This is the content required for an introduction to our routers (handheld or in a router table) - reading this does NOT replace the mandatory session with a tutor! It will make it a lot quicker though ;-)
Please be aware that the CNC router requires an additional introduction.
First off, make sure you have read the tool's manual, if available (it should be linked from its InfoBox).
Safety
a dust mask could be necessary depending on your material
Dangers | Precautions |
---|---|
exposed & rapidly spinning router bit
|
|
the bit can bite into the workpiece and cause kickback if the wrong feed direction or pressure is applied |
|
flying splinters and dust |
|
the bit can get extremely hot
|
when you see smoke, immediately stop and re-think your tool settings - it might be spinning too fast or you could be feeding too slow! Are you sure your bit is sharp? |
no prevention of turning on after loss & restoration of power (keine Anlaufsicherung) | if the power has been lost for whatever reason, make sure the router is turned off before restoring it! |
Feed Direction
The standard direction is the "push" cut, i.e. against the direction the bit would pull the router if you let go. In short, you need to move the router counter-clockwise around the outside of a workpiece and clockwise for inside work (holes, recesses). It is probably more clear after watching this video tutorial!
As mentioned in the video as well, there are only a few situations where you might want to try a "climb" cut once you are sufficiently experienced with this tool. When you do attempt climb cuts, be aware that it can cause kickback to the router and the workpiece! Only take shallow passes to maintain control.
Feedrate
The proper combination of rotation speed and tool advancement is determined by your bit and material.
- be cautions not to remove too much material at a time - several passes are usually necessary if you want to go deep
- going too slow can cause the wood to burn, going to fast can cause the wood to splinter and even damage the bit
Demonstration
The tutor will show you these steps in detail:
- inserting a bit
- unplug the router
- choose the proper collet that matches the bit's shaft diameter (6 or 8 mm)
- insert at least 20 mm of the bit's shaft
- check proper fit and balance before turning the motor on
- never tighten the collet without a bit inserted!
Suggested Reading
For tips and tricks read the book "Woodworking with the Router" (available at the space). Tips for choosing the proper feed direction can be found on page 37ff.
Router Table
When working on a router table, additional care needs to be taken as the router is turned upside down in a fixed position!
- the workpiece can be grabbed and shot across the room if you attempt a climb cut, only do push cuts!
- only feed from right to left when you work in front of the bit!
- see schematic for other cases, but make sure you really understand what's going on
- clamp the router table to a workbench before turning it on
- keep all body parts at least a hand's width away from the exposed bit (use push blocks if that's not possible)
- use all possible fences, guards, featherboards etc. to secure the workpiece and reduce exposure of the bit
- make use of a starting pin (or similar) when working fenceless with a bearing bit tip #6
Waiting List
This introduction takes longer than many others and usually can't be done spontaneously during regular opening times. If you would like to receive it, please add yourself to >> this list << and we will find a good time once a few members are on it!
