Here’s the story. I’ve been watching the Woodworking Online videos. The one on dadoes was kind of fun. They suggested making zero clearance inserts for various sized dado stacks. Here’s what I did:
Sorry for the blurry pic.
Here's the back:
I made this out of some dimensional oak that was fit with my stationary sander and some tape on one end to get the friction fit nice and tight.
I clamped the insert into the saw and began to raise the blade. I did this very slowly. What ended up happening is that the dado stack burned through the insert rather than cutting through it. I ended up with this:
Lots of gunk on the teeth and a missing tooth on a chipper! To be honest I had just used this stack to cut some lap joints on some scrap 2x4s for a tool cart so I don't know if that operation broke the tooth or if it was the burn through the insert.
So, what did I do wrong? I think I might have gone too slow on the blade height. Would I have been better off going a little faster in order to try and get chips and not burn? And, is that blade shot or can I clean off the teeth and just move on? I'm pretty sure I don't want to use the broken chipper but I'm still on the fence about that one.
The dado stack is less than a week old. It's a Grizzly 8" that was just replaced by Grizzly becuase of other broken teeth after I had a plastic push stick contact the blade - yes it was a stupid mistake/accident on my part that taught me a lot. The thing is, at $50 it seems like a bargen, and I really, really want this setup to work. The cuts could be smoother but I'm willing to live with it if the thing would just stay together.
