Synonyms: planer-thicknesser, power jointer, thickness planer;
DE: Abricht- und Dickenhobelmaschine, "Abrichte", "Dickte"
Material: naturally structured wood
(not more engineered than glued laminated timber!)
Location: CNC Area
Status: in commissioning
Manual: (DE), (EN)
Similar (More or Less): jointer plane, planer

A jointer is used for straightening the narrow sides of wooden boards which is necessary for panel glue-ups and some kinds of joinery. It basically consists of a flat surface with a slightly protruding cutting drum at the center.

We chose to get a combination jointer/planer to save valuable space: thanks to the second flat surface under this cutting drum, you can also thickness boards with this machine! You can therefore buy rough-sawn wood and dimension it at the CoMakingSpace.

This tool is not ready for usage yet, since not all commissioning steps are completed yet. The process is not yet tracked on GitHub. Feel free to contribute to making it usable, any help is very welcome!

when moving a workpiece over the jointer, your fingers should always remain close together and far from the blades

Jointing (using the top table of the machine) creates flat, perpendicular surfaces. Flawless edges are especially important for glue-ups, e.g. to make your own glued laminated timber panels!

You should check the fence for squareness against the table, e.g. with a square or inclinometer. Advanced users may also try to joint at other angles than 90°.

If you flip the top of the machine back, you're able to feed a workpiece under the knives to plane its top surface. Thereby you can obtain a board with parallel faces and dial in its thickness exactly as you want. Make sure you fully understand grain direction or you'll easily get tearout!

Feeding boards through at a slight angle may help to avoid "snipe" (Hobelschläge) but you should be prepared to cut off unsightly ends afterwards - i.e., plane oversized boards and cut them to length as the next step.


Dust Evacuation

The planer should only be used in tandem with a suitable dust evacuation system. The intended machine for this purpose is the Felder AF 14, that should be in close proximity to the planer. The system should be hooked up through the automated switch box (switched output) mounted on the metal frame, that should also be connected to the planer (trigger output). Once the planer is started the vacuum system will turn on after 3 seconds and turn off once the planer is off for 8 seconds. Make sure to set the switch on the vacuum motor to '1' (ON) before starting!
