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.
G0621 Wood/Metal Bandsaw
"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.
