How to Test the Accuracy of the Best Combination Square for Woodworking

Before using the best combination square for woodworking, make sure you’re holding an accurate piece. A little mistake can affect the whole outcome of your project. To ensure flawless results, simply do the following:

  1. Tape a piece of white paper on a perfectly straight board.
  2. Put the square’s anvil against a straight edge.
  3. Draw a straight line along the outer edge of the blade.
  4. Flip the combination square.
  5. Draw another straight line that’s only 1/32 inch away from the previous line.
  6. Gauge the shoulder’s angle with the blade by doing it against a 45-degree drafting triangle.

If the two lines are parallel to one another and the square’s angle matches the triangle, the tool is accurate. On the other hand, if it isn’t, contact the seller to fix the problem.

How to Choose the Right Combination Square for Your Budget

Do you prefer a cheaper combination square? What about a more expensive one with top-notch features? Whether you want a pricier or a more affordable square, you should know what exactly to look for.

Check out the following tips for different types of buyers:

  • For freelance construction workers and DIY enthusiasts: Opt for a practical option made of die-cast zinc or aluminum. It can last for years with careful use. Meanwhile, if it gets broken due to high drops and other harsh situations, you wouldn’t be so disappointed because of its cheap price.
  • For buyers ready to spend a bit more money for better quality: Choose something made in India or China, great manufacturers of affordable yet quality tools. You may even pick a set with different sizes or tools so you can build more stuff. Regarding the material, look for squares with satin or polished chrome blades and cast iron heads.
  • For people all set to buy the best no matter the price: Look for combination squares that are also designed for metalworking. You may resort to the cast iron kind, but you should also consider buying a square with a head made of forged steel, hardened to perfection.

Here are more factors to think about when you prefer costlier combination squares:

  • Check if the combination square has a center head. That component is specifically a casting with a distinct “V” shape. Its purpose is to find the center of a turned blank or a big dowel.
  • The protractor head should have graduation from zero to 180 degrees etched by a laser to keep the markings permanent. Avoid the ones with burrs.
  • The blade should be a little bit thicker than the standard. You can easily make sure of this by checking if it’s harder or stiffer. When it comes to the graduations, they should have darker markings for a more defined look, typically made possible by acid etching.
  • If you’re usually working in bright environments, choose a square with a matte finish. Polished chrome will only reflect glare.
  • Buy a combination square with a 4R graduation for a more successful woodworking project. This type of graduation has separate sides for 8ths/16ths and 32nds/64ths.
