Couldn't find the big stepladder to jury rig the big ladder to in order to attack the higher branches. So I resorted to the 5m long manual cutter thing. This may be a good move.
Managed to start pruning the smaller peripheral branches and one of the 3cm thick ones that was actually interfering with the overhead cables. It's really tough work to engage enough power. On the second one I think I just tore my right bicep as I finally got the damn thing to cut. Bugger.
Waiting to see how bad the damage is. Still, it beats any sort of chainsaw mishap.
Ok, right bicep tear is painful but there's no lump of muscle tissue that I can see so it's not completely gone. I'm now mainly using my left arm and angling the cutting head to be optimal for each given branch.
Or I was. I now have an impromptu artwork in the garden as I may have slightly over-lengthened the cutting tool. It's impossible to bring down as the two parts are detached and the top half is cutting into a branch. Oops.
@davep Uh oh.
I don't mean to interfere with your work processes, but might I humbly suggest that this is an excellent point in time to put away those tools, see a doc about that bicep, and call in a professional to take care of the tree?
