Digital Angle Gauge
This tool is 21st-century fun! Yeah, you could adjust your saw's angle using other methods and eventually get it perfect, but this gizmo saves lots of time, and did we mention it was fun? Just crank up your blade, set the magnetic base on the blade and square up the blade to the table (the body of the tool is absolutely square). Then push the zero button to calibrate the device. The Wixey Digital Angle Gauge is available online.
Once it's calibrated, you can adjust the blade to the desired angle, all the while getting an accurate digital readout. When you get the desired angle, whether it's 22-1/2 or 45 degrees, you know it's right on, and you can proceed with your project instead of spinning your wheels micro-adjusting. It's a bit pricey, but we love this device. The Wixey Digital Angle Gauge is available online.
