I have been working this week on setting up my first bandsaw. Its a 14” cast iron Craftsman Professional model 22424 I got cheap on Craigslist. From everything I can tell it is identical to all the other import 14” bandsaws. The saw came with a 1/4” blade. It came with the Kreg bandsaw fence. I tore the whole thing apart to clean it and inspect it and took the opportunity to replace all the bearings. I also replaced the spring with a Carter Products high tension spring, since the original was slightly bent. Per suggestions on here, I watched the Alex Snodgrass bandsaw clinic video and attempted to setup the saw per his instructions. I squared the table and fence to the blade and tried making some cuts. I get between 4-5 degrees of drift. I then tried centering the blade on the wheel like the instruction manual says instead of centering the gullet like Snoddgrass says and I get about the same amount of drift. What could I be doing wrong? Is it maybe my blade? Should I ignore his instructions and co-planer the wheels? Any help would be appreicated.

These are pretty elementary points, but:

a. Are your guide blocks properly adjusted?
b. Are you cutting with the minimum necessary amount of exposed blade?
c. Are you forcing the cut? Pushing too hard against a not-so-sharp blade could be the problem.

Am by far no expert but will tell you that I had initially experienced drift using a 1/4” blade and after switching to a 1/2” 3tpi blade for resawing had absolutely no issues what so ever. My guess is to try a larger newer blade anytime sharp curves are unnecessary.

A. As far as I know. I installed Coolblocks and new thrust bearings. Everything is as close as possible without touching.
B. Yes. Only about 1/8 above a 4/4 piece of pine.
C. This was maybe my guess. It seems like I have to push harder than I would’ve expected to cut, but I haven’t touched a bandsaw since high school 15 years ago.

I think maybe I’ll stop at the hardware store tonight and pick up a new blade.

is the blade installed with the teeth pointing down?

I’m not going to say why I thought to check that….

My guess is your blade is dull. Put a new one in and see if there is a difference.

New blade, and buy a 1/2” 3tpi blade made for resawing. A 1/4” blade won’t do well with straight cuts.

I love the Snodgrass method has been working awesome for me for the last few months like the others said try a new blade.

The blade must be dead center on the tires.

You’ve got a blade problem.
Correct tension, guides set, saw away.
I use some of the Snodgrass suggestions, but my Grizz works best with the blade, not the gullet, centered on the tire.
Just my results on a Grizz 0555LX 14” (no riser) with an aftermarket blade.

Would a 3/8” be a good general blade? I plan to get a 1/2” when I need to do resawing, but I think my normal use will be crosscutting and cutting gradual curves in 4/4 hardwood and maybe a little plywood.

+1 for getting a good blade, I like the Timberwolf ones, doubt you’ll find them in most stores. Woodworker’s supply always seems to have good prices on them, average blades run from 12 to 20 bucks so don’t be afraid to get a few widths, there isn’t really a combo blade for the band saw, you’ll need different widths and TPI for what you plan to be cutting.

Not according to Alex Snodgrass’s setup, which I have had fantastic luck with on my humble bandsaw.

If it’s not how you position the blade, then the problem is your band saw blade.

Personally, I have a 1/4” and a 1/2” blade that I use and switch between depending on operation. The 1/2” stays on for the majority of the time, unless I need to cut tighter curves.
