PREPARATION - CUTTING THE GEAR RACK
CUTTING THE GEAR RACK
Gear Rack Cutting Rules
•
Total length of gear rack equals total rail
length minus 10.5 inches.
•
The shortest length a section of gear rack can
be cut is 22 inches long due to the spacing of
the screws.
•
Each section of gear rack must have at least
two mounting screws.
•
If the required length measures to the middle
of a gear tooth, make the cut at the nearest
tooth root (the thinnest part of the gear
teeth).
•
If the cut falls on a screw hole, increase the
length by one tooth.
Each section of gear rack is 46" long.
1. Use the Gear Rack Configuration Form to determine
the length of the gear racks.
Total Rail Length =
minus 10.5 inches
(Total gear Rack Needed) =
(Smallest Possible Length) minus 22 inches
(working inches) =
divided by 46
number of full gear rack pieces
remainder
If remainder is < or = 24 inches, add this to the
22 inch cut. You will only need to make one cut.
If remainder is > 24 inches, cut one piece at
remainder and one piece at 22 inches. You will be
making two cuts.
