The cracking of the resin, which ultimately leads to the formation of a crevice, can be caused by glue-in anchors that are flexible or deformable

The cracking of the resin, which ultimately leads to the formation of a crevice, can be caused by glue-in anchors that are flexible or deformable. The useful life of an anchor made of plated steel or stainless steel is likely to be shortened as a direct result of the fact that corrosion thrives in cracks and crevices. It is essential to give some consideration to the manner in which the gate at the bottom and the gate at the top of the quick draw will rest against the rock in this location.

The second step in correctly positioning titanium bolts is as follows:

In order to correctly position the Eterna bolt, you will first need to drill a hole in the location where you want the top shaft of the bolt to be. The hole should be 10 millimeters deep and 14 millimeters wide. Drilling a total of three pilot holes along the 45 millimeter line should be all that is required when using a bit with a diameter of 14 millimeters. Return to the first hole used to create the pilot hole, angling the drill bit so that it rests on the bottom lip of the hole, and then drilling downward at an angle while simultaneously drilling out the space between each hole until you are left with one vertical trench. In accordance with the findings, the yield strength of the bolts that were trenched increased by approximately fifty percent, going from a load of approximately ten to eleven thousand newtons to a load of approximately fifteen to sixteen thousand newtons. This hole has the potential to be over-drilled by approximately 5 to 10 millimeters under normal drilling conditions.


When working with steep rock, over drilling can be problematic because it increases the likelihood that the bolt will fall out of the hole. This is a problem because over drilling increases the likelihood that the bolt will fall out of the hole. The Eterna bolt has a one-of-a-kind design feature that makes it possible to install it on steep rock in a more expedient and straightforward manner:

At the number 9, affix a piece of tape to the end of the drill bit. To ensure that the bolt has a secure interference fit and is installed correctly, give it a few light taps with the appropriate hammer over the last 15 millimeters as you are installing it. Instead, you should make use of a hammer made of titanium, which was designed especially for use with titanium.

The following constitutes the installation of the titanium bolts in the fourth step:

Verify that the bolt can be inserted into the hole without any difficulty. By drilling down on the ledge that serves as the bottom of the trench, it is possible to obtain any additional length that may be required. Because of the increased stiffness, it also has the effect of significantly lessening the effects of fatigue brought on by normal use. This is due to the fact that it is more resistant to deformation. You could also use a Metolius brush or a hard tooth brush that has been shaved down and the bristles cut short; any of these alternatives would work just as well as the other.

The following constitutes the sixth step in the process of installing titanium bolts:

When working with epoxy resin, make sure to follow the instructions that were provided by the manufacturer. It is essential to use as much adhesive as possible given that pure epoxy resin frequently becomes as hard, or even harder, than the rock it is placed in. In the majority of instances, I first empty the three full-trigger pulls into a plastic bag that is placed on the ground. After that, I make three test beads on the ground or on the rock in a location that is not specified. Because of this, you will be able to determine the degree to which the glue has hardened when you come back the following day. The guns have an automated puncture system, which means that one of the tubes is typically punctured a fraction of a second before the other. This results in an uneven mix when the gun is first fired, which is why the guns have this system. The going-off process takes place on the inside of the nozzle at varying times determined by the temperature.


The following constitutes the seventh step in the process of installing titanium bolts:

Put the nozzle all the way into the hole so that it can't be removed. If you do not want any air pockets to form, you should only pull back on the nozzle while the resin is being extruded. This will prevent any air pockets from forming. As you move forward with the process, insert the bolt while slowly rotating it in the opposite direction. If you feel any resistance at all, it is most likely an air pocket; the simplest way to solve this problem is to remove the bolt by one to two centimeters and then re-insert it; you may hear a small popping sound when the airlock is broken.)After the excavation is finished, this can be used to fill in the trench and clean up any debris that was left behind. Before I apply glue, I perform a test on this while drilling with a solid gate on the bolt to ensure it will work properly.

Installing titanium bolts is currently at the tenth step of the process.

In spite of the fact that the glue should be fully cured in just 12 hours, you should still wait at least 24 hours before loading the container. This is true even if you live in a hot climate. The test beads that you created prior to applying the glue can be useful in this stage of the process. The bolts are considered satisfactory if they are able to pass this test. Some of his all-time favorite crags are located in the state of California and include Pembroke, Taipan Wall, and the Needles. In the United Kingdom, Thailand, Australia, China, and India, he is responsible for the establishment of a large number of routes, both traditional and sport. At this time, he is working on rebolting existing routes and developing new routes in Thailand and Costa Blanca, both of which are climbing destinations.
