I never said it was wrong, nothing wrong with using the back of the bar at all, as long as you are carefull to avoid kickback. As far as "steering" trees by cutting off part of the holding wood, I figure you do this using an intentional Dutchman. A big no-no here also. That being said, I firmly believe experienced fallers should be able to control their own destiny and fall how they want, within reason. (but not dominoing 30 trees at once type of stuff) Ross, the thinning you talk about I think is like spacing here, cutting down culls and competing species to "build" a good new forest. I did that like 10 years ago, real balls to the wall, tough work. Sometimes it can be real thick and you have to use illegal techniques to make it lie flat. You know, running a saw way above your head to block stuff down, one handing, whatever. In this book Timber and I have talked about it also says you have to make two escape paths away from the tree, well brushed out. All kinds of good stuff, I gave my copy to a new guy, but I had read it many times. About the wcb, that publishes safety stuff, I have been to the head office and got stuff, like books on yarding systems, splicing cable, helicopter stuff, etc. but with the new govt. they have got all stingy and cheap, about everything, especially helping injured workers.
