They make it sound as though you've divined the magic angle for your
bandsaw once and for all. I'm surprised they don't tell you to just
paint the drift angle right onto the table. In fact, the only time I've
heard anyone say that drift angle depends on anything, they said that
it depended on the particular blade... and that *all*!

I commented on Andy's similar question after you posted this.
When you have your fence set up to compensate for drift on a particular
blade it is set up only for that blade and that tension. Depending on the
sharpness, quality, blade size, and BS tension settings another blade may
require difference fence settings to compensate for drift. Drift can be
caused by the blade or the BS it self.

I'm not buying it. So, I gotta ask... in everyone's experience, what of
the following factors will, if changed, change the drift angle of your
bandsaw:

- Blade width

On my old Craftsman saw, Yes.
On my new Laguna, VERY little to no change.

- Blade tension

My old saw, Absolutely
My new saw, none so far.

- Feed rate

Old saw, yes
New saw, no signs yet.

- Hardness of the wood

Old, I don't recall.
New, no change.

- Thickness of the wood

Old, yes
New, resawing through 11", No.

- Grain of the wood

Old, don"t recall.
New, so far with sharp blades, No.

- Height of the upper guide above the wood.

Old, Yes.
New, makes no difference

- Slack in the thrust bearing

Old, Yes.
New, No.


I would think that the wood would make a difference, but nobody ever
seems to suggest using a similar wood of similar thickness and grain
when initially finding the drift angle.

So, what about it? Once I find my drift angle, what can I change
without having to go find the angle again.

If you tried everything, perhaps a new saw will be required to remedy the
problem. Remember, a lot of factors come into play that differ with each
blade. IMHO the more rock solid the saw is the less you will have to tweek
blade tension and for each individual blade.


And are there any other
factors I've missed?

Blade quality? Blade sharpness? Band saw build quality?
