Match the tenon to the mating joint
The image lists a 40 mm cutter and 10 mm tenon depth. Measure the mating mortise or shoulder and account for the cutter geometry. Check the 1/2-inch shank against the router collet. Test the joint on matching scrap before routing the finished part.
Before cutting a tenon
- Measure the mating mortise or opening before choosing the bit.
- Compare the 40 mm cutter and 10 mm tenon labels with the joint drawing.
- Check the 1/2-inch shank against the router collet and machine clearance.
- Secure the workpiece and use a shallow test pass to check the shoulder and fit.
- Inspect the test joint before repeating the cut on finished stock.
