Sorry. Near Bristol or maybe Midlands. Apparently, somewhere along the M4. Any takers?

Hello, I am wondering if anyone in the Southern part of the UK needs a good hand. One of my guys is leaving for your side of the world. He loves tree work, is bright, an extremely hard worker. He has been exposed to some good tree work, I would like to know he is working for a good outfit. Does anyone have any suggestions?

My favorite still (1 is 21 years old) is a Gibbs. Going to test the SMC grab they make for PMI, but the old standby has serviced quite well.

I'm trying to decipher the model from the sticker on the inside. I think it's a Kask srl Plasma work model. What a surprise, ANSI would require a soft helmet material. I'll be doing strike tests on this helmet over the weekend, we'll see then what pro there is from the side. It is the most comfortable helmet I have put on in 23 years. I'm just not sure if that's a good thing.

It's the double braid Yale should push for tree rigging. Double Esterlon has a poly core, not much energy is absorbed. Polydyne is their double braid, same jacket, just has a nylon core with much better energy dampening. I prefer Polydyne when Negative blocking ( Square rigging).

Steve, if I am negative blocking, or even using a block with a high advantage, I prefer the Polydyne from Yale. It has more ability to absorb energy created. The Double Esterlon is too static, it's great for lifting loads, but not optimum for rigging scenarios that compound force.

This helmet is nice and light. Fits well too. The head band looks like the stuff on the inside of my climbing shoes, which makes me think it will smell similar and develop a nice funk on my forehead. I have had a couple of bad concussions, allegedly, I cannot take too many more, therefore I opt for the highest level of pro I can get disregarding weight to a degree.

I am currently testing a Kask helmet for Wesspur. I am curious what features do folks look for in a helmet. For me, protecting the little bit of functioning gray matter I have left is very critical. I feel the Kask falls way short in this regard, there is 0 side impact protection, the shell is much to soft. I would guess many folks will like the features that allow a visor, and muffs. I do like the retainer clips for a headlamp. Having the styrofoam in the top, blocking airflow over the top of ones skull seems like that will get overly warm. Overall it falls short for me. I would allow any of my crew to wear one on the job site. Still, I think the Pacific kevlar helmets offer the highest protection.

A very easy power gain can come by opening the exhaust port up on the muffler, adding an aftermarket filter like a Maxflow. Remember it is important to richen the high jet when this is done. The limit caps will need to be moved so you can increase fuel on the high end. this simple action will give a marked increase in performance.

I've been chewing on it some Pete. I'm a bit touched by the numbers in that study and how they are vastly different from many quoted stats here in the US. I thought i was playing safe telling folks that a knot can negate 35% of tensile strength. I would like to see a test like that done with High Modulus fibers. My own experience has been enlightening.

Angus or Graeme, I have a question. When I do this it's always with much lighter weights, or very small angles. In the work situation you were in, there was opportunity for a large increase in force on one rope as that line angle becane greater. When moving blocks around, the angle on one high block would be around 70 degrees? maybe more, the angle on the "close" block would be less than 45 degrees. Is the the extra force imparted on the far block negated by the higher capacity gained as the angle decreases on the "near" block, or does the far block and line bear more force?

I have been training crews for the last 7 years. In this region the most common scenario is one that requires Negative blocking. A porty, 9/16" x300' double braid, and a 5/8" sheave block are standard kit. If the opportunity arises to use a high angle block, then the GRCS will get used for sure, Speedlining, Drift lining(pendulum), High pick, crane, are worked as the need arises. For most jobs it is a negative line angle show.

Angus, I have a question. At some point the inside angle on an anchor will be in creasing, as the opposite side it is decreasing, how do you account for the added force being imparted on the far high angle block? Secondly is your program available for others?

I've been pleased with mine.Welcome | Benchmade

Hello. My resolution this year was to participate on this forum. Good, I've knocked that off, now back to my whiskey.
