Rostock MAX v2 Assembly Guide – 4thEd.
There are two holes on each end of the vertical supports
that can take the retaining screws we're cutting threads for. The
holes you need to use are the “top” ones.
Write “top” on each vertical support plate in the location
shown in the figure below and then carefully drive the #10-32
socket head cap screw through the holes closest to the “top”.
Drive the screw though completely and then remove. it.
Repeat this for the other two vertical support plates.
