Fence Adjustment

Blade Lead

 

 

 

 

 

 

The fence slides along the rail for adjustment and secures in place by tightening the star knob.

If you notice that the fence is not parallel to the blade, it can be adjusted where the rail mounts to the bottom of the table.

To adjust the fence so it is parallel with the blade:

1.With a different saw, cut a board to 1" x 4" x 28". Down the length of the board, joint one edge perfectly straight, or rip a narrow strip off the length of the board with a table saw.

2.On a wide face of the board, draw a straight line parallel to the jointed/ripped edge.

3.Slide the bandsaw 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.

4.Clamp the board to the bandsaw table with- out moving it. Now slide the fence over to the board so it barely touches one end of the board.

5.Loosen the two hex bolts that secure the fence rail to the underside of the table.

6.Skew the fence left or right so it is parallel to the edge of the scrap piece. You may need to re-adjust the fence locking mechanisms to gain maximum adjustment.

7.While maintaining the skew, tighten the rail mounting bolts.

8.Make a few cuts using the fence. If the fence still does not seem parallel to the blade, read the “Blade Lead” instructions, or repeat steps 1-7until the blade and fence are par- allel with each other.

Sometimes the bandsaw blade will not cut straight even when the fence and blade are par- allel (see Figure 17). This condition is called “lead.” Lead occurs (1) if the blade tension is incorrect, (2) if the teeth are dull on one side, or

(3)if the teeth are set heavier on one side of the blade than the other.

If you determine that your blade is causing lead problems, you should consider:

Checking/adjusting the blade tension

Replacing the blade

Sharpening the blade

Skewing the fence to match the lead

Attaching an aftermarket or shop made resaw fence attachment.

NOTICE

If the table is shifted, the fence will be affect- ed since it is attached.

NOTICE

Lead adjustments will change when new blades are mounted in the saw.
