Thanks for the comments everyone

Did the video start at the first branches or had you already been stripping it for a while?

already been stripping lower stuff for a while, it was branched to ground level, I just thought it'd be too boring to show that stuff in a vid. The speed/zip line worked better than we thought it would, saved some time and effort, only ever use it though when the tree and jobsite is just right.
 
Nice Grover, but a few tips for ya if you don't mind...

Send down a bouquet...with small branches like that, I'd be slinging 3-8 and sending them all down as one turn. Far faster and more efficient.

Or, if there's no real need for a control line, send them without..that too is faster.
 
Roger- If I picked it up right, that was more of a haul back line that control line.

Grover, Good vid and music. I'm with Roger. I typically use non-locking cheap oval biners directly on the slideline, I've lost one, maybe two. If you send bouquets, sometimes it snags up with a sling flipping over the slideline, but individually sent, tensioning once per whorl , works great. If something looks worrisome, then I'll use a locking 'biner. The wear is minor compared to the production.

Dropping small blocks directly on the slideline of a strong tree doesn't seem to be too big of a deal. I have used a crash pad of brush to land the blocks to avoid lawn damage and groundie damage.

You might have been able to use a vertical speedline with some plywood on the fence rather that catching each piece and lowering. That avoids all the moving of the block down the spar.

I've been trying to figure a good way to anchor the bottom end of the rope rather than having a pulley down low to redirect the rope to a friction device, but haven't come up with anything great. Maybe a dedicated figure 8 with a screw link to a large eye-lagbolt right at the base of the tree. Anybody have any ideas on this.

Keep up the smooth work Grover and the videos.

good points, thanks for posting them, I havent yet worked out a system I like for a vertical speedline, when I do I'll post a vid of it.
 
I'm dreaming up a retire-on-it master product for anchoring the bottom end of the speedline that will be perfect for not worrying about smashing a lowering device. I won't say anything more now. It will work for solo rigging up above as well, so the climber can tension from that end when there is not a lot of limbs to send down, like a 2-3 whorl canopy raise, allowing the groundie to keep processing the brush.

You'll see a video soon, but it will likely have a black bar across the secret product.

You'll can visit me at my retirement island in the Bahamas. Drinks with little umbrellas on me.

The real challenge is getting a good rope-bend radius. I'd thought about a garda hitch/ garda heart attached to a lag bolt. Maybe this will work with two shackles in place of 'biners. I'll have to experiement. Shackles could take a blow from a big chunk bouncing back into them.
