Excellent work Derek! Serious quality content which doesn’t have a million+ views because caving is such a niche area. I feel your work also has real merit in a professional sense. Not to say that you’re by any means, “an amateur”. But your content can and should be used by paid government/rescue/maintenance climbers that need to delve into crumbling “much-less interesting” yet, important infrastructure.
Thanks for your great content. I am a cave explorer and find it valuable. Content on our niche is not readily available besides a few sources, you being an excellent one!
Thanks, so useful.
Great tutorial!!
Thanks for the video!
Do you use only stainless steel bolts or for some purposes also galvanized bolts, that are cheaper?
Do you have any suggestions how to carry all that equipment in the cave? Do you use some kit-belts just for tools, that you take off in narrow paths? How do you secure tools, to prevent them to be lost in the deep darkness?
I only use, and strongly recommend, stainless steel for all anchors. Using galvanized for rigging is irresponsible. I occasionally use galvanized steel bolts for aid climbing progression, but even then stainless is a better choice because it doesn't leave rust stains and can be utilized later if the placement ends up being good for a rebelay or deviation. I use a PVC or nylon bolt bag to carry rigging hardware. I carry tools in a cave pack until needed, and then I have tethers as a backup for critical tools such as rotary hammer, hammer and wrench.
What was the diameter of the bolt and the drill bit. Should the drill bit be the same size as the bolt, or just a bit bigger?
In these examples I'm placing a 3/8" bolt using a 3/8" SDS bit. There are many different diameter wedge bolts available, in both imperial and metric, but the bolt diameter and drill bit diameter should be the same. When you hammer the bolt into the hole it needs to be a friction fit in order to hold the wedge clip in place during tightening.
What size wrench is needed for 3/8" bolts?
Depends on the bolt. The closest thing to a standard is 9/16", but Fixe nuts take a 17mm wrench.
