Good stuff per usual Gord

 

[sawinredneck]

Very nice Gord!

 

[rskybiz]

Nice vid Gord, music included!

I'm curious why the lower pulley was in the system. From my armchair, I couldn't see the reason for it. Was the upper pulley on a questionable limb?

 

[Burnham]

Might have been to fairlead off to a better position for the rope handler to operate.

Nice as usual, Gord.

Riggin 101
ALWAYS use multiple blocks/natural crotches whenever possible.. many benefits.
It changes the vector forces, often improving the wood fibers ability to withstand loading, that is ...the force is changed to pulling straight down the wood grain instead of more perpendicular to the grain.

It significantly reduces the works MA on the a single overhead anchor point, or another way of looking at it is it spreads the same amount of force over two anchor points, significantly reducing the force on a single point, which can get huge with force multipliers/shock loads on heavy bits...

reduces the bend ratio and/or friction/heat on the rope significantly

Creates a system where the flex of the limbs, as they get loaded, significantly reduces shock loads

Allows the climber the flexibility of using either point to rig from either side of the tree.

Allows the climber to lower one of the limbs with a anchor point off the other, without needing to untie the block.

I AM sure Butch and all the seasoned pros here know this already... so the above info is for any newbies reading this thread. Butch's question refers to the reason for using the second block when there was no heavy pieces rigged or shock loading. Its always a good idea to add safety margins to your rigging points, leaving more flexible options to rig out bigger pieces, and one less thing to worry about. The tree looked dead, and maybe he didn't trust the wood. Good thinking, especially if you are tied into the same lead that is being used to rig from. Gives that extra confidence needed to move with greater efficiency, saving a lot more time than it takes to set the extra block up.

NICE vid.

 

[Blinky]

Yep, looks like a fairlead pulley to keep the downhaul and the swinging pieces separated.

Nice video for certain, what species was the one you rigged down?

 

[MasterBlaster]

Short of blocking down a stem, I don't use pulleys for my rigging.

LOL @ "rigging 101" Daniel, you're a card!

 

[canadiantreeman]

Nice work, Gord. Long dead that ol maple, eh?

 

[Gord]

The second pulley was there to distribute the rigging force. I never trust Bigleaf Maple very much, and when it's nice and dead I don't give it any leeway at all.

I've got some more video clips to put together, some of 'crown reduction' (haha) on a leaning old 8' fir and some other stuff. None of the footage turned out too well though.

 

[MasterBlaster]

The second pulley was there to distribute the rigging force.

That's what I thought: I was curious if you had a different reason.

What do they call that sometimes... fishpoleing orrrrr something?

 

[Gord]

I think fishpoling usually refers to multiple pulleys along the length of a limb or off-vertical stem Butch, not too sure.

[TreeDimensional]

Nice!

 

[biggun]

Nice to see a bit of wildlife. Looks like a fantastic place to be working, beats London thats for sure.

 

[MasterBlaster]

Nice footage, in more ways than one!

 

[canadiantreeman]

Very cool, Gord. Lovely place to work.

 

[CurSedVoyce]

Top notch Gord... Beautiful shots of the office mang

Not sure if these are already here

A grand fir removal.

 

[Paul B]

Nice vid Gord. Grand Fir?

 

[sotc]

So did the sling make it in the truck?

 

[woodworkingboy]

+1. Looks like a beautiful day.

 

[CurSedVoyce]

+2 GOAAAAAAAAAAAALLLLLLLLLLLLLLLLLLLLL

One sticky sum biatch Gord. Nice work mang

Really looked like you were pretty much having a nice day of it

 

[MasterBlaster]

Bleagh! I'm glad we don't have those sapsuckers here!

Don't you get nervous blocking down w/o a 2nd tie-in? I sure do, even with a steel core.
