Hi, The titanium 'Tortuga' bolts manufactured by Liberty Mountain works are no longer in production. I have been in contact with Chris McNamara from Liberty and he will let us know if they come back online with that product. These bolts also cost $7+ not including shipping! They will last a very long time, just how long is unknown as none have been in long enough to show any signs of wear! Probably in excess of sixty years?
The lifespan of glue in stainless anchors is also much longer than the mechanical anchors, Stainless glue in anchors removed (as a matter of course) after thirty years in a seaside location in the States were all still in good working condition. Hence the ARFs choice to go this route. All the crags I visted in France recently are being re-equipped with glue ins. It is however (as shown above) much, much more expensive.
Chris also suggested that we start manufacturing Titanium bolts locally. Titanium is exceptionally difficult to work, you need to find exactly the right grade and the right people, properly equipped to handle the work. So again: anyone know of titanium experts who could advise the way forward from here?
PS Any thought of using galvanised mild steel is totally ludicrous!! Anyone still using this junk needs to severely reprimanded! And no it is not acceptable inland either. Creating an epic replacement task for the poor guys who have to come and clean up your mess, just to save yourself a few bucks is totally uncool! If you are struggling to afford the cost of equipping your line properly then just ask for help.
