Powermatic PM2700 Coplanar Alignment, Verifying that fences are coplanar, Coplanar Adjustment

Coplanar Alignment

Follow steps 1–5 to determine if alignment is necessary. Steps 6–9 will guide you through the alignment if required.

Verifying that fences are coplanar

1.Remove the guard and spindle attachment.

2.Adjust the fence assembly (A) so it is positioned approximately at midpoint and lock

(B).

3.Place a straightedge (F) on the table pressed against the infeed (E1) and outfeed fences (E2).

4.Unlock the fence lock knobs (D1, D2).

5.With the ram adjust dials (C1, C2) adjust the position of either fence as required to bring both fences in-line (coplanar alignment) using the straightedge as the point of reference.

No adjustment is required if both fences are flush with the straightedge as shown in Figure 7. Pro- cede to Ram Dial Calibration (step 00).

Adjustment is required if the fences appear skewed (Figure 8). Continue with Coplanar Adjust- ment (following steps).

Coplanar Adjustment

Determine which fence is skewed (in this example: G1, Fig. 8), which will require adjustment while the remaining fence (G2) will serve as the reference point.

6.Remove both fences and place the straight- edge against the infeed and outfeed fence castings (Figure 9).

7.Lock the reference fence (D2) and unlock the skewed fence (D1).

Read step 8 completely before attempting.

8.Maintain steady pressure of the straightedge against the fence castings (H, Fig. 9). At the same time, attempt to bring both fences into alignment as shown in Figure 10. This is accomplished by alternately making incremen- tal adjustments to four setscrews (L, Fig. 11) on the front face of the casting (K, Fig. 11) with a 2mm hex wrench, followed by repositioning the casting with the micro adjust dial (J, Fig. 11) as required.

Important: It is recommended that the adjustment setscrews (K, Fig. 11) be rotated in 1/16th increments or less at a time.

Alignment is complete when the skewed and reference fence castings are coplanar (in-line) as shown in Figure 10.

9. Replace both fences and secure.
