Hi Logan
So you have the outer 10 mm not contacting when you use the pencil test? That's to be expected when using the chordal stroke.
It probably won't take long to come into contact at 80 grit but I can't give an estimate. It depends on your technique which I can't see.
I know you are probably sick of rough grinding but you are getting close. I find the early stages of grinding a bit tedious but it gets a little more interesting and quieter as the grits become finer.
Keep up the good work.
