One problem I’ve had with my harness traces is loading shock to my back. I’ve tried a loop and drop method like this.
Whereas in the below video I show a harness trace design that doesn’t put a static line shock into my back. This method is much nicer because the bungee almost completely prevents the line from ever becoming taut, the source of the shock.
When I’m towing my tire on a surface with a large drag force, above about 30lbs, having a bungee in the trace line is actually annoying no matter what. The tire doesn’t slide at all, so with a smooth walking or skiing motion, there’s never any read shock. But in the 5-25 pound drag force realm, where I expect to be in Antarctica, the sled or tire slides forward with my motion all the time, causing this problem.
With really heavy bungee, this seems to work quite well. Also, another bonus is the line
and bungee don’t get snagged on anything, as they’re not dangling as in the above photo. I definitely prefer this coiled trace harness bungee line method.
This is now my preferred method for reducing shock in a tow line.
I have bolted the straps from one of my sponsors, snowsled.com, to my Paris sleds. These straps prevent the entire bag from sliding out of the sled in case I tip it over or in the worst case, the sled falls through crevasse.
If my sled were to fall through crevasse and take all my gear with it, I would be in major trouble.
So, with a few straps bolted to the sled, this thing would be dangling in space. Hopefully it wouldn’t take me with it, though. But, since I have two sleds, that is hopefully less likely.
I am working on my final food preparations prior to shipment via air down to Chile. I am trying to figure out how to pack 90 days of food into the sled so I still have some room for something.
90 bags is sure going to be a lot of space. Having everything pulverized & mashed into smaller space would definitely be better. Also, I am trying to figure out why my bag of simulated food weighs way more than my food weight estimate. Either the packaging lies on some items or I miscalculated. I will figure this out quite immediately.
