Bandsaw Problem

    I cut a kitchen unit kickboard with my bandsaw and since then it is impossible to cut anything straight - the blade just bends/develops an odd angle.

    Has the resin in the chipboard damaged the blade's teeth?
     
  2. before you do anything, try adjusting the blade tension

    Thanks for your reply.

    I did check the tensioning, but the cut still went off at an angle and the motor laboured.

    I also made sure that the guides were correctly spaced.

    Can you scrape anything off the blade ?

    The resin can get hot, melt, then solidify again on the blade.
    This can throw the saw off.



    Mr. HandyAndy - really

    you may find the blade needs tracking. It could be running out of kilter.

    Might be blunt.
    Does the saw labour with no load? If so check for obstructions.

    Not sure how I would adjust the tracking.

    It all started after I cut the chipboard. Someone told me that the blade is not designed to cut such material.

    If I try to cut a piece of softwood, for example, I get a curved cut instead of a straight one. Eventually, the blade gets to such an angle that it stops - or rather the motor does.
     
  8. Its likely that the chipboard has dulled the blade, try another one.

    If the problem persists try adjusting the tracking.

    There will be a screw adjuster somewhere that will change the angle of the wheel, the blade should be running on the centre line of the wheel.

    I have found bandsaw blades never cut straight after they have been used for curves and probably this might also be true of hard resin based man made boards. I suspect the blade has been blunted and this is what is causing it to wander. Replace the blade, as has been suggested, and keep the old one if you ever need to rough cut anything.

    Thanks to everyone for their help.

    I will start by buying a new blade.
