditional T-squares, this drafting machine utilizes a rigid rail and a carriage system to ensure that the horizontal blade remains perfectly parallel to the top edge of the drawing board. However, the precision of the instrument is entirely dependent on the care taken during its initial assembly. To ensure optimal performance, the assembly of the Dual Trac 20 must be approached methodically, encompassing the installation of the horizontal track, the mounting of the vertical carriage, and the calibration of the drawing head.
The final and most critical stage is the attachment and calibration of the drawing head. The head is mounted onto the vertical carriage and usually features a protractor mechanism for drawing angles. After attaching the head, the user must verify that the drawing blade is perfectly horizontal. This is achieved by aligning the protractor to the zero-degree index mark and locking it in place. To test the assembly, a test line should be drawn across the paper. The machine is then moved vertically, and a second line is drawn. If the machine is assembled correctly, the lines will be perfectly parallel. If they diverge, the user must return to the horizontal track clamps to adjust the alignment.
In conclusion, assembling the DP Dual Trac 20 is a process that demands patience and attention to detail. The efficacy of the drafting machine lies not just in its mechanical components, but in the rigidity of the track installation and the alignment of the carriage system. By meticulously securing the horizontal rail, ensuring the smooth operation of the vertical arm, and calibrating the drawing head, the user transforms a collection of metal parts into a precision instrument capable of executing complex technical drawings with professional-grade accuracy.
