WoodlandTC - I was there for 3 days although I couldn't do anything until after 10am when Steve and co turned up so they were short days, small sections.

Great idea cutting a natural crotch to rope off, but I think when I try it I'll place the crotch to the side being pulled to so any chance of the rope rolling around to the other side, slipping off, and running on the lanyard and/or climber will be eliminated. Cool trick, for sure!
[/ QUOTE ] Excuse me if I'm being stupid Butch but Ive just had a drink staight after work so I'm not all there right now. the way I'm reading what you're suggesting is exactly what I thought I'd done i.e. the portowrap laghooks and crotch were all to my right to ensure the chunks to fall that way....what an I missing?
[ QUOTE ]
How many lag bolts do you usually like to use, total? Do the groundies remove them and send them back up, straightaways - rotating two sets? Or do you have a BUNCH of them and just collect them later?

Ive never had to use them before. Those sections couldn't be afforded any drop because of the stuff underneath and the so the crotch idea was all I could come up with.
I’ve picked up some heavy stuff with single lags just to see how they'd hold but wasn't 100% sure on how smoothly the chunks were going to fold over the edge at first but as it was they went fine. I put four in anyway and doubled the slings over to make sure, as I knew if one were to come out it would have gone straight through the roof underneath.
I had plenty of spare lags up there but they come out much easier than they go in so I had them back in a minute or two and besides, I decided to carry on with the same ones just to see how they stood up to the work....one was a little bent but other than that they were in tact.

And what's up with the bulky tools (blockdriver?) for those little chunks? I woulda simply pushed them off. It seems like the trade-off between packing that around and just pushing ain't worth it, eh?

Well, its probably hard to tell on the video but I had to come in from both sides with the 088/36in bar so they were still 4 ft across and over 200kg. I wasn't really stood on that stump, more like hanging under it so leverage, or lack of it would have been an extra problem that I could do without, so why not add 15 times my own strength to the situation!
The Blockdriver just sits on top till I need it so its not in the way really. I borrowed that 88 for the day and even though the chain was new, on its side it cuts just aweful....great and true heading downwards but put it on its side and it starts a new cut every time you try to move it round, so you end up with a terrible surface finish, ridges every where. so those sections needed to be raised and kept that way on their journey otherwise they wouldn't have gone anywhere, or worse, they might have swiveled in the wrong direction. I didn't like the thought of being ripped down the spar so I used everything I had to make things favorable.

Sweet trick with the rope retrieval, but why was the pulley necessary? Couldn't a simple large eyed bowline done the same? Just curious...
[/ QUOTE ]
That sling wasn't quite long enough so the guys were actually pulling against it to get the branches clear from the building etc, so in this instance a bowline would have just bit into the lowering rope and made things harder.
