Fence Adjustment Calculator
Cut a test strip, measure the error, and get the exact fence correction. Lock it in and stop “sneaking up” on final width.
Fast calibration routine
- Set fence to a target (ex: 3.000").
- Rip a test piece from stable stock.
- Measure actual width with calipers.
- Enter target vs actual, apply offset.
Tip: Do this after blade changes, fence bumps, or seasonal shop swings.
Fence Adjustment Calculator
Enter values to compute fence offset.
How to use
- Enter your intended (target) rip width.
- Enter the measured actual width from your test cut.
- Apply the suggested correction to your fence scale/setting.
Pro tips
- • Use the same measuring tool every time (calipers beat tape for this).
- • Test with the blade height and feed rate you normally use.
- • If the error changes with position, your fence might not be parallel.
FAQs
Why is my fence scale off even if the fence is parallel?
The cursor (indicator) can drift, the blade kerf may differ from assumptions, or the tape scale can shift slightly. This calculator gives a direct correction from real output.
What if my results vary cut-to-cut?
Check stock flatness, fence pressure consistency, blade sharpness, and feed technique. Make three test cuts and average the measured widths.
Should I calibrate for every blade?
If your blades have different kerf or you swap often, yes. Even small kerf differences can show up as repeatable width error.
