Inspection of gaffs and the leg iron stirrup
EDELRID gauge is to be used to examine and adjust the length,
outline and sharpness of gaffs, as well as the width and thick-
ness of the leg iron stirrup.
In normal use, your gaffs will need only honing to retain their
cutting edges.
When gaffs are nicked or otherwise damaged from contact with
pole hardware, or have been severely worn and re-shaping be-
comes necessary, a single cut file has to be used, together with
the EDELRID gaff gauge, which is available separately (article
number 889470000100).
To assure proper sharpening, follow the instructions.
Pole and tree climber gaffs have to be carefully sharpened in
order to reduce the possibility of "cut-outs" or tip breakage that
could cause serious injury or death from a fall.
The gaff gauge can be used for both tree and pole gaffs. When
short gaff are checked, feature on the left side of the gauge
have to be used, when long gaffs are checked, features on the
right side have to be used. fig 8 (gauge)
1. GENERAL GAFF INSPECTION
Carefully check that the gaffs are free of deep scratches,
dents, cracks or irregularity.
2. GEOMETRY CHECK – GAFF THICKNESS
Insert the gaff in the gauge opening marked with GT1 as far
as possible. Make sure that the flat­bottom part of the gaff
is lying on the gauge base surface. The point of the gaff now
should lie in the "OK" rectangle. If it does the gaff has proper
thickness, if not the gaff has to be re-sharpened or dis-
missed. If the gaff fails to reach the "OK" rectangle, it means
it is too thick. In this case carefully file the inside flat surface
of gaff to reduce thickness. If the gaff reaches beyond the
"OK" rectangle, it means it is too thin. To correct this, file the
gaff tip or radius. Repeat the same check procedure with the
opening GT2. See fig 9 (GT1 check)
3. GEOMETRY CHECK – GAFF WIDTH
Insert the gaff in the gauge opening marked with GW1 as far
as possible. Make sure that the flat­bottom part of the gaff
is lying on the gauge base surface. The point of the gaff now
should lie in the "OK" rectangle. If it does the gaff has proper
width, if not the gaff has to be re-shaped or dismissed. If the
gaff fails to reach the "OK" rectangle, it means it is too wide.
In this case carefully file the inside flat surface of gaff to
reduce thickness. If the gaff reaches beyond the "OK" rect-
angle, it means it is too thin. To correct this, file the gaff tip
or radius. Repeat the same check procedure with the open-
ing GW2. See fig 10 (GW1 check)
4. GEOMETRY CHECK – GAFF PROFILE
Place the tip of the Gaff in the notch marked with PROFILE.
The gaff profile should follow the gauge outline to assure a
proper rounding of the tip, if not the gaff has to be re-shaped
or dismissed. See fig 11 (gaff profile check)
5. GEOMETRY CHECK – GAFF CUTTING EDGE
Place the gaff tip on the little V notch marked with CUTTING
EDGE. From the tip for 5 mm only the cutting edge should
touch the side of the groove. See fig 12 (gaff cutting edge
check)
6. GEOMETRY CHECK – GAFF LENGTH
Place the gaff on the gauge where GAFF LENGTH is writ-
ten, with the gauge underside of the gaff touching the
gauge, and the gouge outline as deep as possible toward
the stirrup. Long gaff should lie on in the LONG GAFF
LENGTH "OK" rectangle. Short gaff should lie in the
SHORT GAFF LENGTH "OK" rectangle. If the gaff is to
short, it has to be dismissed. See fig 13 (gaff length check)
7. GEOMETRY CHECK - LEG IRON STIRRUP THICKNESS
Try to fit any point of the leg iron stirrup in the STIRRUP
THICKNESS notch. If it fits into the thin long notch marked
as "NOT OK" the climber is to worn and has to be replaced.
See fig 14 (leg iron thickness check)
