Blade Lead - Grizzly G0803 Owner's Manual

Blade Lead

Bandsaw blades may wander off the cut line when
sawing, as shown in Figure 59. This is called
blade lead.
Blade lead is usually caused by too fast of a
feed rate, a dull or abused blade, or improper
blade tension. If your blade is sharp/undamaged,
properly tensioned, and you still have blade lead,
perform the following procedures.
Figure 59. Example of blade lead.
To correct blade lead:
1.
Make sure blade is properly tensioned and
blade guides are adjusted correctly.
2. Use less pressure when feeding workpiece
through cut.
3.
Make sure miter slot and fence are parallel to
blade line (see Aligning Table and Aligning
Fence procedures for detailed information).
4. Perform test cut with bandsaw.
— If there is still blade lead present, compen-
sate for this condition by skewing the fence
or shifting the table, as instructed in the
following procedures.
G0803 (Mfd. Since 09/15)
To skew your fence:
1. Cut a piece of scrap wood approximately
thick x 3" wide x 17" long. On wide face of
board, draw a straight line parallel to long
edge.
2. Slide bandsaw fence out of way and cut
along the line halfway through the board.
Turn bandsaw OFF and wait for blade to
stop. Do not move board.
3. Clamp board to bandsaw table, then slide
fence over to board so it barely touches one
end of board.
4. Use a 4mm hex wrench to loosen the two
fence adjustment cap screws, skew fence
so that it is parallel with scrap piece, then re-
tighten cap screws.
5.
Make a few cuts using fence.
— If blade lead is still present, repeat Steps
1–4 until blade and fence are parallel with
each other.
