Making things that fit togetherLesson 2 of 16
Finger joints
Turn a panel edge into teeth so two parts lock together.
Start with the panel and the edge that has to join something.
That edge becomes a row of teeth, sized to the material you are cutting.
Cut a matching pair and they slide together and stay square.
Every setting
12What each number in the dialog means, and where it starts.
Panel width in millimetres
Panel height in millimetres
Which edge gets the teeth
Fingers stick out, slots cut in. Mating edges take opposite roles
Finger size in millimetres
Material thickness in millimetres (tooth depth)
Positive loosens, 0 is zero clearance, negative presses.
Beam width. Fingers grow a kerf, slots shrink one.
Swell each tooth flank so the joint grips. One half of a pair only.
Light comes apart again. Firm goes together once.
