G0621 Wood/Metal Bandsaw
-41-
To ensure accuracy when cutting stacked
workpieces, the table should be 90˚ to the back of
the blade as shown in
Figure 47. If the table is not
perpendicular to the back of the blade, the table
needs to be shimmed.
Shims can be made of any durable object that
can be sandwiched between the table and the
trunnions. We recommend using shim washers or
shim stock because of the wide range of available
thicknesses. These items can be purchased at
your local hardware store.
Figure 47. Squaring table to blade back.
To shim the table:
1. Make sure that the blade is tracking properly
and that it is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Loosen the trunnion bolts that secure the
trunnions to the table.
4. Place shim stock between the table and the
two trunnions to shim the table in the desired
direction.
Note: Another way to shim the table is to add
washers between the table and the trunnion.
5. Follow the Aligning Table instructions on
Page 23 to complete this procedure.
"Blade Lead" means that the blade does not cut
straight when using the fence or miter gauge (see
Figure 48). This is a common condition with all
bandsaws. Worn or damaged blades may cause
lead and replacing them will fix the problem. Still, if
your bandsaw is setup correctly and lead occurs,
compensate for it by skewing the fence.
Figure 48. Blade leading away from line of cut.
To correct blade lead, do the following steps
and make a test cut before skewing the
fence:
1. Ensure that you have proper blade tension
(refer to Page 19).
2. Ensure that the blade guides are adjusted
correctly (refer to Pages 19 & 21).
3. Ensure that the miter slot or fence is parallel
to the blade (refer to Page 23).
To skew your fence:
1. Cut a piece of scrap wood approximately 3 ⁄
4
"
thick x 3" wide x 17" long. On a wide face of
the board, draw a straight line parallel to the
long edge.
2. Slide the fence out of the way and cut free-
hand along the line. Stop at the halfway point.
Turn the bandsaw
OFF and wait for the blade
to stop.
