wow. do you suppose he was going to install a bat-house? seriously, are they going to use that tree for a spar or what? why is he topping it, maybe to prevent the log from splitting?
36 springboards to where he started setting doubles. at 2.5 feet per = 90 feet. + 15 for the platforms = 105' Man, thars a big tree.
if it takes 2 or 3 minutes to chop, haul up, and set a springboard, thats an hour and a half or more likely 2 hours to get up to platform height. then 15 or 20 minutes per platform, another hour. that seems fast, maybe a 10 minute rest every hour or so, 3.5 hours to get set to start working!
He will probably have to set a platform around the whole backside of the tree to cut it + lunch, so another 1.5 hours.
then a 1/2 hour to top it, an hour to get down and remove all of the spring boards.
then an hour to fall the pole.
= 7.5 hours +packin all those boards in and out. I'm guessing they worked in 2 man teams?
anyway does that sound reasonable? a two man crew could do one of those trees per day?
What do you suppose their accident rate was? 1 in 500 workers dead I'll bet.
