Since I'm a real gearhead I have a singing rock full body harness, that fits meAugie wrote:Thanks for that analysis Matt. Lots of things to think about for a drop like you're planning. As far as full body harness, would it work to use your regular waist harness and a make-shift webbing chest harness or do you need something more elaborate?
I can add some friction by making a z rig to the biner on my leg loop and back up to the tie off bar, your kinda committed to this rig for the duration, or at least that's my experience in the past.Augie wrote:Sounds like you need tremendous arm strength to pull up for slowing with your device. Also sounds very iffy if adding friction during this long of a rappel would be "nearly impossible." This alone would make me rethink.
I can in a pinch add friction by putting the rope around my back, but that's a last ditch effort . Don't wanna get there
endless, most people experienced in these types of raps recommend a rack though, one huge advantage is it doesn't twist the rope.Augie wrote:What other options are there for a rap device besides your bar rack?
I have many, many, many different rappel devices to choose from except a self-braking variety which to my knowledge wouldn't work with my 8.5mm rope anyway
Just looking at various web resources for J-Bar racks they are not designed for 8.5 mm ropes. NFPA rack that I have I can't find any spec's on it but I would be surprised to see specializations like 10-13mm dia ropes
I have a 350ft 11mm rope I've used like 5 times, canyoneeing with 11mm rope S&$ks
So that may well be part of the problem
