What factors affect bandsaw drift?
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:
I had some trouble with my Jet 14" shortly after I bought it. What I
did to correct the drift:
1. Remove blade and clean tires (my saw was pretty new - if tires are
older, replace)
2. Remove guide blocks and sand to a smooth and square edge
3. Install new blade - making sure that blade is centered on tires
4. Check tension setting - my saw seems to cut straighter with a bit
higher tension than specified for the particular blade width
5. Adjust guide blocks - just shy of touching the blade on the sides,
and just behind the teeth
6. Set thrust bearing so that even the slightest pressure on the blade
will cause the bearing to spin.
After doing all of this, the saw cuts pretty much dead on straight.
I'd say the two most important things to look at are centering the
blade on the tire and properly adjusting the guide blocks/bearings.
(assuming the blade is in decent condition)
