Cutting Curves

When cutting curves, simultaneously feed and
turn the stock carefully so that the blade follows
the layout line without twisting. If a curve is so
abrupt that it is necessary to repeatedly back up
and cut a new kerf, use either a narrower blade
or a blade with more TPI (teeth per inch), or make
more relief cuts.
Always make short cuts first, then proceed to
the longer cuts. Relief cuts will also reduce the
chance that the blade will be pinched or twisted.
Relief cuts are cuts made through the waste
portion of the workpiece and are stopped at the
layout line. As you cut along the layout line, waste
wood is released from the workpiece, alleviating
any pressure on the back of the blade. Relief cuts
also make backing the workpiece out easier, if
needed.

Blade Lead

It is common for a bandsaw blade to wander off
the cut line when sawing as shown in Figure 59.
This is called blade lead.
Figure 59. Blade leading away from line of cut.
To correct blade lead:
1.
Check that the miter slot or fence is parallel
to the blade line, and correct if necessary.
2. Check for proper blade tension. If the blade
tension is correct and it is not convenient to
replace the blade, compensate for lead by
adjusting the table.
To shift the table:
1.
On a scrap piece of wood, mark a line that is
perpendicular to the front edge.
2. Cut the board on the line by pushing it into
the blade with the miter gauge.
3. DISCONNECT BANDSAW FROM POWER!
4. Loosen the table mounting bolts. Shift the
table to compensate for the blade lead.
5. Repeat Steps 1-4 until the blade cuts
straight.
6.
Tighten the table bolts.
