Feel free to ask questions about the referenced thread. We know that some things are not as clear as we think they are. No question too basic. No question is dumb. This message is especially for DIY'ers new to grinding. Maybe a better explanation or PIC s could help.
I looked today in Home Depot at blades for various makes. Seems like many are thinner than the ones used in the thread. Also hole geomety varies. Saw some "wavy" blades also. None of this should stop you in your sharpening efforts. :smile:
