Extrem ice axe modifications
On every ‘real’ expedition there need to be smart modifications on the equipment. In our case the ice tools had to bite the dust. They got additional wings wich converted them into real multi-tools. God what can you all do with them: dig holes, sit on it, bury scat, blind penguins with sunlight, go sledging… Our climbing elite has hopes to drill through overhanging cornices near the summit — let them do, as long as I do not get hit by the stuff they dig out. Furthermore, you can hit your head pretty good with those things while climbing. Okay, if you came all the way until here you probably want to know all the details. Well, then here you have the technical details for potential cornice drill technicians (mothers and kids can stop reading here): plank sheet on it, screw it tight, done — ‘Keep it simple’. Surface of the wing is approximately 150 x 100 mm at 152 g additional weight. |
Some joyful pedants might object and say that such security relevant tools should also provide safety against bending and shifting. Well, this wonderful construction is providing these features basically automatically. The countersink screw is pulling the 2mm aluminium plank sheet into the oversized holes of the ice tool when thightened. For that purpose the tool got additional bevels to ensure the construction reaches the so called form closure to prevent bending and shifting at least in the hands of the average climber. Furthermore, stability of the plank sheet increases due to the bolted fastening because it neatly follows the curvature of the mattock. In principle this should also work with mattocks that have elongated holes or bigger keyways. If applicable an additional plank sheet needs to be mounted as counterpart. Well, you will make it — worst case you have to stop just beneath the cornice. |
