Lots of tree felling videos! (CS32 chainsaw course)

Well, I've been busy editing videos from the CS32 chainsaw course I was on this week, so put them full-screen, turn up the sound and sit back...

First, felling an oak tree that then gets hung up, and how it is taken down by severing some of the hinge:


Here's the slow-motion reply of the bit where several trees knock each other over - this is why everyone's meant to be two tree lengths away...

CS32 Medium Tree Felling chainsaw course - felling oaks

I've had some time off work this week to do the CS32 Felling Medium Trees (380-760mm) chainsaw course. Our instructor is David Rossney of Esus Forestry Training - Tracy and I did the coppice harvesting efficiency course with him a few years ago too. Basically, after this course, and exam, I'll be qualified to fell trees up to 30" diameter.

There's some felling videos to come in a moment, but first a few pictures. We've been learning about properly removing the buttresses of the trees:

How to make an accurate gob cut when the tree is wider than the chainsaw bar:

and also about high-lift felling wedges:

and how to use them:

OK, here's a quick video showing just the highlights (i.e. trees falling) from day 1:


If you'd like to see the whole process, and what happens on the CS32 course, here's me felling a tree:
