Oh yes! Thanks for showing that. I'm certainly leaning toward trying some full chisel but I'll leave the square filing for some years I think. Bucking those rounds in the vid thumbnail only took a few minutes (but years of learning to sharpen and hone mechanical skills. - How much more energy is there in a kickback with full chisel compared to semi, is it like double, triple? What's your sense of it, if you can remember. (I live alone with my disabled son, am going into firewood so he can do something simple and enjoyable while making some $$. Is more power needed to pull full chisel? I use a FS 291 (55cc) with a 20" bar. When fully in a dry hardwood log it goes through at a slow and steady pace, it can be pushed only a little when maxed like this, or it bogs. Cheers sincerely d
Kickback doesn't really change between them. If you are looking for a great explanation on how it occurs and general safety, search for Dan Tilton chainsaw safety on CZcams. It's from the early 80's and goes for an hour but there is a lot of incredibly good information in the video. Even watching what I did here, you can see my left thumb resting on the handle instead of being wrapped around. Thats a bad habit I picked up somewhere over the years and I need to think about it when using a saw to stop myself doing it. Power wise, it's a bit of a wash. Full chisel is doing more work in a pass clearing the fibres in go, semi has a few bites at the wood to achieve the same thing. FC needs more power but is also more efficient, so it balances out. For the work you're doing I would stay with the semi. All of this is a bit of a hobby for me now, when I was making money running a saw, all I ran was semi chisel because I spent more time cutting wood and less time sharpening chains. The cutting speed shown here has more to do with throwing horsepower at the problem than the chain.
Hi@@SawChainTheories Thank you very much for the reply, appreciated! Yes I looked up that beast, almost 90cc. I've still got the better part of 4 loops semi chisel to use up before I need to worry about new chain. I decided on Carlton semi chisel years ago after reading the experienced experimental advice of someone called Laurie in Qld. Since getting a Stihl FG2, sharpening has generally become a pleasure, though it still takes some time to do 4 loops @ 40 teeth each. Found the Dan Tilton video, have saved it. Breakfast is done, back to doing things, will watch Dan on breaks through the day. Cheers sincerely d
