+<img src="hand_bolting_guide/img_2990.jpg" /><p>Before you start drilling, "dress" the rock; that is, hammer away the flaky top surface of the rock and flatten out a small area around where your spit is to go.</p>

+<img src="hand_bolting_guide/img_3001.jpg" /><p>It also helps to give the driver a tap to remove dust caked up on the end.</p>

Notice that this spit is rather deep in, and would probably be rather hard to use for a rigging bolt; more dressing would be needed as well. This bolt was actually for the tag on cave 2005-07, and tag bolts clearly needn't be all that strong.</p>
