Link belt did alot in the way of stopping the movement of the
saw. Recommend you try that Bay Area Dave... After I
removed the motor and set it up clamped to a stool (to isolate
what was exactly was at fault) I also tried the old belt on it.
Not good...

But the good news is, without the motor touching any part
of the saw's cabinet, the saw ran really, really smoothly.
I couldn't feel much of anything. Now I know the wheels
are balanced fine, its the motor causing all the vibes.

Next, I shall seek out the cast iron sheave.

The software said it ran under Windows 98/NT/2000, or better.
So I installed it on Linux...

I also followed Todd Stock's advice - Cast Iron Sheave, link belt -
problem solved.

David,

Have you replaced the alloy sheave (pulley) with a cast iron one? I
too bought the 28-299a and had a vibration problem. I followed the
advice of Todd Stock from an earlier wreck posting:

You did get the best of the 14" saws, but in adding power to the
package, Delta made a cost engineering change that moved them in the
direction of the imports, quality-wise.
The problem with the new Delta 1.5 hp is that they up'd the motor speed
from 1750 to 3450 (to keep the price point for the motor and drive train
identical to the old 28-299) and replaced the excellent balanced steel and
iron pulleys that were supplied with the old 3/4 and 1 hp saws with the same
crappy cast alloy sheaves that the Jets and other imports are using. This
drive train vibe is more noticeable than on the imports because speed is
doubled and power is higher on the new Deltas.
Junk the alloy sheave (the motor is likely a machined steel sheave and
is probably OK) and invest in a cast iron, balanced Browning sheave for the
driven shaft - about $28 from MSC. Make sure you get the proper bore (3/4")
and correct 4L pitch diameter (NOT the same as the outside diameter).
Also - swap to a link belt. These are the fixes that Iturra recommends
for the Jet and other imports, and appears to be necessary for the new Delta
1.5 hp as well.

The vibration is my machine with the cast iron sheave, the Fenner Link
belt, and a quality (Woodslicer) blade is nil to undetectable.

Hell, maybe I should bolt my bandsaw cabinet into the concrete floor
(to maintain alignment) then bolt the motor into a thick wood base
(bolted
to floor). The motor would not be physically connected to the saw, only
the belt would connect them. :-) Vibes aren't likely to transmit
through
a belt, only the motor mount if its connected to the saw base.
Just an idea. I tend to get crazy ideas when I get no satisfaction from
an
expensive tool.
