As mentioned test the gear at the ground with all your weight on it, or find a steep but short hill just to get the feel of the gear. The figure 8 device is very basic and if you can't figure it out then you shouldn't be doing this type of work. Apparantly you didn't buy the "The Tree Climbers Companion" for only $20 bucks as everybody as mentioned or you would of known how to work the figure 8 device.
Also I believe a lot of rope manufacturers started out making rigging lines for sailboats and the shipping industry, so this guy didn't invent that. Also I would be pretty worried about useing ropes that was used for sailing. Sure in a life and death situation, I'd use it but not for making 35k a year doing tree work. Also if this guy is so wealthy, why is he selling old climbing gear for $200 bucks. If he is that wealthy, I would think he would scared of being sued for selling old tired climbing gear to somebody that doesn't know what he's doing and could get killed. Especially considering in one of your post you said he made the saddle himself.
Hey Legs, friend. I never get tired of reading your posts. Every time I see the orange horizon in your avator, I know I'm getting some well thought out advice on my threads and on everyone elses threads. I missed your post here because I was putting down two posts in a row, and you posted in beween them. I'll look to see if someone posts in between my double posts in the future. You're no waste of time, and your advice is golden. I just missed ya' there.
The guy didn't invent anything but hang glider profiles and airlite products. As far as climbing and rigging goes, he is just another user like us. The saddle there made by Robertson as you can see in the pic was custom designed for the guy I bought it from. Look up Robertson gear sometime. These two guys were working on stuff together for a long time. As I understand it, Robertson made a bunch of sailing gear to begin with, so he could easily have manufactured the climbing saddle for him.
I'm not through the climbers' companion yet. I scanned ahead for the fig 8, but I couldn't find the skinny on that. I did a few searches online, but that didn't get me far. So I was asking here to find out where everyone else is with their 8s except that it's not much fun for some of these climbers.
I didn't buy any rope from this guy, and I'm not worried about rope. He is 64, and he is not selling me rotten ropes, guy. As far as being rich. His divorced wife took care of that. He does OK though.
I would seriously doubt the law suit could land on him for this going going bad. People sell stuff on craigs list everyday, and nobody comes back to suit because of technical difficulties. My gear is fine though.
I'm still look forward to your words of wisdom. I'm repping you if the server lets me do it again this week. I hope you can read as fast as I type. This took me less than 5 minutes to type, soo...
