(Limited usage; Location of the holes!)
The making of the basic construction - the frame - must be done very accurate: Head and side parts have to be assembled on a plain surface, in order that the frame becomes straight.
The plank for the track must be mounted absolutely plain, to get the ideal position of the track. The plank must be reinforced with a beam to prevent long term distortion. The frame gets additional strength by transversal ribs.
During the work with the wooden parts you should consider the cables to install and should see to the necessary openings. Also, space and openings for the junction's mechanism should be left free by now.
It is also recommendable to see to the fitting of the legs by now. There must be enough space provided for the connecting bolts at the ends of the module.
High quality ply wood or cross-banded lumber veneered board (CLV), not below 10 mm thickness, is suitable for the building material. Beyond repair is chipboard and suchlike.
After the assembling all wooden parts should be painted inside and outside, to protect the wood from getting wet (and by this from distortion).
It is recommended to use the color light gray (RAL 703x) or nut (RAL 8011) for the outside of the frame. A light colored inside helps during an error detection if the module is already placed in a layout, because cables and parts of the mechanic are better visible.
The boreholes for the bolts and openings for cables at the profiles should be installed not until the tracks are mounted, because they fit better that way. There are two holes with 8 mm diameter to drill, 58 mm below the rail's head, 120 mm right and left of the middle of the track.
Also, openings for cables to the next module should be installed as shown in the drawings.
Sometimes it is necessary to connect modules by c-clamps. Therefore, no beams, brackets or suchlike should be installed inside near the ends of the module, which would block the installation of a c-clamp.
