A while back the blade on my Laguna 14/12 started minor but rapid trackings back and forth on the top wheel (seen through the window). I tried several adjustments and none worked. Then during light work (not resawing) the tracking got progressively worse to the point the front of the blade was moving halfway out the cool blocks and rocking the whole bandsaw in it’s base.
I called it quits and set up for a blade change. When I pulled the old blade out, it already had a kink. When I went to coil it, the blade broke appart in my hands..
The 115″ blade was a 3/4″ premium carbide tip made by Diamond Saw Works and bought through Highland Woodworking. I had the tension set right on the line between 1/2 and 3/4. I’m replacing it with the very same blade and wondering if this a one-off, or did I have the tension too tight? Anyone else have these blades break on them?

You can’t really tension them too tight. I noticed that when a blade starts wobbling back and forth, the wobbling increases with time and I replace it when it becomes unbearable. If it did that from the start, my guess is that the blade was not straight at the weld.

I went through a few Lenox carbide tipped blades on my 14/12, and they were a major fail. The 3/4" Laguna Resaw King carbide tipped did the job perfectly.
The Resaw King lasted longer, but the 1/2" Highland Woodslicer did just as good a job on resaws as the bigger carbide blade.
It's my opinion that the 14/12 is just a little too small and underpowered for a 3/4" blade. But the thinner blade on the Resaw King is your better bet if you really want to stick with carbide.
