Default Bandsaw speed

I have a Griz 14" bandsaw with riser. Nearly all I do is cut out bowl
blanks from green, wet wood, average thickness 5-6 inches. I use
Timber Wolf 3/8" blades 3 tpi. Now for the question. I have always
run it on the low blade speed. Has anyone used the high speed for
such work? It is wired for 220 and never really bogs down on the low
speed but was wondering there is any advantage of a faster blade speed.


Blade speed is a careful dance with blade tension, and feed rate. Part of
blade speed is the mechanical factors in your saw, the bearings for the
wheels, and the tires on the wheels, and the tension keeping the blade
straight. Part of the blade tension is again, mechanical factors in your saw
- notably the bearings - and then there is the weld in the blade and when it
will let go - plus the continual flexing of the blade and the shape of the
notch at the bottom of each tooth and the likelihood of a work-hardening
failure at any tooth notch. Faster blades will also heat up faster and
hotter, accelerating the work hardening thing.
In general, the saw manufacturer has probably considered some of these issues
in establishing the blade speed for the given saw. You can go slower,
depending on the nature of the item being cut, but faster is not always
better.
Blade tension is another variable, which you may have control over, and
Timber Wolf may have a nice tutorial on that issue in its sales literature.
