Cheers again folks

 

It's in Cove, Argyll, not too far from Helensburgh as the crow flies.

 

Yeah Sitka strength/fibres etc never ceases too amaze me, this piece was about 8ft long and heavy yet the hinge did not break when I push it over into the rigging.

 

Notice the sapwood/bark tear towards me because I started the release cut on the wrong side - hits my foot, never felt anything but it's these little things that'll catch you out in treework. Had I started the cut from my side it'd have rolled off the other side. I thought I was cutting it straight along the hinge. There's a lot of footage from this job which I'll put together sometime and post but thought this little incident was worth posting by itself

Too close for comfort eh Tim?

 

Lotsa guys nip the sides of tenacious conifers.

 

I know I learned about it the hard way!

 

Love the honesty of not editing the little mistakes.

 

Looking forward to the series you put together.

 

You almost have me sold on those friction rings, but not quite yet.

 

Soon perhaps though, for minor course changes.

Would never put them in for heavy vertical sections like that and cant remember a time when it's has happened before (maybe happened so long ago I've forgot)

 

In the vid below the first clip was from a tree the day before and it's how I'd always approach a conifer top when dropping the head out especially on Sitka and Norway Spruce.

 

I've slowed it right down so you can see the undercut having the proper effect by stopping the tear out. The final clips are the next section from the previous vid

I think the first few times it happens it's an end of the world feeling but when you have been doing the job for a while all those sap cuts, gobs, undercuts etc are all time consuming.

Why no fell straight fell onto that big lawn and just fix the divots?

Love the slo mo Tim.

 

Your ropeman's good too!

Nice work Tim,Looked a tall tree.

 

I always leave couple of branches at the top when rigging those heavy spruce/fir tops.Mass dampening and all,IMO.
