Bandsaw Blade Wobble - Back and forth?

[Dissolve]

Hello,

After searching the internet for an answer, I just cannot seem to find a solution to this. In operation, my bandsaws blade wobbles back and forth a few mm's which caused the issue of rubbing ion the thrust roller once cutting a piece.

I have spoken to record customer services are ruled out the following;

- New tires
- New blades (Both tuffsaws and record blades)
- Adjusted the tracking
- Adjusted the tension
- Top wheel changed
- New pulley belt

Record have said theres nothing more they can do, so all I can think left might be angle of the lower spindle? I know this is determined by four screws that set and lock the lower wheel spindle into place, does anyone think this might help?

Any suggestions would be great!

Thanks!

Assuming you have checked that the two wheels are co-planar:
Take the blade off and turn the wheels by hand (the top wheel will drop down but that's not a problem)

What is wobbling - the wheel, or the tyre?

If the wheel is wobbling, you may have bearing or spindle damage.

If the tyre is wobbling, change it! Sometimes it has suffered a trauma and no longer sits tightly on the wheel, therefore wriggles about in use. DAMHIKT

Inspect the tyre surface carefully.
Sometimes the crowned surface looks not too bad but has become uneven (due to aforesaid trauma perhaps) which can stop the blade from remaining stable in the middle of the tyre.

Good luck
