I picked one up for $25 bucks a few weeks ago. I've got 5 chains & after a few years use on scrounged wood some had damage & others just seemed to not hold a sharpening so I figured the angles were off from hand sharpenings. The HF unit was way cheaper than taking my chains to a pro to get ground to a stub for $8-10 a pop.
I spent about a half hour tinkering with initial set-up, putting a few washers on the main hinge and the chain brake, looking for problems... First chain wasn't the best, but I quickly learned it's quirks & now I'm getting good results. I tried doing the rakers with it based on a method I saw on Youtube, but it seemed sloppy & slow, so I just did them by hand. It's taking me about 10 minutes per chain.
I thought I'd just use it every so many sharpenings or if I hit something, but now I think I'll just stick with grinding them all & switching chains in the field. As MasterMech pointed out, switching between grinder & file actually makes hand filing slower and takes more metal off because the file & stone have different profiles. Picture switching a knife blade back & forth between straight ground and hollow ground. Not a big deal if you just want to stick with one chain, just be aware it may not last as long.
What kid of tinkering did you do with the washers? I am going to hopefully set mine up over the weekend and would like some heads up.
