Description
Lap joints on beam constructions are often used to support load transfer and facilitate the support structure's assembly.
In this example, the HK 85 is used in conjunction with the adjustable groove cutter to cut the posts to size and to produce the lap joint out of the posts.
Material list
- 16 x 16 cm posts
- 8 x 16 cm joists for the double beams
Tools/accessories
Alternative tools
Preparation/set-up
-
Pull the post ends apart. The depth of the lap joint in this example is 25 mm. The post end's section should be below the upper edge of the beams (here -0.5 cm) due to possible wood shrinkage.
Procedure
-
Cut off the post ends using the cross cutting guide rail and the HK 85. The cross-cutting must be carried out in two steps.
-
Turn the post over and make a second cut. With the cross cutting guide rail you can achieve a very good result quickly, even when cutting thicker woods.
-
Marking a hole
A hole (14 mm) for a bolt connection should be made for this connection.
