Ahh well, I know it can be bad in some ways but its pretty cool going out there and flexing your knowledge of a 5:1. Its just that we can't let them think it comes real cheap and easy.

Goodaking, To bad your thread got derailed. I used the fiddle block for a couple of years before we got the GRCS. I've always referred to it as a poor mans GRCS. It is a good tool to have in the arsenal and once you find its value you will step up to the real deal. That said, start with the fiddle block, you won't regret it. We still use ours for different applications. Pete
Newb (omg! you are from WI too!) How are you attaching the fiddle block to the lowering line? We have a 5:1 that we attach with an eye and eye split tail and we have a 3:1 that we attach with a Micrograb. I am concerned about using the Micro because I fear damaging the rope with it..... thoughts from anyone...... even those of you from CT.

The rope grab can damage the rope. However, we use two fiddle blocks with rope grabs and so far have not noticed any damage to the bull ropes used. (in years past there was damage for sure over time.. could be just that the rope composition is different)

Emr, You would have your porty set up for lowering, if you need to lift a branch, set the fiddle block up for lifting (hooked to the porty and a prussik on the line) after the lift you would need to remove the prussik. Alot more work than the GRCS, but works. I don't think I would ever use a cam devise for rigging. Pete
i all ways try to show for final tweak/ tighten can take a 5:1 and get 5xBodyWeight + 8xEffort by a 2nd hand pull to other side of fisrt pulley by hand pull. the formulae is the body weight can pull on the sys, plus effort 2xJig - 2. the minus 2 is for the 2 legs of pull you lose skipping the first pulley with 2nd hand pull. the 2x is 1xEffort + 1xEqual and Opposite of Effort! Insetting 1 jig inside another in like fashion, does similair.
Stihl, if that is you in that pic at the bottom of your posts.....I am very sorry. I was just pulling your chain. Do all tree guys in CT look like you? My god, I am glad that my competition is not built like you.
They arent actually that tight though it does appear so. Its the #### saddle with 1" straps.
Oh yeah the huge pair of twins between the straps probably make them look tighter then they are

:hmm3grin2orange:
An old expression from tree trimming many years ago was "You know your tree is properly pruned when you can throw a cat through it, and still get it out the other side".
I imagine that the dead cat expression is somehow related to that old phrase.
They told me that too and still do. Until they see me climb. Then its "you sure that limb will hold you".
