I watched that video and was not impressed, it was certainly a simplified version. he showed nothing about dressing the wheel and his was dirty after he did the first side of the chain.
I did like running the cord down the pipe tho.
Because I cannot stand for the time it takes to do a chain I sit on a stool to grind chain, so I didn't lock the grinder to the pipe with the setscrew, when changing sides on the chain I just spin the grinder on the top of the pipe so I do not have to move physicaly , I did grease the top of the pipe.
You have to watch that corner carefully, as you grind and dress the wheel that corner keeps changing, you have to stay on top it.
It seems every chain is different, I've done lo-pro, .325, & 3.8, . I've only had this grinder for 4 days, I'm sure there is so much more to learn in the days to come.
