Blade Lead - Grizzly G0636X Owner's Manual

Blade Lead

Bandsaw blades commonly wander off the cut
line when sawing, as shown in Figure 41. This is
called blade lead. Blade lead is commonly caused
by too fast of a feed rate, a dull or abused blade,
or improper tension. If your blade is sharp/undam-
aged and you still have blade lead, perform the
following instructions.
Figure 41. Example of blade leading away from
line of cut.
To correct blade lead:
1. Use less pressure when feeding workpiece
through cut.
2.
Check that miter slot or fence is paral-
lel to blade line, and correct if necessary
(See Aligning Table, Page 28 and Aligning
Fence, Page 29).
3.
Check for proper blade tension. If blade ten-
sion is correct and it is not convenient to
replace blade, compensate for lead by skew-
ing fence or adjusting table.
To skew fence:
1. Cut a piece of scrap wood approximately
thick x 3" wide x 17" long. On a wide face of
the board, draw a straight line parallel to long
edge.

2.
Slide bandsaw fence out of the way and cut
halfway through board on line by pushing it
into blade. Turn bandsaw OFF and wait for
blade to stop.
3.
Clamp board to bandsaw table without mov-
ing it. Now slide fence over to board so it
barely touches one end of board.
4. Loosen two cap screws that secure fence rail
to underside of table (see Page 29).
5.
Skew fence so it is parallel to edge of scrap
piece.
6.
While maintaining skew, tighten cap screws
loosened in Step 4.
7.
Make a few cuts using fence. If fence still
does not seem parallel to blade, repeat
Steps 1–6 until blade and fence are parallel
with each other.
To shift table:
1. On a scrap piece of wood, mark a line that is
perpendicular to front edge.
2.
Cut halfway through board on line by pushing
it into blade.
3. Turn bandsaw OFF and wait for blade to
stop.
4. Using an 8mm hex wrench, loosen four cap
screws that mount table to trunnion (see
Figure 31). Shift table to compensate for
blade lead, then retighten cap screws.
5. Repeat Steps 1–4 until blade cuts straight.
