Re: drop a 75\' tree in a 50\' LZ
NOBODY wants to see you go down with the ship, as Evo has shared his personal loss with us, and Blinky shared his personal injury, you can especially see why there is the concern.
Could you have tied to climblines together to achieve the height you needed, perhaps climbing SRT with ground anchor,
or
shot a line and installed a rope with a running bowline in the neighboring tree, with the throwline re-attached to the RB loop, in order to pull it loose and back out of the tree without even having to go to the TIP for retrieval?
I don't know squat about ash trees, but I do know about hazard trees. Breakaway lanyards or slip off the end of the lanyard friction hitches with TIPs in other trees.
Could you have shot a throwline in the top to bust it out/ test the tree before climbing? I did a dead top removal out of a western red cedar yesterday. I had the top swinging 3-4 feet off of center with a throw line before entering with a remote TIP. Shook out some small, dead branches that might have fallen on me from climbing. I knew that i didn't really have to fear the top breaking out mid-ascent, and that the tree was somewhat stable at the roots. I had my pull (throw) line already in place.
Was there no risk of root failure? Stem failure?
There is the famous mountaineering expression that Paul Petzoldt used to use, "There are old climbers. There are bold climbers. But not old, bold climbers." Bold John Bachar died free soloing (ropeless climbing) recently. Bold Dan Osman died several years back with rope jumping due to bad judgment. You hear all about the tree accidents.
We just want everyone to be safe, and learn from each others triumphs, mistakes, etc, and very, very lastly, accidents.
Seemed like you were bragging about what a gnarly, dangerous tree you (short-cut)climbed. Not a good example to set for less experienced people.
One more Petzoldt-used saying. "Good experiences comes from good judgment. Good judgment comes from bad experienes." Collective bad experiences in both mountaineering and tree climbing are usually grievous.
Be safe. Charge people what it takes to do the job safely, or walk away. Order a new rope and come back. Just don't let hubris get in the way.
Around here, often Good customers have a lot more respect for a professional having the technical skills, judgment, and equipment to do a hazard removal safely, than Cowboying Up, IMO.
