Router lift setup: zeroing bit height and reading the dial
A router lift only pays off once it is set up right. Here is how to zero the height gauge, read the dial accurately and get repeatable bit changes.
By SQUAREFORGE Shop Desk · Updated
Key takeaways
- Zero the height dial against the table surface, not against the insert plate alone.
- A through-table crank means no reaching under the table for every height change.
- Recheck zero after swapping insert plates or router bases.
Zeroing the height dial
- Install the insert plate flushUse the leveling screws so the plate sits flush with the table surface, front and back.
- Bring the bit to the table surfaceCrank the lift up until a straightedge across the table just touches the top of an unspinning bit.
- Zero the dial at that pointSet the dial or digital readout to zero here, since this is your true table-surface reference.
Reading the dial accurately
| Dial type | Typical resolution | Best for |
|---|---|---|
| Analog ring dial | 1/64 in. per mark | Quick, repeatable production cuts |
| Digital readout | 0.001 in. | Fine joinery and inlay depth |
Keeping it repeatable
- Rezero any time you swap between router bases or insert plates.
- Keep the lift's threads clean and lightly waxed so it turns without binding.
- Write down common bit heights for repeat setups like drawer-bottom grooves.
Router table setup checklist
| Frequency | Tasks |
|---|---|
| Before each session | Check insert plate flushness, confirm bit height on scrap |
| Between bits | Rezero height gauge, check collet for debris |
| Monthly | Clean and wax the table surface, inspect featherboard fingers |
/ Frequently asked
Do I need a router lift if I already have a router table?+
A lift adds above-table height adjustment and bit changes, which saves time on jobs with many depth changes, but a fixed base still works for simple setups.
How often should I check insert plate flushness?+
Check any time you swap plates or after moving the table, since a plate high or low by even a hair changes edge-routing results.
