Installation & Setup

This guide covers the installation and modification of the ZC-10 Zero Clearance Insert for Harvey Alpha table saws. A zero clearance insert helps reduce tear-out, provides support for the material being cut, and minimizes the gap around the saw blade. Ensure you are familiar with your saw's operating procedures before proceeding.

⚠ Table Saw Safety

Disconnect power before installing, adjusting, or removing blades or inserts. Never modify the insert while the saw is connected to power.

Always wear safety glasses and a dust mask or respirator. Cutting aluminum produces fine chips and debris.

Use push sticks or push blocks when cutting small pieces to keep hands away from the blade. Ensure blade guards are in place and functioning during normal operation.

Wear fitted clothing — avoid loose clothing or dangling jewelry that could get caught in the saw.

Read the instruction manual for your specific table saw model before proceeding. Familiarize yourself with all safety features and operational guidelines.

Tools Needed

Carbide-tipped blade suitable for cutting aluminum

Adjustable wrench or pliers for adjusting the rear bolt/nut

Hex wrench set for adjusting bolts and levelers

Installation & Cutting Procedure

Prepare the Insert

Place the ZC-10 insert into the saw's throat plate area. Ensure it is oriented correctly with the back-end hook and front screws aligned with the corresponding holes or slots on the saw table.

Important — Remove the Riving Knife First

The riving knife extends over the blade and will prevent the blade from cutting completely through the insert. Remove the riving knife before cutting the ZC-10 slot. It can be reinstalled after the slot is cut.

Secure the Insert

Screw the insert into place, starting with the back-end screw to hook it securely. Fasten the front screw next, ensuring the insert is level with the table saw surface. Use a small level to verify.

Adjust the Saw for the Insert

If using a more powerful model such as the 4HP HW110S, you may need to extend the front, back, and leveler bolts to raise the ZC-10 above the blade height to accommodate the higher blade setting.

Cut the Zero Clearance Slot

With the insert secured and leveled, turn on the saw. Slowly raise the blade while the saw is running — start at a lower height and gradually increase, allowing the carbide-tipped blade to shave through the softer aluminum. Continue until the blade reaches its full height or the desired slot size is achieved.

Final Adjustments

Turn off the saw and let the blade come to a complete stop. Check the insert for any burrs or rough edges on the aluminum and smooth if necessary. Re-check the level and security of the insert to ensure it remains flush and stable.
