Controlled free-fall (vertical speed line)

Stood at about 50ft and totally shot at tension side of the butt, we weren’t so much worried about the ground impact of the falling logs....more them flying into the fencing there after. Plus the tree was a leaner so I didn’t fancy trying to wrestle back the logs up top while further hoping they’d stay put upon landing, hence the VsL
.
The lowering device was in place to make it easy to tie/tension and untie the rigging line....although I would have much preferred a redirect but there was nothing near to otherwise anchor the lowering device to.

The Stein 2000 LD is built tough, but I was still a little concerned about its attachment-sling getting wacked by a log; thankfully we got away with it this time.
I used two tennex slings to tie off each log which were linked to the rigging line by a D-shackle.

The orange ratchet strap set at the base of the tree was to stop the shackle hitting the Lowering device.

The last 15 ft was absolutely riddled with metal, the worst I’ve ever had to deal with.

Just a short vid this one. Thanks

When I see the postage stamp spaces that you guys work in I get claustrophobic!

Nice job and fun vid!

I feel the same way Tom. They have some tricky sites to deal with.

Awesome job as usual Reg!
 
Thanks alot.

You're right Norm, that might have been a better option but I didn't have one with me on the day. The two logs placed in front of the LD did offer a little protection also.
 
Reg, it looked like the LD stood up just fine to the rigging.

Did you find that the tires helped a lot with the impacts, or could you have gotten away without them. I've been storing up tires like that for the day that I need them, but so far brush and logs have worked out OK. Just curious what you thought.
 
Well Reg I am starting to think you loft must be tight cause you like working in close quarters. Another good vid, and was that just a normal biner or what rate was it? How does your rope handle the speed ? Was watching Acemasters speed line vid and your vid to get ideas was just wondering about the tools and how they held up. Again good vid and nice job, like the slow mo of the impacts.
 
Chris, tyres are good for softening an impact in that they don’t break apart when they get hit, and even better when you tie a bunch of them together. Down side is that they can propel light logs back up in the air, and you have to leave room on the truck to take them home at the end of the day. On that particular job the chipper had gone already and we didn’t really want to be throwing lots of broken brush on the truck....so we used a brush/tyre combo.

Tarporing, I was using a d-shackle not a biner. The speed wouldn’t hurt the rope at only a 30 degree lean as was the case here, but you have to consider more how and where the rope is tied off at the base which obviously has some bearing on how severe a jolt is gonna occur on impact.

Easy, yes it was a black poplar, you'd most likely call it a cotton wood.

Thanks again
 
Nice plan and Nice execution. It looked like a lot of fun. Except getting that big wood out of there

. How did you get it out? Great Vid.

Nice job, an old as dirt style, but still good work, nice to know some of the young guys know what to do.

Ed, I'm probably not as young as you think, perhaps theres only a couple of years between us. And there are plenty 'Old' guys out there who've been at it forever, yet are still clueless.

FSquirrel, we just cut and carried etc, but the metal was a real sickener....every cut of the last 15ft!
 
Reg, did you guys go through a lot of chains on that last 15' of wood with all the metal in it?

When you say you carried the wood, did you guys actually have to carry it by hand, or did you have some kind of dolly or wheelbarrow to load and carry it out?

The metal thing was frustrating Chris. I think 2 chains were totaled while the other 2 are now down to their last quater.

We did have a barrow but some were too big to fit in because we couldn't get the saw through. Thanks

Nice one once again Reg!

I like the slo-mo impact shots.

Must be a bit warmer over there at the moment!
