Table Saw Alignment??

[MrChips]

When ripping a board say about 2' long, about the last 6" or so is burnt by the saw blade. And you can hear additional noise.

What is causing the problem. Using a 12" 80 tooth carbide blade.

check if your splitter is in line with the blade using a straight edge and align as necessary...it could be out and when your timber goes past it it pushes the timber back onto the blade

Some other possibilities to answer your burning question…

The fence may not be properly aligned parallel to the blade...

An 80 tooth blade is usually designed for cross cutting not ripping so either use a blade with fewer teeth – say 30 – or feed the material more slowly...

Check alignment of the riving knife (splitter)

Hope this helps

Sounds like you may be getting re-cut from the back of the blade.
Check your blade alignment. Align it parallel to the mitre slot. Then check the fence is also aligned parallel to the mitre slot.
Check the riving knife/splitter is centralised with the blade.
Check your feed rate, not too fast with an 80 tooth blade

Mark one tooth at the front of the blade with a felt tip pen. Use a combination square as a depth gauge from the mitre slot to the marked tooth. Lock off the combination square. Rotate the blade half a turn so the marked tooth is at the back of the blade. Using the combination square, check that the marked tooth is the same distance from the mitre slot as the front measurement. Adjust as required.

I would check for a warp in the fence, or a gentle curve over the length of the fence that causes the fence at 1'6" past the blade to be closer to the blade than the fence at the point it passes the blade, this would push the wood out of square with the blade. Curved wood will also cause this.
If not then I would go through the list above

Thanks for all these good tips.
