So, you’re thinking about diving into the world of joinery, huh? A cmt dado stack can be a game-changer for creating strong, clean connections in your woodworking projects. Woodworkers frequently utilize a dado stack from CMT for its precision, and knowing how to choose the right one, use it safely, and keep it in tip-top shape is key. A quality tablesaw paired with the correct cmt dado stack opens up a world of possibilities, from sturdy shelving to beautiful cabinet construction.

Diving Deep: Your CMT Dado Stack Adventure Begins!

Alright, so you’re ready to conquer some serious woodworking projects with a CMT dado stack? Awesome! This guide is designed to be your go-to resource. We’ll break down everything from picking the perfect set to keeping it sharp and humming along. Forget confusing manuals; we’re talking practical, real-world advice you can use right away.

First Things First: What’s a Dado Stack Anyway?

Essentially, a dado stack is a set of saw blades and chippers designed to cut wide, flat-bottomed grooves (dadoes) and rabbets quickly and efficiently. Instead of making multiple passes with a standard blade, you can create the perfect joint in one go. CMT makes some truly fantastic dado stacks, known for their precision and durability.

Choosing Your CMT Dado Stack: Finding the Right Fit

Choosing the right CMT dado stack is crucial. Don’t just grab the first one you see! Here’s what to consider:

• Arbor Size: This is the most important factor. Make sure the arbor hole (the center hole) of the dado stack matches the arbor of your table saw. Most table saws use a 5/8" arbor, but always double-check!

• Maximum Cutting Width: Dado stacks come in various widths, usually expressed as a maximum cutting width (e.g., 3/4", 13/16", 1"). Think about the types of joints you’ll be making most often and choose a stack that can accommodate those widths. It’s better to have a little more capacity than you need, rather than not enough.

• Blade Diameter: Standard sizes are 6" and 8". The 8" blades can cut deeper, which may be important for thicker materials. 6" can be a good option for smaller table saws.

• Number of Chippers: More chippers allow for finer adjustments in width. CMT stacks often include a good assortment of chippers and shims.

• Tooth Grind: Look for a grind that’s appropriate for the materials you’ll be cutting. Flat-top grinds are common for dado blades, as they create a clean, flat bottom.

Here’s a simple table to help you compare:

Feature	Considerations
Arbor Size	MUST match your table saw’s arbor!
Max Cutting Width	Think about your typical joint sizes.
Blade Diameter	Affects cutting depth; 8" is generally more versatile.
Number of Chippers	More chippers = finer width adjustments.
Tooth Grind	Flat-top for clean dado bottoms.

Setting Up Your CMT Dado Stack: Safety First!

Safety is paramount! Before you even think about turning on your table saw, take these precautions:

1. Unplug the Saw: No exceptions! This is the golden rule.
2. Read the Manual: Yes, I know, boring. But seriously, read both your table saw manual and the CMT dado stack instructions.
3. Wear Safety Glasses and Hearing Protection: Always, always, always!
4. Use a Push Stick: Keep your hands away from the blade.
5. Check for Proper Blade Alignment: Make sure the blade is parallel to the miter slot.
6. Double-Check Your Stack Assembly: Ensure all blades and chippers are properly seated and the nut is tightened securely.

Here’s how to assemble a typical CMT dado stack:

1. Start with the outer blade (usually marked "outside" or with a specific tooth configuration).
2. Add chippers as needed to achieve the desired width. The markings on the blades and chippers can help you to know how wide the stack is.
3. Add the inner blade, mirroring the outer blade.
4. Use shims (thin washers) to make very fine adjustments. They typically come in .005" and .010" thicknesses.
5. Tighten the arbor nut securely. Remember to use the appropriate wrench.

Using Your CMT Dado Stack: Making the Perfect Cut

Okay, time to cut! Here are a few tips for getting perfect dadoes and rabbets:

• Test Cuts are Key: Always, always, make a test cut on scrap wood before cutting your project pieces. This lets you fine-tune the width and depth of the cut.
• Feed Rate: Don’t force the wood through the blade. A smooth, steady feed rate will produce the cleanest cuts.
• Support: Use featherboards and outfeed supports to keep the wood stable and prevent kickback.
• Depth of Cut: For deeper dadoes, consider making multiple passes, raising the blade a little higher each time. This reduces strain on the saw and the blade.

Caring for Your CMT Dado Stack: Keeping It Sharp and Happy

A sharp CMT dado stack is a happy CMT dado stack (and a happy woodworker!). Here’s how to keep it in tip-top shape:

• Clean Regularly: After each use, clean the blades and chippers with a blade cleaner to remove resin and pitch.
• Store Properly: Store the stack in its original case or a dedicated blade holder to protect the teeth from damage.
• Sharpen When Needed: When you notice the cuts are getting rough or the saw is struggling to cut, it’s time to sharpen the blades.
  • You can take them to a professional sharpening service.
  • Sharpening at home is possible, but requires specialized equipment and skills. It’s generally best left to the pros.
• Inspect for Damage: Regularly check the blades for chipped teeth, cracks, or other damage. Replace any damaged blades immediately.

So, there you have it! Hopefully, you’re now feeling more confident about choosing, using, and caring for your CMT dado stack. Get out there, start making those perfect dados, and enjoy the process! Happy woodworking!
