Blade.Lead
Bandsaw blades may wander off the cut line when sawing,
as shown in
Figure.53
. 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.
To.correct.blade.lead,.do.these.steps:
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, compensate for
this condition by skewing the fence or shifting the
table, as instructed in the following procedures.
Figure.53.
Example of blade lead.
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 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.

3" wide x
3
⁄
4
" thick. On wide face of board, draw a
