Grade 8 - Overlapping and joining of members

The general rule in this section:-

"Two pieces which are running in the same direction (and this includes spacers) may not be gluedtogether for a distance longer than 10 mm at any one spot.

It is also no permitted to lay two pieces directly alongside each other (face toface) and merely glue them at points along their length. In this latter case spacers must be used."

Two parallel members may not be glued together along their length. They may however be joined together via intermittent spacers but each spacer may not be longer that 10 mm, and the spacing between the spacers should be more than 50 mm
