Delta VS Grinder

This grinder may not be exactly the one that was used on the Lathe 101 episode (1706), but it was a Delta, it was variable speed, and it was an 8"er, so how exact do I have to be? This had been only the second time in 17 years that Norm has shown us much of anything about sharpening (the other was the sharpening station, Episode 1211, featuring the Tormek grinder). With an appearance in 2006, there's now a third. And as I conclude my April/May run-through of the episodes, I found another, albeit obscure one, and probably not a Delta, so it'll have a separate page.
