Why does my bandsaw blade wander?
Similarly, it is asked, why does my bandsaw blade keeps coming off?
the blade tension can warp the casting.. so check the alignment with the blade under tension, plus some more tension to account for the additional blade tension due to the cutting forces. basically overtighten the blade, adjust the alignment, back off some, and it should run true.
Besides, how tight should a band saw blade be?
Bandsaw blades require tension and lots of it to consistently produce straight, uniform cuts, especially in thick or dense stock. Most blade manufacturers recommend 15,000 psi to 20,000 psi for a common carbon-steel blade.
Blade is Dull Unsurprisingly a dull blade will not cut as well as a new sharp blade. You might expect that a dull blade would cut more slowly, but it is also more likely to cut crooked. When the bandsaw blade is sharp it does not take the operator much force to push the workpiece into the blade and get a cut.
