Step 3
Insert the bush into the recess in the router base and secure it in place with the locking ring.
The Offset
When using a router bush, there will always be an ‘offset’, which is the distance from edge of the cutter to the outside (or bearing) edge of the bush. For example, when a 20mm bush is used with a 10mm cutter, the offset is 5mm (20-10÷2). The dimensions given for each bush on the inside of the box lid also allow you to calculate the offset with different cutters, as seen from the chart.
| Bush diameter | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| 10 | 12 | 14 | 16 | 18 | 20 | 24 | 30 | ||
| Router | |||||||||
| 6 | 2 | 3 | 4 | 5 | 6 | 7 | 9 | 12 | |
| 8 | – | 2 | 3 | 4 | 5 | 6 | 8 | 11 | |
| 10 | – | – | 2 | 3 | 4 | 5 | 7 | 10 | |
| 12 | – | – | – | 2 | 3 | 4 | 6 | 9 | |
In conclusion, changing the offset by using a different cutter/bush combination expands the versatility of the router and enables it to be used in a variety of unique ways.
