I'm going to see if I can give filing chains a shot. Some guys really like it, some not so much. We'll see where I fall into that. So, a Pferd and log vise, ordered, and arrived. At first glance I may see why I thought hand filing was difficult and a waste of time. The simple oregon single file holder and depth gauge file I did have now looks lame and inadequate for the job compared to the Pferd. The Pferd is heavy, seems solid, and has multiple files for right and left filing, and with an integrated third depth gauge file. So you can file right cutter and depth gauge, flip it, then left cutter and depth gauge, without having multiple tools or setups. It feels strong and hefty to the hands. I think I'm going to like it. There is a new chain on the saw that has been through three tanks on red oak. I'll give it a try and see if I can get it down. And then see if it fits in with what I do.
