Greetings all,

Patient: Carolina HD-10 horizontal bandsaw , 16tpi wavy-like-hacksaw
93" blade
Typical usage: cutting thinwall mild steel tubing with light-to-
moderate downfeed pressure
Symptoms: all is proceeding normally when suddenly blade starts to
attempt to run out under the guides nearest the motor until the weight
of the downfeed becomes too great and forces it back up against the
top guide bearing nearest the motor with a moderately loud "bang".
This cycle repeats roughly 5 times per second. The wear pattern on the
backside horizontal bearing nearest the motor shows all the wear is on
the bottom edge. The wear pattern on the frontside horizontal bearing
nearest the motor shows even wear across the entire bearing face.

Now the only way to keep the spine of the blade against the top guide
bearing nearest the motor is to apply full downfeed pressure.

Anyone have this happen to them? And if so how did you fix it? What
adjustments did you make to the saw? The positions of the three guide
bearings are fixed within the cast-iron guide block.

What to do?

TIA,

Still-learning Steve
