Typically I have no problem with the 1HP on my Delta 14" bandsaw. The
other day I resawed some 7" wide Brazilian Cherry (2820 on Janka
hardness scale vs. 1360 for white oak). I have a 1HP, 14" delta
outfitted with a 1/2", 3 tpi Timberwolf blade. It took about 1 minute
to resaw a 15" length.
I hesitate to push this saw beyond its capabilities, but I have heard
that some of you have installed a 1 1/2 hp motor into this saw. Over
the years it appears that the same saw has gone from 1/2 to 3/4 to 1
HP. I don't know how much more it should be pushed. Has anyone found
the limit that cares to talk about his/her painful experience? Can
those of you that have gone beyond 1 HP give me some feedback as to how
much performance improvement you experienced?
It appears that the saw is probably getting more ill treatment when the
motor stalls with the accompanying jerky startup than if I just had a 1
1/2 HP motor that gave the additional constant stress.
For this effort, I am thinking of sawing the board in half and resawing
a 3 1/2 wide piece just to make it easier on ME and the saw.
I have a Delta 14" Limited Edition which came with a 1 HP Emerson motor.
After it burnt up I replaced it with a Baldor 3/4 HP (hey, you take what you
can get at the time). Since then I've seen no difference in resaw
capability (51/2" Jatoba). A 1/2" x 3 tpi is not the optimum Timber Wolf
blade for resaw, I use a 3/4" x 2 tpi. In the years before the Chinese tool
wars, Delta 14" bandsaws were quite happy with 3/4 HP motors and remember,
Delta invented that saw. The easiest way to say my bandsaw is better than
yours without incurring a lot of re-tooling expense is to just put a bigger
motor on it. I have to hand it to Jet, they did a good job of pushing Delta
to a 11/2 HP motor when all the while Delta knew it wasn't necessary. I can
only justify the increased HP if you put a riser block on it.

Black locust has the same hardness as Brazilian Cherry (2820). I think
I will cut the board in half and see how that helps things. I tuned
the saw up pretty well, but I will go through it again to make
absolutely sure.

My 20" Delta originally came with 1-1/2 HP, but by the time I got it,
it had been upgraded to 2 HP. A capcacitor start/capacitor run Leeson
with integral overload protection.
While the P.O. was upgrading the motor, he also downgraded the motor
control to a common 277 VAC "snap switch", which was never intended for
inductive loads.
Square D makes a two-pole (1 ph) and a 3 pole (3 ph) motor starting
snap switch which fits within the Delta switch box.
Rated 2 HP 1ph, much more than that 3 ph. About $30 for the 1 ph model,
about twice that for the 3 ph model.

Knock yerself out. One horse is good enough to bend a blade.

I have the same saw and used the same blade to resaw black locust. Don't
know it's hardness, but it is plenty tough. Went though 5" like butter.
It is essential that everything is perfectly square and you are compensating
for the drift angle (I didn't have one, with probably helped.) The blocks
and all have to be correctly adjusted.

The standard motor that has been used on the Delta 14" enclosed stand
band saw (domestic) for at least the last three years is 1.5 hp. So
lots of people have them that have not done any modifications. More
HP allows for a faster feed but does not compensate for poor guide
adjustment, improper blade sizing or tension, or a low quality, dull
blade. You should be able to resaw with 1 hp if you are properly set
up.

Jet had nothing to do with it. and feed tests prove that while it is
not "necessary" it is better.
