It is (according to the caption) ?1000s worth of what look like BP anchors. I took it from the Dorset Bolt Fund's facebook group; by my extremely brief counting there are most of 200 bolts there by my reckoning. The Dorset Bolt Fund, like virtually all climbing bolt funds, only replaces old bolts rather than placing new ones; virtually all new climbing bolts are placed and paid for by individual climbers out of their own pockets. Equally they buy their own drills. There is no national bolt scheme (for placing new bolts), there is no bolt approval process, there is no training. People place by consensus so it is mostly new resins, but through bolts are also placed. Some of the bolts (particularly on Portland) are homemade resin U-staples, but are still more bomber than the rock normally!
Climbers place way, way more bolts than cavers do. Caving is a niche activity for resin bolting; there are far fewer cavers and they use far fewer bolts than (sport) climbers. Consequently I can understand why a) it isn't completely unaffordable for the BCA to buy bolts, and b) while it is clearly time-consuming (and probably reinventing the wheel in my eyes) the BCA can spend the time testing anchors.
So if the problem is a lack of cash for anchors, then cavers should put there hands in their pockets (I have donated to climbing bolt funds and would happily donate to caving ones).
If the problem is the supply of IC anchors, then use something else? There are plenty of other resin bolts available that have been used in climbing for years.
If any one volunteer is overloaded, delegate to others (the anchor project should not be reliant on any one person).
In my eyes the only acceptable problem is the absence of volunteers, and again in my eyes if this is the problem then anyone who complains can be assumed to be volunteering, right?
