Yes I did :D...When I was going to bed I realized I'd gotten sidetracked and forgot what the point of calculating the angle was, it was to show that less rope contact around the branch equals less friction so more force at the TIP. The example off the top of my head was a limbwalk but yeah that...

No worries :) Yes I agree that friction most definitely matters. If I run a few different friction coefficients (guesstimates and ballpark #'s I remember off the top of my head) through the scenario I originally posted, 0.5 for a natural crotch (IIRC I saw once 0.4-0.6 for rope on wood), 0.2...

Fair enough. I don't have a horse in this race (retired from tree work 10 yrs) so 10 seconds calculator time and $0.0001 in pencil lead is good enough for a forum post :). Just thought it was interesting that the math, conceptually at least, correlated with Levi's experience. FWIW, the...

Just doing a back of the napkin calculation here with some assumptions I found a 200 lb climber with a base tie going over a natural crotch would result in roughly 42 lbf of tension on the opposite leg of rope. So a little more force at the TIP than DdRT or a canopy anchor but well less than the...
