anchor testing rig 3-Sep-2010 At 1:06:42 PM cruze

I am not following this. You have chosen a high capacity rig to test anchors to failure? Once they have failed you have a dysfunctional anchor in situ (or attached to a piece of rock at the base of the cliff) that will need replacing.

Why not just replace the anchor or not replace the anchor?

If it is to get a general feel for anchor strength (how glue binds to rock in that location and under those conditions, etc) it seems that there are many other variables that can't be determined - how clean a hole was before the first anchor was placed, type of glue used, variations in rock quality from placement to placement, etc. I realise I may have misunderstood your intentions, and overestimated the variability in these variables, but could someone inform me?

I could have been thrown by your initial comments about existing anchors, and perhaps you are just looking to place new bolts under different conditions in random bits of rock to see if their strength can be maximised when actually applied to routes??!!
