This China made grinder works pretty well. I did buy some Italian made grind wheels from Bailey's. Heard some folks had the Chinese wheels fly apart. So thought I wouldn't chance them. The 3/16" wheel is the one you use for standard 3/8 chain. The 1/8" wheel is what you need for the smaller 3/8 LP chain. This grinder will do the "tilt" if you want to. I have done it both ways, can't tell hoot of difference. LOL
Gregg,
Bailey's is apparently out of stock on that one. After much effort, since it is not listed under current grinders, I managed to get it to come up. Baileys has a review comparing it to the non-Chinese 511ax. They pretty much nixed it giving a long list of issues compared to the Italian one. I did find some of them listed at other places with various paint schemes and brand names. Cheapest was about $170. Even found a Y-tube showing trick to reverse motor for controlling feathering of the grind. Seemed like they were spinning the wheel for the same direction as filing a tooth.
A thought occurred to me about excess heat of grinding, if that occurs. From my days of grinding long ago, if I remember correctly, the most heat is at the last (as the wheel spins) part of the object in contact with wheel. And since that is often the thinnest point if making a blade, it being thinner makes it harder to move heat away from and thus the bluing.
Would it be better if the wheel was spinning so it's first contact with tooth is at the point of the chisel?
