Adjusting blade vertical:

The blade guide bearing seat can rotate as needed to make the blade vertical to the saw table. Follow these instructions.

1.With the saw arm in horizontal position, put a machinists square on the table, and against the blade, as shown. The blade should be square (vertical) to the table. If not...

2.Slightly loosen the socket head cap screw which secures the bearing seat to the bracket bar.

3.Use a wrench to rotate the seat until the blade is vertical. (See Figure 13.)

4.Tighten the socket head cap screw securely.

5.Check the other blade guide for vertical. Adjust, if necessary.

6.After adjusting for vertical, RECHECK THE BLADE FOR PARALLEL. Changes in vertical can easily result in changes in parallelism. See Adjusting blade parallelism.

Test cutting to verify adjustment accuracy

Test cuts can be used to determine whether or not you have adjusted the blade accurately. Use 2 inch bar stock to perform these test cuts, as follows:

1.With the bar stock securely clamped in the vise, make a cut through the bar stock. (See Figure 14.)

2.Mark the top of the bar stock.

3.Move the bar stock about 1/4 inch past the blade so you can begin a second cut.

4.Rotate the bar stock 180 degrees so the mark you made is now at the bottom of the cut.

5.Make a cut through the bar stock.

6.Use a micrometer to measure the thickness variation between the top and bottom of the disc you have cut from the bar stock. Unless things are truly perfectly aligned, there is almost certain to be a certain amount of "wedge" to the shape of the disc you have cut. The saw blade can be considered correctly adjusted when the variation measured is no more than .012 inch across the face of the disc.

If you do not have a 2 inch bar stock available for a test cut, use a larger diameter test work piece rather than a smaller one. The maximum thickness variation on any test piece should be no more than .003 inches, per side, per inch of stock diameter.
