11.7 Fixed Gages and Extra Stops

11.7.1 Challenge Standard Fixed Gages

These fixed gages with pre-cut hole-spacing fit on the side guide in place of the movable stops. To
use, simply loosen the setscrews holding the adjustable stops and slide them out of the way. They
may either be removed from the backgauge or slid to the extreme right end of the scale where they
will be out of the way and cannot become lost. Slide the fixed gage into the backgauge from the left
end, making sure that the slanted lead for the stops is to the left. Position the gage so that the right
end lines up with the dimension on the scale for the centerline of the first hole to be drilled. Tighten in
place with the two setscrews. Actual operational use of the stops on the fixed gage is the same as
using the adjustable stops.
These fixed gages are available from stock in the following standard types:
22-stop Gage, 1/2" centers (for multi-ring binders)
25-stop Gage, 3/8" centers
25-stop Gage, 1/4" centers
34-stop Gage, 1/2" centers
46-stop Gage, 3/8" centers
50-stop Gage, 1/4" centers
Special fixed gages with any desired hole spacing can also be supplied. In ordering be sure to
specify the number of stops (holes) and the hole spacing. A sample of the job to be drilled or a
drawing of the hole spacing is helpful. Also, specify machine model and serial number.
