    Components of a Self-Advancing Knee Ascender (SAKA)

    Skin, clothing, and most importantly harness webbing and other load-bearing textiles. There are ways to work around this but I prefer a bungee that is inherently low friction.

    Throw line/ throw weight thread

    Do the additional weights that are clipped on rather than thrown need to be actual throwballs or could they be something cheaper and less durable, like a square of cloth and some shot with a string tied around it?

    Trying out my mini-wrench hook combo

    It looks like you are using an Ultra O on the line you are carabiner choking. What is your reason for using that rather than a PerfectO?

    Components of a Self-Advancing Knee Ascender (SAKA)

    Would you ever use the SAKA without also using a foot ascender?

    Components of a Self-Advancing Knee Ascender (SAKA)

    My choice to post in this thread has caused a lot of confusion. I am not putting a bungee in a tube and I am not trying to DIY a SAKA. I want a durable high-stretch non-abrasive bungee cord to advance the floating foot ascender that I already own. Shock cord from REI is stretchy enough but...

    Components of a Self-Advancing Knee Ascender (SAKA)

    @ARLO If I ever need a true knee ascender I'll keep this in mind. I am a beginning rec climber and I just need to float a foot ascender because I don't wear boots. @Aerial Traveler I bought Robline 4mm Dyneema shock cord but it doesn't have enough stretch. Would you measure the actual...

    A bit more complicated than that? Iowa Code 535.2 " Except as provided in subsection 2, the rate of interest shall be five cents on the hundred by the year in the following cases, unless the parties shall agree in writing for the payment of interest at a rate not exceeding the rate permitted...

    Vacuum cannon for line launching?

    Boy I feel dumb. I forgot about the line itself. I can't see how that could fit into this. This is like the functional hybrid of a Big Shot and a classic spud gun. Could it work for line launching? If shots are made upward it should be possible to brace the cannon on the ground. The...

    The original video has been pulled. What brand of Dyneema bungee cord was recommended?

    Do they sign that in advance? A lot of people don't read the fine print I suppose.

    Sticht Hitch

    I stuffed a bit of scrap wood into the hitch in the place I envision my friction bar going. As I did not contour it to fit the ring it sticks out a 1/4" and no part of it sits inside the ring so there's no room to carve a groove. Does this clarify anything?

    Sticht Hitch

    Not the way I am imagining it with the v-groove in the middle of the ring. Maybe I misunderstand, or maybe I cannot communicate well. I'll try to make a mock up and take a photo.

    Sticht Hitch

    Okay, if the goal is a complete transfer this is clearly not suitable. I see value in something that is able to descend a tight line without having to "down Prusik" so maybe this is worth parallel development. If you choose not to pursue it I may. What do you mean by "it would extend the...

    Have a bit of a problem with arbpro bags

    Manufacturing defect in my opinion. I would see if they will replace it.

    Sticht Hitch

    I am lost here. Is it not the case that extended descending on the original Sticht Hitch configuration puts too much heat and wear into the upper wraps, which is why there are all of these alternative ways and places to add friction including the one you just showed in #338? Do you mean my...

    Sticht Hitch

    That's a nice compact way to allow direct control of friction from the lower part rather than the cord wraps. Downsides: It looks complicated to manufacture. It requires enough slack in the rope to lift it across that groove. It looks like it would add friction to hand-tending? I wrote that...

    Sticht Hitch

    I agree that a lot could depend on the rope. Even Pit Rope bends in a brake bar rack and I don't think anyone would be using something that stiff so rather than the bending itself I am more concerned with how squish-able the rope cross-section is. If it cannot be pressed fairly deeply into the...

    Sticht Hitch

    @Brocky Thanks for sharing more of your designs and experiments. Select replies. In contrast to both the carabiner brake bar and #333 I am not proposing passing the rope behind or around the bar. Further the long axis of the bar would not be transverse to the rope, instead it would be parallel...
