Are the terms interchangeable? And if not, when would you ask for a base grind vs a stone grind?
From what I understand, and this may all be wrong, but a base grind is only when you need to flatten your bases or have major base damage? And a stone grind is only to add structure and doesn't take much material off?
If you want to change your base edge bevel and make it smaller, you would need a base grind right? A stone grind wouldn't be used to reset edges?
And now if your base and edge bevel was set at the beginning of the season and you're happy with it, you've been manually maintaining your side edges and deburring religiously at home, and it's now the start of next season and you want to get the skis a machine tune to start the season. What would you ask to be done? Just a stone grind and edge sharpening?
