I suspect that this has already been answered. Years back in a high school wood class I was taught to keep the table saw blade all the way up. This is to reduce kick back as the blade is pushing the stock down against the table. The other school of thought is to keep the blade as low as possible for safety. I use both, but prefer the blade all the way up. This seems to make it easier to feed the stock though the blade. I would like to read some feedback on this topic.

I was always taught that the blade should be just high enough so that the gullets clear the top of the workpiece.

I raise the blade like Charlie, just high enough so the gullets clear.

Same here. I go about 1/4” higher than needed to clear the gullets.

How about a fourth vote for raising it until the gullet clears. This lessens the potential for injury should your hand or other body part come in contact with the blade.

Other reason to keep that saw blade as close as possible to the wood height is that I’ve found that I get a cleaner edge that way. I use a saw on a rail rather than a table saw, but I believe the physics are the same for the tablesaw.

And my only personal kickback experience has been with a router table, but I’d guess that if the piece starts to bind between the blade and the fence, it’s probably as likely to ride up to where there’s real kinetic energy in the blade as it is to be pulled down by the higher blade. So I’d go as low as possible.

I’m about with Patron, I raise mine the height of the tooth over the wood. It seems like I have less dust on the tabletop that way and also as he mentioned less blade exposure to your fingers and hands.

Make that a +2 on the 1/8th – Cleaner cuts….less stress on the wood….and keeps the piece more firmly on the table…

1 tooth over the board, safer, better dust control, better cut quality

Yeap, there are two schools and never ending debate…

I love “high blade” for solid wood and low blade for man made sheet goods…

The high blade is less prone to overheat and distort i.e. – runs cooler and it’s easier on the motor, i.e. faster feed rate and less burn marks…

I think that every one that recommends the “Low blade for safety”, doesn’t use blade guard and/or his fingers are too close to the blade during the cut…

Usually, the critical point that the operator can cut his fingers due to high blade is the end of the cut so, if one sets the blade to 2¼” (to cut a 2” thick material), at the end of the cut, 2¼” of a “naked blade” will be exposed and wait to cut your fingers unless, your fingers are not there (long push stick) and/or the blade guard is installed…

Please have a look at the pics below…who can “catch” me….

As you can see, no fingers around – no “food for the blade”...

i agree with most…gullet bottoms at the top of the wood
