I know that I could use the search function, and that this question has been asked and discussed probably 5K times on this forum, but I want to ask it again here on this thread, because I value the guys opinions that post on this page more so than all of the other threads.
I've now acquired a lot more different sized bars and chains now than I've ever had before, and hand sharpening all of them is getting to be a PITA, due to having to mount them on a bar, and then on a powerhead etc....So, I think I'm going to get a grinder. Cost isn't a huge concern, I have no problem paying a few hundred bucks for one that you guys think is worth it, but would you steer me in the direction of ones that you guys prefer please? I haven't researched them yet, but I'm guessing that they will all allow you to put them at a 30 degree (or whichever specific angle you want) pitch, correct? In any event, which ones do you guys like and recommend the most? Thanks.
Problem is that your question can’t be answered by this group in this thread. A lot of it is personal preference, techniques, situation, etc. That is why there are so many threads, which are worth visiting.
My general advice is: ‘There are lots of ways to sharpen: everyone needs to find something that works for them.’
The method you choose could be independent of the number and variety of chains you sharpen. As noted above, some file guides (e.g. Granberg style) will work on a bar clamped in a vice, if you don’t have the powerhead.
I am a ‘grinder guy’. I literally have dozens of different file guides, grinders, rotary sharpeners, etc., which I like to try and use. I might like to use some of the others, if touching up a chain in the field. Or just for ‘fun’.
But when I have a *large batch of chains to sharpen, I prefer the grinder for consistency and speed.
*Note that when I get a large batch of chains, they are usually damaged, or filed by inexperienced folks, and need a lot of correction.
If you are cleaning up all your chains at once, a grinder is a good choice. But once you get them straight, you might be able to keep up with filing, if you prefer, or ‘finish off’ with a file, which some guys like to do.
