All's good and a bit of fun.
Do visit again, and putting tree work onto the big screen would be great, I wish you well in your endeavours.

I have tried to get hold of Graeme McMahon via email to join this threa but he hasn't responded.
Here's a compilation of short videos I found on the net and stuck together, pay attention around half way through.
This guy knows his stuff, I have also seen him levitate blocks off stumps using two highpoints. He cuts through a large section and it sits up then gets carefully slewed off and lowered by controlling tension on two opposing ropes. This guy is the big tree guru in Oz.

There's a video 6.2mb WMV from his website of some stem wobble. Click on the Triplet Head Falls video on the left hand side just above the block of green and counter.
http://sherbrooketrees.tripod.com/sh...vice/id11.html There is a problem though Andrew. The people you said you worked for in the first post have requested deletion of the thread, they are not happy with you and your misrepresentation. Perhaps you need to rewrite your first post and remove any representation to anything other than yourself. 
If you have trouble doing that simply PM or email me with what you want done and I can help.
