Summary:
This video is about how to align a table saw blade. It discusses two methods for measuring blade alignment: using a combination square and using a dial indicator jig. The video also covers how to adjust the blade alignment on both a cabinet saw and a contractor saw.
Here are the key steps on how to align a table saw blade:
Measure the blade run out using a combination square or a dial indicator jig.
If the blade is not aligned, adjust the table or the trunnions (depending on the type of saw) until the blade is parallel to the miter slot.
Once the blade is aligned at 90 degrees, tilt the blade to 45 degrees and measure the run out again.
If the blade is not aligned at 45 degrees, adjust the tilt axis of the blade until the blade is parallel to the miter slot.
Recheck the blade alignment at 90 degrees and make any necessary adjustments.
Here are some additional tips from the video:
It is important to never strive for perfect alignment, as this is not possible.
When adjusting the blade alignment, it is better for the blade to be angled away from the fence, rather than towards it.
After making any adjustments to the blade alignment, be sure to recheck the alignment and make any necessary adjustments.
