Jointer-Planer Introduction: Difference between revisions

Revision as of 10:56, 10 September 2020

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!

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 for usage in jointer and planer mode

Personal protection:

Dangers	Precautions
Risk of serious injury	This is a dangerous machine with a risk of serious injury. NEVER use this machine when you are alone in the space!
radidly revolving knives	you MUST NOT wear gloves, loose clothes, dangling jewellery or open long hair

Additional Security when using as a jointer

Dangers	Precautions
radidly revolving knives - exposed at the top: draw-in and cutting danger	you MUST use the blade guard - only expose as much of the blade as needed you MUST use push blocks on any workpiece that is not large enough for your to hold down with your hands without any part of your hand overhanging the workpiece you SHOULD use push blocks - ONLY IF you are unable to use a push block: you are risking your fingers being pulled into the rotating blades and dismembering them you MUST keep your hands flat and fingers together you MUST keep your hands ON the workpiece - NEVER hold or push the workpiece from the sides
kickback: the jointer may grab the workpiece and throw it back to the infeed side	you MUST stand firmly on the long side of the machine, downward pressure on the outfeed table side, and without walking during operation you MUST ensure that the infeed side is clear you MUST stop immediately if other people step into the infeed area you MUST inspect your workpiece for difficult areas in advance, knots are tricky enough but loose knots need to be removed! you MUST use a low cutting depth and increase to higher cutting depths ONLY for softer woods

Additional Security when using as a planer

Dangers	Precautions
radidly revolving knives	you MUST NOT put your hands near the top planer housing during operation
kickback: the transport mechanism may fail and throw it out side	TODO: Can this happen?

Demonstration

The tutor will show you these steps in detail.

Basic Usage as jointer

How to prepare the machine, if it's currently in planer mode - manual: 8.8
how to read the wood grain for the proper feed direction
adjusting the jointer chipload (Spanabnahme) - manual: 8.2
adjusting the jointer fence - manual: 8.4
adjusting the jointer blade guard (Brückenschutz/Schutzbrücke) and moving the workpiece to...^{DE video}
- joint the board's wide face (Abrichten) - manual: 9.4.4 & 9.4.5
  - the guard covers the entire blade, raised just enough for the board to fit under it
- joint the board's narrow edge (Fügen) - manual: 9.4.6
  - the guard is lowered all the way and moved from the fence just enough for the board to fit between

Advanced Usage / topics

adjusting the jointer Fuge - manual: 8.3
- rarely needed! return to original (described) setting if altered?
- a very slight Hohlfuge is desirable for many glue-ups: you'll need fewer clamps and the ends of your boards will always connect in a panel^[1]
- to test the result: let two jointed boards face each other - you will thus amplify the extent of curve (x2) to make it more visible^[2]

Usage as planer

How to prepare the machine, if it's currently in jointer mode - manual: 8.7
adjusting the planer thickness - manual: 8.5
feeding a workpiece through the planer
switching from planer to jointer
