I'm very new to table saws, and am having trouble getting a clean cut. The blade cuts fine most of the time, but every once in a while something goes wrong and I'll get a big gouge in the wood.
Here is a picture of what I mean, done on the thinner edge of a 2x4:
I've measured the depth of the gouge, and it's 15 thou. That seems really extreme, especially considering how smooth and perfect the rest of the cut is. This kind of gouge makes fine furniture impossible.
I know the table saw is correctly aligned; that's the first thing I did when I got it. The fence is parallel to the blade, and the arbor has practically no run-out. A splitter was set-up behind the blade, and the blade I used was brand spanking new.
Here's a video of me making the cut shown earlier, so you can see my set-up and feed rate:
Anyways, from what I can tell, the blade vibrated/wobbled a bit and that's what caused the gouge. I could probably reduce the chance of this happening by cutting in several passes, but when I tried that before I still got the occasional gouge. Any ideas on how I can fix this?
