Delta 78-055B Attaching Rails to Extension Table, Attaching front rail to the extension table

Attaching RAILS TO EXTENSION Table

NOTE: Do the next steps in order presented. The extension table and main saw cast iron table must be level and flush to ensure smooth operation of your fence. To get the table level, it is important to attach the pieces in this order:

1.Front rail to the extension table.

2.Rear rail to the extension table.

3.Rear rail to the Unisaw. Though it is already attached, tightening this hardware firmly is the last step.

NOTE: Re-check and make sure the hardware used to attach the rear rail to the Unisaw is only finger tight and allows slight movement of the rear rail up and down.

Attaching front rail to the extension table

1.Position the leveling foot (U) Fig. 13 on the front of the saw until the holes (not visible) in the extension table line up with the holes (EE) in the front rail. (NOTE: 52" (1.3 m) version shown in Figure 13.)

NOTE: Place guide tube (FF) across saw table and onto extension table as shown in Fig. 13. If there is a gap (as shown) the leveling foot (DD) needs to be adjusted to bring the table up more.

2.Insert a 1/4-20 x 3/4" (19 mm) flat head screw into one hole (EE) Fig. 13 on front rail. Place a 1/4-20 serrated flange nut on the screw from underneath the extension table.

3.Repeat this for the remaining holes (EE) Fig. 13 in the front rail.

4.Using template (Z) Fig. 14, check rail position at left side of table as shown, then the right side. Then re-check both left and right side after tightening. The gauge must be fully on the table and just touch the rail surface. See inset Figure 14.

5.When positioned as described above, the horizontal portion of the rail should be down from the top of the table surface 2-7/8” (73.03 mm). Tighten the front rail mounting hardware when you are certain the rail is set at the proper depth. See inset Fig. 14 for cross-section showing where to check for flush.

Attaching rear rail to extension table

NOTE: Do not use template to set rear rail.

Use the same hardware and procedures from steps 1-3 in section Attaching Front Rail to the Extension Table, attach the rear rail to the extension table.

NOTE: Instead of leveling foot (U) Fig. 13, you will position leveling foot (V) just prior to installing rear rail fasteners.

Attaching rear rail to the Unisaw

Fully tighten the two (2) 3/8-24 x 1" (25 mm) hex head screws that attach the rear rail to the Unisaw.

Tightening jam nut on leveling feet

Once feet are set, tighten jam nut (HH) Fig. 14A up against leg body.
