First rigging block help

I'm looking to hook up

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.

I believe antal rings configured correctly can handle any thing a block can . That's why sailing teams use them.. to replace blocks ..less to go wrong..they call them sheaveless blocks. From an arb standpoint under certain conditions a block may be better..maybe somebody can provide an adequate reason ..but I don't feel like its anything that cannot be overcome with a change of thought or some other variable in the rigging scenario. I have blocks and they just don't come out of the bag because I now have xrings and may not have blocks if I knew more about rings when I was buying blocks.. I'm learning and thinking about things of the nature everyday. Even for lifting stuff now I've recently had a change of thought myself that's led me to seeing the xrings as the complete package for my rigging needs. Really..even if I destroy some during dirty operations they're cheaper to replace and there's less to go wrong.. no moving parts.. light as shit. Bomber dude$! Why do you need a block , seriously? Think outside the box or the block if you will. Maybe for giant trees ,but I think its more a sling swl issue after a certain point
.. But who am I anyway , this is coming from a guy who didn't have anything ,or feel like I needed anything at the time ..but a rope to dismantle trees for a few years before being introduced to a" false crotch"back in '99. That said ,block me right out !:robotbox:

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

Ionly?

I have six or eight nice blocks, three or four that fit your general interest, two exactly. I use them rarely for long pulls or longer heavy lifts. Almost all XRR for me.

Maybe I should long term loan you one of mine.... Good news for the arb supply company is that you love gear...just like me. Buy exactly the block you want, the inspirational factor alone will be worth it.
 
I do love tools, being a toolmaker. Ask my wife, she'll tell you I own more stuff then 10 people should own lol. But she knows that being a craftsman I use and love everything I own, and everything I own has a purpose.
 
I bought a yellow aluminum isc 3/4" spring block 7 years ago and have went through 4 or 5 loopies that go with it through out that period of time. it has put down more trees and picked up more storm damage from houses than i'd like to count but over those seven years(3 of which i was a contract climber with my own rigging gear and all i did was nasty removals with the occasional huge prune). for the small investment it has made me $1mil gross as of this year. I use 1/2" lines in it, 5/8" lines in it, and 3/4" lines in it. I own 7/8" bull line and a 1" hobbs block for the big stuff. I am thinking about sling diameters now though and ways to cut stuff smaller and yet be as efficient (my guys love to work large material into a tight hole). I have broken ropes(pulling logs out of ditches), rigging points (lifting storm damage), and rigging slings(over rigged on an old sling with no run for the goundie). No one died or no house got leveled as redundant rigging is your friend. Mark did a work shop down here this fall and told me to try double whip tackle when blocking down a huge tree. i haven't had the chance yet to try it, but an xrr sling is going into the rigging bag for this purpose
 
Santa brought me the ISC Red 1/2" block and the Sterling BARC so that is what I will be using until I need to go bigger. Already have plenty of other anchoring options if I find I need more than the BARC.
 
I havent used a block for anything other than lifting or straight up negative blocking since I got my first XRRs. That being said ML, you got a good one!

Those ISC blocks are nice, and a good value, no two ways about it. You will get a lifetime of use out of it.
 
XRRs kick ass for vertical speedlines. One tied to the piece being rigged and one as a redirect at the bottom so the porty doesn't get smashed. But, to stay on track with this thread, I've been loving the value and robust yet compact qualities of the ESR block from Treestuff.com.
 
Once the stainless CMIs came with a captured bushing they became our default.

Have bought over 20 of 'em. 15-16 still exist on the trucks.

I only wish they had a tether point like the more expensive blocks have.

The ESA blocks might be a little more compact and have some more bang for your buck.

Yes, it's a nice tight package sharing the best qualities of both the DMM and ISC blocks (smooth rounded rope friendly forging, simple quick spring lock function, and small easy to hang on the saddle tether).
 
Gotta have a block for storm work. Lifting something in normal work, too, be it with a GRCS, Fiddle Blocks, or right-pedal power.

Rings will magnify the force on the rigging point beyond that of a block when you are trying to lift. Friction is 24/7. You gain by using the friction to your advantage, and lose when it fights you.

Supposing you have 80% efficiency for rings, static loading and lowering a 1000 pound piece would put 1800 pounds of force on the rigging sling/ rigging point in a 180* rope bend scenario where you would have two parellel forces (ignore the 80/1800/ 180* thing possibly sounding related).

Lifting a fully detatched piece would put 2200 pounds of force, all else being equal, to my estimation. If you are just standing something up from partially horizontal to vertical, you aren't lifting the whole mass, just rotating it, so your force to lift/ rotate to vertical will be much less than the 1800 pounds generated, provided you are tied at a decent distance from your hinge, as is typical.

Hopefully you're not working so close to your limit that this will matter often.
 
Some of this makes sense to me . Some its hard to make certain with hard evidence, without some deep study possibly.I don't know.
Magnifing force on anchor point . Does olds magnify force because it provides some friction? I know in lifting more force may need to be exerted on an anchor point with less effenciency , but how much more force is really stressing the anchor point.. pretend there's no device in the tree and your lifting with a rope directly over a crotch . Will that exert much more force if the load hasn't changed?Definitely over a natural crotch losing quite a bit through friction, but I think ,and I may be wrong . its rather marginal when comparing rigging rings to a blocks. Please somebody straighten me out . I need some help with this thought. Like stated above we try to stay within safe working parameters , although working with truly unknown anchor points all the time , just having gained trust of them through faith and knowledge and experience. Gotta love treework!
