Title: Here's a Great Historical Reference About Sharpening
Post by: RichColvin on April 26, 2018, 09:54:18 PM
For those who want to read the wisdom from our elders, this book :

Turning and Mechanical Manipulation, Vol. III
Abrasive and Other Processes not Accomplished with Cutting Tools

by

Charles Holtzapffel

was published in 1850, and then updated by Charles' son, John Jacob Holtzapffel, in 1894.

Recently, it was digitized by Microsoft, and is available at :  http://huk1.wkfinetools.com/02-Toolmakers/Holtzapffel/pubs/1850-turning-mManipul/1850-TurningAndMechanicalManipulation-Vol.3.pdf

There is some really good information about abrasives used in sharpening and honing that many might find interesting.  If nothing else, there are some really cool pictures like these :

Just some fun for your day !

I'm just happy my Tormek doesn't have a treadle to drive the wheel !

Kind regards,
Rich
