Making things that fit togetherLesson 3 of 16
Press-fit slot
Cut a slot another panel presses into and stays in.
Start with the panel and the piece that has to go into it.
The slot is cut a touch narrower than the piece, to allow for what the beam takes away.
The piece pushes in snug and holds without glue.
Every setting
10What each number in the dialog means, and where it starts.
Slot length in millimetres
Slot width in millimetres: material thickness minus kerf
How many slots in the row
Spacing between slots in millimetres
Swell the slot walls so the panel is squeezed, not just held
Material thickness in millimetres. The bumps are sized from this.
Beam width (mm). A bump under half of one is burnt away.
Light comes apart again. Firm goes together once.
Row left edge (mm)
Slot top edge (mm)
What it is
A slot sized to the material so another panel presses straight in. Set the width to the thickness minus the kerf; a scrap edge should push in snug.
