Handbuilt Ascender

Been here much more than a while

This has been on my mind for well over a year now. It seems that every time I reach for my dual handled ascender before a climb, I wish it was smaller. Truthfully, I'd be much more likely to bring it with me more often if it was smaller. That always got me to thinking that it should be foldable without losing any function. I always a fan of gear that can do it all in a small, well designed package. I'm happy to see more and more gear nowadays that fits that mold for us tree people.

This build was specifically done with the Stationary Rope Work Position climber in mind. It was not designed to be tethered to, nor as life-support. It was simply built as an aid for those that may fatigue their hands over time due to ascending lower diameter ropes. A SRWP climber can often encounter a scenario when close to a spar or stem and Rope Walking is not practical. This ascender will work well when coupled with a foot ascender in such a case, and especially well when installing a temporary RADS (3:1 haul-back) for extended high angle limb walks.

This ascender was built from a scrap piece of 1/4" aluminum plate, a broken pallet slat, old throw line, a broken spring, and salvaged hardware...all of which has been waiting patiently in my shop to be reused for considerable time. All shape was created by welding, grinding, and smoothing with a flap disk. This includes the cam, which used a Petzl cam as a template for shape only. Drilling and countersinking was done with a battery powered drill, and the wooden handles were rough cut with a jig saw. It was built without a drawing, and I will admit it went together more like free form sculpture than machined, but I'm ultimately happy with the end result.

While this unit is crude at best, it is completely functional and effective, and it represents something that I would hope to see on the near horizon from gear manufacturers.

That thing is sweet! good job. Next you will be making a integrated pulley for the 3:1 function.
Thanks, Evo! An integrated pulley would be slick for sure. The biner will have to do for now. I think I've inhaled far too much aluminum dust for one lifetime...or at least for this week! LOL! I'm sure I'll think of ways to improve it after flying it for a while, but that's exactly why I made it. Hopefully any further ideas don't require a 3-D printer to realize.
 
Awesome brother. We were talking about that a while ago. Nice to see the product. Looks good, gonna havta get one of those
Thanks, bro. I just hope this thing holds up for now. If it breaks, I'll send it to you. LOL!
 
I'm sure if you shop around you can find some aluminum stock close enough to the dimensions you are wanting. That would take a lot of the grinding/welding out of the equation.
 
Looks great. If you want to save some work I have have a suggestion. If you can work out the handle and just leave the end plain you might be able to affix a foot ascender to it. Similar to spurscender.
 
That is a really cool design. Something like that fine tuned would probably replace my Futura. Great work
Appreciate that, Mike. That's what the aim was. I had a Futura for a hot minute, but I let it go as I got more into SRWP and wanted two hands on acsent. It definitely needs refinement but just how is the question. I imagine not leaving the ground without it if it even now, never mind if it was more trick.

That was thought, but I took on the idea this way more as a challenge under inspiration.

What I really wanted to do was have a large hollow hinge at the very bottom, large enough that both handles are connected by straddling the main frame for stability, but a carabiner could fit through the hinge hole. This way, the handles would stow up the sides and stay in the same plane as the cam.

Maybe I'll get SUPER inspired and start building the next one this weekend! LOL!
