No problem. 2horspower is still pretty weenie.

It depends. Most 14" bandsaw have a problem providing enough tension for a
3/4" blade without the frame flexing. Given a situation where a 2 HP motor
would be beneficial, unless the saw was designed to handle that size motor,
the frame of the saw would most likely flex, dropping the tension on the
blade and result in a barreled cut. Hopefully that's the worse that would
happen.

The motor horsepower shouldn't be of any concern (unless too small.)
I'd think the size of blade and the resultant tension required would
be the limiting factors.

Blade friction. When you start resawing lumber where the power is needed a
larger motor, say 2 HP will torque the frame. It will still pull the blade
through the wood but with the flex the blade will "bunch up" above the drag. A
smaller motor will stall before this happens. With my G1019 with the riser i got
the distinct impression from Grizzly's tech support it would be risking snapping
the frame with a 2 HP motor.

Blade friction?!? The motor drives the lower wheel which drives the
blade and the upper wheel goes along for the ride. Whether you have
a 0.5 or a 5.0 hp motor should make little difference, since the
weight of the blade and upper wheel will be the same mass no matter
what motor.


Grizzly's tech support was iffy on a 1.5 HP on my G1019 and had a definite
"no" on a 2 HP.

Did they say why? Were they saying no to the combo or to the larger motor? My
guess is the former, not the latter.

If you mean the combo of the G1019 and a 2 HP motor, yes the saw was designed
for a 3/4 HP motor. I don't know if the riser kit figured in, but I imagine it
would. The tech says a 1 HP wouldn't be a problem, 1.5 was questionable and 2
HP was out.

No, I meant the wider blade and higher tension. But did you tell him
you'd be using low-tension Suffolk Timberwolfs? (Or were you?) How
much difference in mass could the longer/wider blade make? 8 ounces?
That slim margin would easily be quintupled by extra tension on the
original bandsaw with the original spring. Inertial mass _can't_ be
it.
