good thread Frank, great pics guys. Rob thats how you learn mate, as big ammer says, its now experience under your belt.

 

Nice Stevie. Did your apprentice do that for you? Haha.

 

Just jesting, nice and low to the ground, level back cut at a nice height, sharp saws. 8/10

[Big 'Ammer]

Here's another hinge, or lack of.

 

About 20" diameter.

 

Not sure how much sound wood on the right hand side and didn't want the tree to swing that way if there was more than anticipated.

 

So, over-cut the top face of the gob to deliberately ensure the hinge failed and the tree would pop off forward in the right direction.

Can I just say that stihl hi-lift wedges are banned from this thread as they suck ass.

 

Nige, that looks horrible but I get what the thinking so......5/10 for thought not presentation haha.

[MattyF]

whats the beef with hi lifts ??? think they come in very handy for stunt fells would not leave home with out them ....or a bottle jack!

Here's a bit of steel wedge action for you, Frank!

 

Also, this one illustrates Steve Bullman's earlier comment about using the buttresses for hold on rotten trees.

 

Knackered beech needed felling away from trees being retained and a large tank to the rear.

 

Crown was weighted over the good side, so couldn't just wade in and cut it down as it would have failed sideways.

 

Cut a slot through the centre to see what the extent of sound and rotten wood was.

 

Cut the back out, leaving a small piece of holding timber uncut near the left hand buttress/rib and kept lifting the far corner up with some serious hammering in of wedges in pairs (hit one and then the other, it works really well).

 

When it was picked up far enough, cut through the little holding piece and used the front buttress to keep hold of it.

Being a little naughty as you know Dave, and perhaps not right derailing the thread, but i do feel i have a point.

 

In answer to you, i am sure it is possible for a wedge to come adrift, splinter, or even fly out due to defects/damage to the wedge, possibly having catastrophic results.

 

Oh, and i do know its already covered by PUWER Bob!

 

I have broken one of those wedges. Right where the wood meets the Ali. Now I have 3 good ones and a broken one! I've put two rings on the end. Stops the wood mashing up as much. Bit of insulation tape to hold it in place and they work well

[Mesterh]

couldn't work it out at first.. its the print off the bottle jack, thats a long hinge:thumbup1:

 

Nice bit of spotting:001_smile:

 

Hi-lift Alloy wedges FTW!!!!!

 

Although I have smashed a few to bits in the heat of something not moving.

[18 stoner]

If its maintained under PUWER, those things won't happen

 

So therefore any other "lifting" device wouldnt fail either if maintained under PUWER?

 

No need for LOLER at all then?

 

 

 

 

The point is, does it lift a load, YES or NO?

 

If the answer is "YES", it should be LOLER'd.

slowly working out how to get pics off a memory stick.. here goes, ash cut high as there were rocks jammed in lower down and a footpath circles the stump,(they get slippery you know) shallow gob into decent wood to create hinge in best timber at sides, followed by bore and release..
