With the forward and backwards movement can you see the blade moving forward and backwards on the wheels as it is spinning?

I would think there is no way to adjust the guides with the blade moving forward and backward.

PS
If the blade is moving on the wheel sounds like there is some slop on the upper wheel which means you need to call Grizzly on how to setup your tension system after it comes loose.
Lee I have called Grizzly and got just about no help I am going to order a new blade and see what happens. I that doesn't fix I will have to call Grizzly back and put more pressure on them to help me more.

With the blade moving back and forth you can not adjust the guides. If the blade moves back while running it will cause the teeth to be hit by guides which dull the blade. I would fix the problem before I run a new blade on it.

Lee I called Grizzly back today and got a different person and he wants me to put more tension on the blade. So in the mourning I am going to put the 1/2" blade and run the tension up even higher. I thought I had to much tension on the blade but I will do what he told me. I hope I don't break any thing.

Did Grizzly happen to mention what the 2 nuts locked on the set screws? What do the 2 set screws adjust?

I saw a video and the set screws are for adjusting the horizontal coplanar of the upper wheel.

Hawkeye10,
Did buying the new blade ever fix your issue? I'm going through something very similar to what you described.

Yes did it help some but it still needs improvement. Here is a video showing how to make a jig to check tension. It's not going to cost me anything so I thought I would try it.


PS - I really think the best way to fix it is to buy a 14" Laguna Bandsaw. I had one and should have bought another one.
