i dont think you can consider yourself a proficient sawyer if you cant file by hand.
in fact i'll go a step further and say if you cant sharpen a saw freehand you shouldnt be running one.
I'm gonna cop some flak for these comments but here goes
...
I've seen a number of chains from guys who "think" they are good at filing a chain and the truth is they're not.
Because its blunt, they file it, it cuts better than it did before, so they think they've got this filing thing "fully sorted". Bad filing also really becomes evident on longer bars too with crooked cuts. Even the worst filer can be convinced they're doing a good job on a 16" bar in 12" wood. On a 42" bar in 4 foot wood they wouldn't stand a chance. I believe there is a big difference between "touching" up a chain and actually "filing" one. Anybody can touch up a chain that is only slightly dull - filing a damaged chain back is a different ballgame.
I won't lie, I grind all my chains now. If one goes blunt, I swap it out with a freshly ground one. I can swap one quicker than I can file one. I can always grind a chain when I get home but I can't cut in the dark. I'm certainly not the best filer in the world but do know what needs to be done. Bare in mind though I rarely cut green, clean wood where I only have to sharpen a chain a couple of times a day.
In really bad conditions I might have to swap out 4-5 chains an hour (semi chisel too!). If I had to hand file this amount of chains I'd be filing more than I'd be cutting.
I also recently got hold of a heap of ex rental chains and if you think you could have hand filed this lot you must have a lot more spare time than me. You would have used a lot of files and had some awesome blisters
Grinders seem to cop a bit of flak on this site which I believe is from one or many of the below;
1) Idiot operators.
2) Guys that have never used or owned one.
3) Because daddy never ground a chain.
4) Because daddy said they take off too much metal.
5) Because daddy said you'll blue the cutters and take the tempering out of the steel.
6) Because people can't afford one.
7) Because they only own a couple of chains and don't have enough to make it through a day in the field.
or 8) (the disclaimer
)Because you are one of the few that actually know what you're doing.
I have a real soft spot for the guys that say they hand file for a while but get the chain in to be ground to reset angles etc. At least they're looking outside the box. I'm not anti filing for one minute, so it surprises me that some people are so anti grinder.
I actually have to complete a large tree felling competency course soon so I can do work on a corporate farm (part of their safety regulations). Some of the course involves hand filing and saw maintenance. When I told the instructor over the phone that I don't file very often and grind most of my chains he asked "how many bloody chains have you got?". He didn't realise I have a business selling this stuff and have about 10-20 chains on the go for each of my 18", 20", and 32" bars. If I couldn't get chain so cheaply and have a sawchain/bar etc business you never know, I might be an avid filer as well
I also always have spare files and guides in my toolbox "just in case". Pferd, Husky and Vallorbe are the best files I've used. Stihl good too which I believe are made by Vallorbe also? I have actually filed quite a bit in the past but mainly on Stihl 009's with 12" bars in 3/8"LP when I did citrus/almond pruning. Not a real test of filing skill...
Don't think I'm having a go at those guys who do know what they're doing when it comes to filing, but I bet many of the guys here that rave about filing over grinding have angles and cutter lengths all over the shop...
Apologies if it took you 2 hours to read my post as well
