3-14 CHANGING BUTT SPACING:
SETTINGS & ADJUSTMENTS
From time to time you may need to change your butt spacing on an existing index bar, or set up a
new index bar. To accomplish this, the following procedure is suggested:
1. If changing an existing index bar, use a metal scribe, mark the location of the index blocks when they
are set for your standard spacing so you can accurately and quickly return them to standard.
2. Place the “non-standard” or “set-up” door in the machine, roll it to the proper door stop and clamp it.
3. Starting at the top of the door measure down the door edge and make a mark where the top of each
butt is to be located.
4. Loosen the set screws in the router index blocks.
5. Lower router carriage until the locating dog on the router carriage is over the index block nearest the
top of the door, and the router carriage is resting on the door.
6. Slide router carriage back and forth until the applicable “butt reference line” on the door clamp bar is
properly aligned with the mark on the door nearest the top of the door, see figure 3.7.
7. Move the door while holding the stop to tighten set screws in router index block.
8. Clamp router carriage to door and check to make sure that the lines are still aligned. Repeat the pro
-
cess for the other butts.
9. If frequent changes in butt spacing are made, we recommend the purchase of a second index bar with
six index blocks and two door stops. The entire index bar can be quickly changed by releasing the
locking clamp mechanism.
