This page is INCOMPLETE and still missing some important information before it can be used as a resource. Please use the "Discussion" feature above or talk to one of the tutors if you would like to help improve it. Thanks!



helpful links besides the manual:



This is the content required for an introduction to our jointer-planer combination machine - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)

Let's begin! First off, make sure you have read the machine's manual (felder-gruppe.at (DE), (EN))

This is one of those machines that can cause very serious injuries when something goes wrong, so do not use if you are alone in the Space'.

Safety

Personal protection: Protection - no gloves.svg Protection - goggles.svg Protection - hearing.svg

Dangers Precautions
Danger - draw-in.svg
radidly revolving knives - exposed at the top (jointer): draw-in and cutting danger
  • use the blade guard to only expose as much of the blade as needed
    • never remove the blade guard!
  • keep your fingers together when you guide the workpiece, do not spread them (nicht die Finger abspreizen)
  • the hand at the back of the workpiece is especially in danger of touching the knives
    • never hold the workpiece from behind - keep your hands on top and a hand's width away from the edges
    • use a proper push block whenever possible
  • pieces that are narrow and flat may only be jointed with the help of a secondary fence your fingers can glide over [1]
kickback: the jointer may grab the workpiece and throw it back to the infeed side
  • inspect your workpiece for difficult areas in advance, knots are tricky enough but loose knots need to be removed!
  • start with a low cutting depth - only very soft woods with an even grain can be jointed with several mm at once, rather take many shallow passes!
  • stand next to the machine where you can comfortably put downward pressure on the outfeed side without walking during the pass
  • push blocks for the jointer require a "lip" that grabs the end of the board - friction-pushing on top is not sufficient

Suggested Reading

Besides these safety notes, you should read <...>

Demonstration

The tutor will show you these steps in detail:

  • how to use the blade guard (Schutzbrücke) on the jointer DE video
    • to joint the board's wide faces: covering the entire blade, raised just enough for the board to fit under it
    • to joint a board's narrow sides: lowered all the way, moved from the fence just enough for the board to fit between
  • how to read the wood grain for the proper feed direction
  • setting the cutting depth
  • <...>
