First rigging block help

honestly, i like small sized stuff, and if you know your not going into huge weights and creating large forces, i love the DMM pinto pulleys for rigging, or the omni block which everyone loves.
but if your committed to to block idea, i cant imagine every needing something bigger than that green ISC block for a half inch line. and its small enough and light enough you could probably easily create something you could set and retrieve remotely with the XRRs.
i just talked myself into wanting one for myself

So I have a bunch of X-Ring configurations but figure I should probably own at least 1 rigging block, just because. I really only do light rigging in fact I don't even own any cord larger than 1/2". My 2 thoughts are either the new, ISC Green block or the new ESA Gold block. Any thoughts on either one and is it okay to run 1/2" in the ESA that is made for 3/4".

Wanna trade some xrings for a cmi 5/8 block .? It loves the job!
 
I had the ISC block that TL featured first then went to the DMM small block. Both are good though I personally think the DMM more robust. Given the two you've selected, it really comes down to the maximum loads you'll be putting on it. From what you've described the ESA seems like overkill. And yes, you can run 1/2" in it.
 
I have no doubt those DMM blocks are probably the best out there. But they're so damn expensive. Since I have no problems with the blocks I have (all ISC - 1/2" & 5/8") I just figure I'll use that $ elsewhere on a necessity. But yeah, I've always wanted one of those DMM's.

I do have an old steel 3/4" block that I haven't used in forever. Not too 'finger friendly' in the tree. I've dropped the threaded bolt so many times. And heavy? Man that thing feels like an MS660 hanging off your saddle. It still has the old National Arborist Association sticker on it.

I had one like your talking about minus the sticker and that large dmm is amazing ,I love the hollow spindle,! worth the extra dough just for that feature for me , let alone its bombproof. Heavy though ,but what do you want for 60kn wll. We call it the terminator! Lol

If you want your ropes to last, it's important to match hardware to rope diameter. Sampson Rope recommends that the sheave groove be slightly wider than the rope. If the pulley groove is too wide, the rope will get flattened under load, and that will put greater tensile stresses on the topside fibers.

That's interesting and I was unaware of that. Thanks.
Considering though all the natural crotch rigging we've done through the years I'm not too worried about that. I'm guessing Samson isn't speaking directly to the arb industry when stating that but iDK. I think we tend to go through ropes a lot faster than other industries. I'd be much more worried about using too large of a rope in a sheave not designed for it.
But again thanks for that info. Not trying to be contrary. I just get scared of trying to save a rigging rope for too long.
 
Another thing to add is that most of what we purchase (block/rope combo) is laid out pretty descriptively and explained well by our suppliers. Good reason to buy from a reputable tree care supplier.

All the blocks work well ,, I have grown a dislike for the aluminum with spring release after some time or maybe heavy loading they are a pain to work properly
My blocks of choice are the stainless cmi ,,,,cheap and stong as hell also screw release captured bushing ,,,I believe the dmm are captured as well,,, dmm's are heavy but the big one is on my list,,so many things possible with it
 
I was thinking Aluminum just because they looked a little more rope friendly. Being my first block I figured rope friendly might be a good thing.
 
Theoretically you don't want to get 1/2 inch block for 1/2 line (cycles to failure)
What's getting the most work ? The block and sling so a littil larger makes scence for longevity

Do you have a spending limit monkey ? I would consider that if I was you and what your looking to achieve with the block that you can't with the Xring configuration s you have . Because the rings are very rope friendly from less than desirable rigging scenarios,being round. If $ isn't an issue any of the aluminum blocks are more rope friendly than the cmi's . From my point of view all companies that make blocks seem to have good quality. Really the little details set them apart. You, by the sounds of it you know what your looking for,just working out the details . Id look at those xring configuration s again before blowing a load on a block. Literally.
 
I don't know that I actually need one, haven't yet. It's more just a thought that I should own at least one. Maybe I'm wrong now that the rings are out, does anybody else rig off of rings only?
 
Even X will tell you rings are not a replacement for blocks. Of course I think he also said he hasn't used a block in awhile. :)
You gotta have at least one block ML. I vote for the one above.
