Hi Bernard, my chains are probably at par with Dennis Cahoons and Tommy Fales, ok, however, I don't put the 40 hrs./chain that they do. I simply make sure that all the cutters are exact in length and that the gullets are cleaned out and the corner is exactly in the corner. Then I take the rakers down all the same height before I tickle it one last time in the grinder to take off the slight indentation that the raker gauge leaves in the cutters.
I don't do any thinning or stoning. Jarod paid 190 US/chain only because he insulted me and called me a sawed off runt with an exibitionist complex, but I would only charge you 75$ US. delivered. I gaurantee that you can win any race you attend, and why wouldn't you?
As far as hand filing I would stick with the grinder, in fact, get a Silvey from Jarod, you can't beat his prices.
