Nutcracker MasterClass - Cutting a Jaw Slot on the Table Saw
Cutting the jaw opening on a handcrafted nutcracker is easily one of the trickiest parts of the entire build. Because it requires a partial, stopped cut on a cylindrical torso, safety and precision are paramount. In his Nutcracker Masterclass, instructor Paul Anderson walks through how to safely execute this critical step on the table saw using a custom jig.
Core Safety Rules
- Keep Hands Clear: Never place your hands near the blade. Always hold the workpiece using the rear handle of the fixture well away from the cutting zone.
- Maintain Dual-Point Contact: Keep the fixture flat against the saw table and flush against the fence at all times.
- Pre-Plan the Saw Shutdown: You must turn off the saw mid-cut while holding the jig steady. Use a knee switch if your saw has one, or enlist a helper to hit the off button once you reach your stop mark.
- Blade Selection & Setup: Use a standard 10” table saw with a sharp, full-kerf (thick rim) blade rather than a thin-kerf blade to minimize flex and ensure smooth cuts. Fully raise the blade height to maximize the curve geometry.
Step-by-Step Cutting Process
- Mount the Torso Upside Down & Backwards: Identify the front of your sanded torso, then mount it in the fixture facing the rear handle. Because of the blade’s arc, inserting it backwards ensures the deepest entry cut is where you need it most.
- Align for Parallelism: Ensure the marked reference lines on top of the nutcracker are parallel with the fixture opening. Secure the torso using 1/2” cabinet screws.
- Mark the Stop Point: Measure down 2-1/2” on the interior reference area to mark where the blade should exit—this is your signal to shut down the saw.
- Make the Initial Cut & Lock the Stop Block: Pass the jig through until the blade reaches your reference mark, hit the power stop, and wait for the blade to come to a complete halt. Slide your fence stop block flush against the jig and lock it in place.
- Clear Material & Verify Center: Nibble away the remaining interior waste with subsequent passes. Periodically check the fit using the actual jaw piece, and use calipers on the exterior high points to ensure equal distance on both sides.
Pro Tip on Grain & Fitting
Leave the cuts just shy of your final line to prevent chip-out on the visible front grain. You can easily make up for minor discrepancies by fine-tuning the jaw piece itself during final assembly.
