I've got some questions about HSS tool bit sharpening and abrasive stones.
It's often mentioned that you should hone the edge of a tool bit after grinding them on a bench grinder.
What do you use to do this, and exactly how do you do it?
Which direction do you hone (up, down, both)?
Do you lay the stone flat on the tool bit and hone, or at a slight angle?
How many strokes are usually necessary?
Is there something I need to look for to know when I'm done?
I'm under the impression that if I touch up the edge on a tool bit, I don't need to grind it each time I think it's getting dull.
Is my thinking right on this? Is the normal procedure to grind the tool to shape, hone it, use it, touch it up, use it, touch it up, etc? If so, how often do you touch it up? Do you wait until there's obvious signs of it getting dull (and what are those signs?), or do you try to touch it up after you estimate it's done a certain amount of work?
When do you need to go back to the grinder to regrind it?
How do you touch up the edge? Is it the same as honing the edge?
I'm sure both of these things are quite obvious once you've seen it done.
