Resawing with bandsaw

[mikeb]

What causes the board I am resawing to start out the correct width and then become wider as I push it through. The fence is set correctly and I am using a feather board.

I think that what you are experiencing is often referred to as "blade drift" and needs to be compensated for by adjusting the fence. Search the forum and you will find several thread discussing this.

What blade are you using?
What species of wood are yo cutting?
What is the intended thickness?

On a 3' or so long board, scribe a straight line where you intend to cut. Now cut down that line about half way (FREEHAND)(NO FENCE) and then stop. Turn everything off. Don't move the board you just cut. Study its position on the table. You will likely find that it is not square to the blade or what would have been the fence line if there had been a fence. Bandsaw Blade Drift.

What blade are you using? A lot of time band saw blades will drift while cutting. Each different blade is different but any given blade has a consistent drift. The band saw fence needs to be set at an angle to compensate for the drift. There should be a Saw Dust Session on youtube on haw to determine the drift for your particular blade and how to set the fence. Someone will chime in with a link I hope. Watching the video will be easier than trying to explain it here.

You are experiencing bandsaw drift. Many reasons for this as well as solutions. Do a quick internet search. From my experience, a new sharp blade drifts very little compared to a dull one.

+1 on the dull blade causing drift, bowing, etc.
Also, too many teeth per inch can exacerbate blade heating and the problems that come with it. Resawing blades should be fairly coarse-toothed.

I hope this helps.

Heed all of the above with emphasis on the sharp and “correct” blade. Keep in mind the blade drift will change as the blade loses its sharpness and it’s a good thing to check it every so often.
