The amount of drift varies with every blade, but you can compensate for it by clamping your fence to match the drift angle. SINGLE-POINT FENCE. Another way to overcome blade drift is to use a single-point fence like the one shown in the left photo above and in the margin. SETTING THE FENCE TO COMPENSATE FOR BLADE DRIFT. FEED RATE & TECHNIQUES. With either style of fence, your saw will help you determine the feed rate for resawing.
Band saw blade drift is a tendency of the blade to veer to the left or right while making a cut using the rip fence. The point of the last paragraph is that if the band saw is not set up properly and/or does not have a good quality, sharp blade installed and tensioned correctly, the chances of accurately adjusting for drift are minimal at best. Since there is little that we can do about blade drift at the blade, we adjust the fence to match the drift angle to essentially cancel it out.
04-08-2020, 4:21 PM #3 Yes, if your blade has drift and your fence is not set at the drift angle then the cut will try to follow the drift angle and push the workpiece towards or away from the fence. 04-08-2020, 4:30 PM #4 I think the absolute best way to avoid drift with a fence is to tune up your band saw, although you can measure the drift and create an angle compensator, which is old school. So you can start with a well set up saw with no drift and after cutting a bunch of curves or changing blades start getting drift.

how to adjust bandsaw fence for drift Related Question:
Why does my band saw drift?
Drift is cause because the blade buckles under the load. You can see that by stretching a ribbon between 2 points and applying a pressure to one of the edges, it will turn sideway easily. A sharp blade and high blade speed will help a lot with that.
Why does my bandsaw cut to the left?
When the band saw cuts crooked, a dull blade, improper feeding, loose blade tension or not using a work piece guide could be the cause. Use the rip fence or miter gauge to guide the work piece uniformly through the cutting blade to make straight cuts.
How tight should my bandsaw blade be?
The blade should deflect no more than 1/4 in. A good place to begin is to tension the blade until the meter reads proper tension for the next wider blade. For example, if you’re tensioning a 3/8-in.
Why does my bandsaw spark?
Ceramics can cause sparks. Or, if your thrust bearing is too far past the blade, more toward the center of the bearing than the edge, then it won’t turn and you’ll get sparks too, and possibly wear a groove in the bearing.

Adjust blade guard height to about 3 mm or 1/8 inch to 6mm or 1/4 inch above the top of the material being cut. Wider gaps will place tension on the blade and increase the risk of breaking. Ensure the blade is tracking correctly and runs freely in and against the upper and lower guide rollers.
