GET THE BEST TUNING FROM A BANDSAW 'Alex Snodgrass of Carter Industries has an excellent video
https://www.youtube.com/watch?v=wGbZqWac0jU on a tune up method that works well.
Tuning is only that and nothing else. If you really want to get the very best use of your bandsaw on an ongoing basis, then the Steve Maskery DVD's will show you far more and they are a real investment that you should own.

Carter blade guide video with Alex Snodgrass.
This shows how well they work for smaller blades with a guide only above the table and I have one of these which works well. The back of the blade gullet is also on the centre line on the upper wheel as per his usual advice.

TUNE WITH SOUND ?

Whenever you have put a blade on a bandsaw, ask yourself the following questions:-
....... are you managing to get the that smaller blade running freely and central on the top wheel ( without guides or rear bearing near the blade ) with the gullet of the teeth in the centre of the top wheel. That's the first priority before closing in guides and bearings. ???
Once the guides and bearings have been brought to the correct position, is the blade remaining where it should be when run under power and switched on and off several times ??
Is the blade running vertical 90° to the table alignment, front and back and side to side?
Are you sure that the tension is correct, or as near as it can be. Each blade is different, so needs to be checked whenever changing blades.
If all these things are correct, then you should get a true cut unless you are trying to cut the wood too fast and it's filling the teeth with sawdust and pushing the blade out of line.
Have you checked the blade to see if teeth are damaged in any way.
