Block and tackle set

I am about to order a block and tackle set and was looking at both sherrill and wesspur. The one in sherrill is $299 and looks like the one in wesspur for $219. But wesspur also has one for $299, but they call it the large set. Does anyone know how they compare?

Also I am thinking about the GRCS but need more info. I have read about a video with good examples of how to use it and all of its advantages. Does anyone know how to get that video?

Thanks.

My opinion is to skip the fiddle block and go right to the GRCS, if it's in the budget. I have both and don't use the FB now that I have the GRCS. Although, it can't be a bad thing to have both. The GRCS vids are available with a google search or maybe someone has links to them. You could also call and request a dvd from Greg Good.

The only caveat with using the pulleys alone, is that you can't run them vertically, like you can with a fiddleblock set.

Hi cerviarborist - not sure what you mean about "vertically"? You can run the Petzl vertical it's just not as "clean" as the pre-made set, right? or am I missing what the "vertical" is that you are talking about :)

peace,

Hi Matthew, I may not have been clear in what I was trying to say, so I'll let Sherrill say it for me: "The limitations to the tree pulling kit (as sold) are that it doesn’t work in conjunction with a lowering device (Port-a-Wrap)"

(off the same sherrill webpage)

This is what I was talking about. For anchoring onto a porty to lift material, prior to lowering, fiddleblocks have an advantage. I've got fiddleblocks, and wish I had the pulleys as well, but it is nice to be able to put some lift into the equation when needed.
 
But they do! Here's the whole quote:

It's a little miss-leading and tends to steer a person towards the pre-made set (which are very good as well;)

"The limitations to the tree pulling kit (as sold) are that it doesn’t work in conjunction with a lowering device (Port-a-Wrap) if host rigging line is utilized, the system requires above-average rigging knowledge, and it requires a minimum of 30 excess feet of line’s end to make use of. Once learned, this simple mechanical advantage system is hard to forget, and even harder to live without. "

:)
 
Nice pic, Matthew! Thanks for posting.

Now orient it straight up the from a portawrap hitched to the trunk of the tree you're working on, like you can with fiddleblocks Comes in handy if you're short a rigging pulley.

Two separate tools, and each trades off advantages and liabilities. :-)
 
had to bump this because it saved my bacon - rigged and then lifted some large chunks of fir over a cliff. Locked off the portawrap then used a pole and hook to push up the prussik when we needed a bit more. Was in a pinch with gear and then remembered this thread and your picture. Thanks!
 
You can set the double pulleys up vertically, its just a wee bit tough to move them a great distance. However, if you redirect the anchor through a block at the base of the tree, and setup your Port-a wrap some distance away on a second anchor, you can install the pulleys horizontally and lift to your hearts content. Technique is also a good way to add more rope to a rigging system for alleviation of shock load forces.
 
whoa, Zeb. . you're giving away all those secrets those training courses make us pay for. That's a great tip for next time. Thanks!
