I have an older table saw and I have now had 3 seperate kick backs trying to break down small pieces of plywood.
There is no splitter or riving knife. The fence is generally solid and square, but I believe the first kickback actually threw the fence way out of alignment from the force. Being out of alignment likely made it more prone to kicking back the other two times.
I’m starting to think the cuts I’m making are just a bad idea, even though I see it done all the time.
Assuming the fence is aligned and the blade is square to the table, is this a safe cut to make?
The result from the kickback looks like this:
Scary. It has happened the same way each time. As soon as the blade comes through the back edge, the piece catches, lifts up, lands on the blade (leaving the arc and teeth marks) and throws. Luckily I’m not hurt aside from a couple small bruises and a dent in my car(yikes).
I’m using a “Freud Premier Fusion 1/8 kerf blade
I also think the twist and force on the blade actually caused the teeth the bite into the stainless zero clearance insert. There are no noticable chips in the blade, but the gouge in the insert and the red Freud streaks on insert tell another story. Even though the blade doesn’t look damaged I think I may replace it to be on the safe side.
What else can I do? I spent all of last night re-squaring the fence. I believe this old fence may actually have enough play in it that I need to square and verify after every fence adjustment.
1) I will likely add a splitter.
Would this kind of kickback be prevented with a riving knife? The option I hate, but am considering, is getting a different saw with a guard and riving knife.
Any thoughts or advice would be appreciated.
