<p>Wookey demonstrating the technique of drilling a hole for an anchor with the
|
|
Bosch cordless rotary hammer drill. Note that he is using both hands on the
|
|
drill, so must be securely wedged in place using feet and/or the rope. Since
|
|
it was given to CUCC in <a href="../../years/1990/sponsr.htm">Sponsorship</a>
|
|
in 1990, the power drill has proved particularly useful on pitches where many
|
|
rebelays are needed, and especially on bolted climbs or traverses such as "<a
|
|
href="../../1623/161/l/3wisea.htm">Three Wise Men</a>". The drill was in
|
|
such demand for this type of rigging that a second one was bought (and a third
|
|
may be borrowed...), and a number of members of the club have invested in
|
|
drills for their own use [1990].</p>
