Dr. Cornwallis's Work Thread And Stuff

The Sugi definitely looks bad a$$, and quality wise they are. I imagine the Sugi will outlast the ES at least 3:1. The SS gives it much better wear resistance at the cost of a bit more weight. The Sugi looks bad a$$ .... oops, I already said that.
That's a proud lil' man holdin that big Sthil, @hsell

I didn't Weight them, but it didn't seem to me like the Sugi Lights I had were that much lighter than the Stihl ES in 28": maybe I'm mistaken.

There is a big difference between the Oregon RW & Regular Weight, but at the cost of stiffness.

I was concerned I would trash The Oregon.

To me, the ES Lights are the best blend of both Light Weight, & Stiffness.

Over on OPE, some of the Members had extra bars & used a lathe to turn a regular weight bar into a Reduced Weight bar: it sounds cheap, but the amount of labor that went into doing a good job more than paid for a Reduced Weight bar.

The outcome was acceptable.




I had just came home last summer from my main job & was loading the truck to go take down a tree: I turned around, & there he was with the next saw!
 
I'm thinking I may need a Rock Exotica unicender. I currently climb SRT using a Texas Climbing System and then switch over to a Rock Exotica micro 8 for repelling and work positioning but the unicender has me pretty intrigued.


Edit: also eyeballing the Petzl RIG which looks like it could replace one of my hand ascenders and function similarly to my current setup, except eliminate having to transition on to the 8.

Thanks guys! I didn't realize any of those options were particularly hard on the rope. I'm checking them all out. Any thoughts on the Petzl RIG? it looks like a nice system, especially when used its conjunction with a pulley. Also, keep in my here in Florida my ascents and descents aren't likely to exceed fifty or sixty feet in most of the time.

A rig is used in a RADS system which is a 3:1 mechanical advantage ascent. I would never climb on a system like that for several reasons.
1) any ascent would take 3x as long as a normal SRT ascent which pretty much null and voids 1/3 the reason we use SRT in the first place( 2nd being the ability to be rescued and 3rd being not having to isolate a crotch).

2) there's more setup and components compared to a RR or BDB ( which I would also recommend thinking about)

3) RADS uses a lot more rope to work compared to a regular system

Speed of ascent was one of my concerns, however it looks like from watching videos people can still make it up pretty quickly and easily, although I can really move with my current setup. Where I feel I lose time is in work positioning.

Having to connect and disconnect an 8 to move around I find very slow, and limiting. The thing that appealed to me about the RIG, RR, and other devices is the ability to not have to tie off when working, i also feel it gives more control when limb walking etc...

The thing I do like about using an 8 is I feel extremely safe on it with it not being a mechanical device.

What do you like to use for work positioning when on SRT?

I use my RopeRunner 100% of the time. That's the beauty of these devices, they're used for ascent, descent and work positioning.
 
Using an 8 for work positioning sounds like a pain. You need something that doesn't need to be locked off to be secure. I've seen a rig used as a work positioning system but they don't function like a multiscender. Any of the aforementioned devices are much more ideal.
 
Wait, I have some input that is contrary to this. RADS does void one of the main reasons SRT is used, but you left out so many advantages that you retain. Redirects!!!!! The ID is very safe (not that the rig is not safe, it just doesn't have all the features) and can be used for work positioning very easily if you have a minimal amount of equipment. I've seen plenty of videos of world-class climbers blasting through the tree on a rig.
And, once you decide to get another device, the rig is great for basal anchor lowering systems, secondary tie ins that you don't have to worry about tangling and making themselves not work, and it is my personal favorite for working down a spar. It stays where you put it and doesn't gobble rope and mess up your choke.

And just to clear his up I was referring to how fast the unicender wears, forcing you to start out with an 11mm rope and work your way up to 13
 
I see it's been a couple months since I've posted here. I have a job booked for Friday but that will be the first largerish pruning and removal job I've done in a while. I've been doing a lot of $100-$200 pruning jobs on smaller oak trees using just my Tacoma, 5x8 trailer and Silky Saw. Not very glorious but I feel pretty happy making $75/hr with virtually no overhead. I line a couple jobs up for the same day and I made my self $500 before noon. I had the same tank of fuel in my MS193 and HT133 for a month. I had to drain the fuel out of my 261 and 661.

This actually got me to thinking I may not need a chipper truck and chipper after all... I feel like I could make a killing off utilizing a 350/3500 sized truck, gooseneck dump and skid steer.

I also ordered a Rock Exotica uniscender and Tree Austria 3.2 to try out. I don't read much about the Tree Austria on here but they got good reviews on treestuff and it looks to be a real quality piece of gear. I really like the buckles on the legs and the waist.

I was playing around with the Uniscender and the Tree Austria 3.2.

To give a reference on the Tree Austria, I'm 6"1 and 235lbs, I hesitantly went with the size medium because I have really large legs and I'm not a medium in much of anything. However, it fits really well with plenty of adjustment, I actually even had to tighten down the legs some. So far it seems extremely comfortable, and that's with minimal adjustment. I think once I really get it dialed in it's going to be even better.

So far I also really like the Uniscender. I understand it wears somewhat quickly, about 18 months of serious use before replacement, however, I climb as a part time job and honestly, if I have to replace a $310 piece of equipment once a year I can live with that, as other than that I absolutely love the design. I've only used it in SRT so far, climbing on Yale Poison Ivy and it's been great. I find the drop you get when initially descending isn't as bad as the internet made it sound.

I believe the Uniscenders can be rebuilt for less money than a new one. Also, you might want to look into the Drum that is made for the uni by yoyoman. He recently posted he had more in stock.

They are, I believe I read somewhere on here it's about $200 to rebuild.

@Dr. Cornwallis if you enjoy staying small with minimal overhead and enjoy that kind of work you do, don't let your mind be locked into the dump truck / chipper combo. It might end up being the way to go, but I think your open mind and creative thinking applied to the way the market is where you are, you might find a better set up to suit what you do.
Keep us updated on your thread!
 
Just a heads up on the RADS, it's actually a 1:1 system if you climb it correctly. The right arm is pulling the rope coming out of the redirect at 3:1, your foot in the footloop and your left arm on the handled ascender (which is the redirect above the Rig) is pulling 1:1. That's how the RADS is climbed. When you're wiggling thru a tight spot or coming back from a limb walk you can pull rope with both arms, then it is a full 3:1. RADS is good for heavier climbers, it's an excellent system to learn SRT on. It doesn't require more rope than any other SRT system. I climb the Runner, BDB, or Rope Wrench but I'll put a new climber on a RADS to get them used to single rope. Then when they're ready for a more efficient ascent they have plenty of choices.

Besides the fact that a RADS doesn't have a straight rope path the main inefficiency is that you can't climb continuously on it, you have to sit back on the rope to move the redirect up before the next pull.
