Thread: Honing pressure, clear example

So ,I was playing with my kids outside the other day, and they were using that big sidewalk chalk to draw on the driveway.

I was playing along as well.

It occurred to me that the driveway was like a 5 grit hone, and so I did a little honing pressure experiment.


"Honing" the chalk with heavy pressure gave me fast material removal, and also a very rough surface:


The very same location on the pavement, but with very light pressure gave a much more refined finish:


So, for a given hone grit, you can vary your result based on the amount of pressure you use. When setting a bevel, etc. don't be afraid to use some pressure, as you are looking for bulk material removal at that point. But after the bevel is set, then work on going for lighter strokes on each particular hone to finish it off before moving on to the next one.

That's a totally awesome, and simple comparison.

Did you lap the driveway first?

Brilliant.

no matter what we are never far away from this thing of ours

excellent little discovery


cheers Garry

I see clear evidence of overhoned chalk, did you try the HHT

There's a good deal to be said for playing with your kids. LOL.

that was good one.
This is great example too.

Thats an excellent analogy...! Thanks for taking the time to take the pictures.

I'd not really thought of it like that before and its given me a good perspective to mull over on the tube home tonight...!

That is such a clear way of emphasising the importance of avoiding pressure at the latter stages of honing. Brilliant!

You know I always love hearing/seeing other ways of explaining and demonstrating concepts. I really like that little visual using the chalk; simple and easy to understand.
