Boy just said that it -28 here at the house, the probe is not that far off the house. So may not be accurate.
If you mean cutting into the side strap . (opposite side of the chain as the cutters ) it can and does happen with both chisel grinding and chisel filing.
Nope , still not making the connection . It comes from the bottom of the leading edge of the stone ( wheel) . Regardless of which chisel grinder is being used. I do it a fair amount. Because I dress my verticle ( cutters verticle side) quite fat. Meaning I get a much smaller gullet when I grind. Helps cut some of the stringer fuzz that impedes free bar travel in the kerf . On bigger coastal red cedar and cottonwood. And it doesn't impede any thing on spruce and hemlock. Hogs out red alder like unbelievable also. I also run a lot of side hook with just a bit of beak. At least I do if I'm running close to a 6 cube power head. With a smaller ph. Say a 372 or 460 Stihl. I straighten it up more and run my riders a little higher. Say 30k instead of 40 k+. I run my top underside shallow and the top at around 25° . My grind or chisel file job blasts our Alaskan conifers tho it's not for the uninitiated on the Humbolt in a western hemlock. Feeds well in red cedar and even blasts thru frozen ( -50°F ) white birch . Gotta be strong to run it for 6 1/2 hours trigger time in a 6 3/4 hour day. Sometimes there are just too many questions. But most don't have and won't have the benefit of years experience on top cutting crews. For chain and bar longevity, my grind is a little too radical. Its also hard on crank bearings and mounts and drive sprockets . But , it's flat Inspiring with a hopped up 6 cube power head With a 32"-long 36" bar. I.e. Windsor Husky mount 36. = 119 drivers in 3/8s and 106 in 404.
The only way anyone could tell anything about a chain being ground on an SDM4 or a Pro Sharp would be a mark from the tooth hold down pal or lever . And they don't leave a mark on the chain. Otherwise, anyone thinking that or agreeing with it has probably been into the Rum , or maybe them wavy cigarettes. How a grinder is set up and dressed. Is all that can be seen by looking at a grinding job. Not which brand or model of grinder. Even with a real zoom lenses . As a tooth is ground away or the stone wears to a smaller and smaller diameter , certain assumptions can be made . But even with a Silvey Pro Sharp. A guy can do a funky job of grinding . Which will throw how that grind looks out the window. . I think someone is just talkin chit.
. well, by the time I wake up I'll have probably infuriated half the members on this thread. Sorry, but I stand by what I've said. P.S. I would very much like to see some close up pics of Fabz grinder and especially the dresser set up. Balmy 16 underneath atm here at the cabin. Night all. Have a fun night at work Tom.
