I am not trying to downgrade the FG2. It is an awesome tool, BUT it does have it's flaws. For what a new one cost I think it should have had some things refined a little more than they are. For instance, the tooth stop only holds the tooth really well when sharpening one side. When you go to sharpen the other side the stop doesn't hit the back of the tooth the same place and the chain can slide off the stop if your not careful. The vise is not as good as I think it should be. For the price of the tool, it should be perfect IMO. As far as construction as a whole it is very well made, but there could be improvements.
If I would have paid full price, I would have been a little disappointed............until I saw the cutters. The chains cut so smooth it's crazy.
The way I have things set up now I have 9 twenty inch chains, and 3 twenty four inch chains. All these chains were given to me, so it's easy to take several and just swap em out as they dull and then resharpen them in the spare time.
The point I am trying to get across here is, if I were in the tree industry making a living I would rather have a timberline for ease of use in the field, so I could sharpen on the go as to have to sharpen chains at home when I could be spending time doing something with my family. I mechanic for a living, so the last thing I want to do at home is mechanic on my own cars. That's why there is something wrong with all of em.
A lot of people on hear, me included do not use a saw for a living, so taking the time to use an FG2 is irrelevant. It's part of our hobby, so a nice well sharpened chain is worth what it takes to get it.
I may shoot a vid of the setup and use of the FG2 cause after a quick search I could not find one on youtube.
