Bandsaw drift and fishtailing
I have a Carbatec 14" bandsaw (25 yo) and had it set up very nicely ie straight and smooth cuts. I changed the blade to a 13mm 6 tpi (band new, straight out of the packing) and I now experience drift and rough cuts. I have made all the adjustments as best I can - any suggestions how I can remove the drift - I don't want to have to make jigs etc to compensate, and to get a smooth cut?Many thanks,KenM

Follow the Snodgrass setup and you cant go far wrong.

Those results are pretty classic for "not enough tension on the blade"

agree with China,
is your new blade wider than the old blade? if so your machine might not be able to obtain the correct tension for the blade width.

You should be able to get enough tension on a 13mm blade with a 14" bandsaw, which should solve the fishtailing.
With regards to the drift as others have said, if previous blades have worked well and it is tracking properly the fault maybe with the blade.

I agree tension is probably the cause. Next most common reason is most folks don't realise how close to the middle of the wheels the teeth have to be. This is all explained by the Snodgrass setup method provided by oraloon, after that I'd suspect the blade.

Ken, if there was no drift with the previous blade, it suggests that the new blade is different. Perhaps it has more set on one side. If so, run it against a diamond stone to smooth away the excess set.
There may not be enough tension in the blade (which requires more if wider than the previous blade).
The guides may not be providing equal support.
Pushing the blade to hard (fast) will cause the gullets to load up, and this will drive it off course.
Too many teeth (e.g. 6 vs 3 tpi) will also cause the teeth to load up too quickly. I never use more than 3 tpi on a blade this size. Indeed, my 1” resaw blade is 1.3 tpi.

Its is also possible that you old blade was a hard-back blade like this https://www.lenoxtools.com/Pages/Pro...d_NeoType.aspx, and your new blade is a flex-back like this https://www.lenoxtools.com/Pages/Pro...FlexBlack.aspx or vice versa.
They do differ a little in setup
izzy swan has a video on the difference in setup, and why https://www.youtube.com/watch?v=cOJsMOurR68
