Sharpened six 3/8×84dl stihl RS chains today and one 3/8×72dl Oregon with the anti-vibe ramps on it. Went well, but they were damaged quite a way back.
This one had been touched up by someone, but whatever they used only hit the cutter about an 1/8" down. Funny when guys say a shop ground half their cutters off when they sharpened their chains; well if you beat the heck out of them so much that the working corner is damaged back half way, I guess they probably would need to remove a lot of material to actually get them sharp. Also, none of the rakers had been touched on any of these chains.
These take me a lot of time as I start at the front and clean the gullet out. But, when they are done, they cut straight, self feed, and are easy to sharpen with a file or with a grinder the next time it's needed.
Sorry the pictures aren't better, my lens is cracked on my phone.
