Every now and then, it’s a good idea to check your band saw table for squareness to the blade. Here’s the quick method I like to use: take a piece of flat, square-edged scrap and cut a shallow kerf into one edge. Now pivot the block around so the kerf faces the back of the blade.
If you can slip the kerf into the blade from the back side, you know the table is square. But, if the cut doesn’t line up the table needs some fine-tuning with a combination or engineer’s square. Try the kerf-cutting trick again to check your adjustments once you’re done.
