Perhaps complexity isn't the right word. Clutter might be more appropriate. I've got files for sharpening on the saws, grinder for off it. Anything else is clutter unless it replaces one or both of those options adequately.
I've been down the road you're on, Kiwibro, had the grinder, a nice one by Stihl. I got fewer sharpenings during the life of a chain, the chain was never as sharp as I could get it by hand, the abrasive grinding wheel sent tiny dust particles in the air and on the bench and on the wall in back of the grinder, those machine-sharpened chains then won't take a hand file without ruining the file, yada yada, same reports as you'll see all over the internet. I got rid of the machine because to me it represented clutter, potential pulmonary problems, repetitive replacement costs of the worn out wheels, regular fine-tuning of the machine to keep consistency, and readjustment of the machine for the next chain if it was worn differently from the former chain. As time went on I was finding I was spending an amount of extra time to maintain the machine to maintain the chains. I
assumed the machine would save me time, effort and money, which is why I bought it. I finally had to admit to myself that I was wrong in this assumption. It didn't meet my expectations in the real-life setting. Your results may vary.
You present an assumption of (clutter, complexity) based on, well, I don't know or claim to know your reasonings, but that's OK. Your system works for you. We all have to go down our own paths. Your system worked for me for awhile until after a great deal of actual, personal, first-hand experience I went back to hand-sharpening.
I'm amongst the crowd that
knows you can get a chain sharper with a one dollar file by hand than with a machine. And like that crowd I hand filed, on the bar, on the saw. And I still do.
Nothing has changed, except now there is an
option, not a replacement, to the way I have been doing it. Let's be very clear on that. The ChainMeister takes nothing away, doesn't require any real change as the hand-filer is still filing by hand. It just adds certain
options that you employ only when the advantage serves you. So bottom line, you call it clutter, I call it options. An option is only viable if the option is somehow better than the norm.
With this device, from my own personal experience, it becomes more useful, and you find more uses for it the longer you have it. That's the general report treestuff is getting from others. And at this point I sincerely apologize that I have
not yet shared the options, advantages and efficiencies you can expect. All I have given is the 'cover of the book'.
I'd like to offer a picture and video based presentation on all that I know of this device. As of this time, a have only replied to responses. I've given nothing of value, and for that I am sorry.
