Maybe interesting?

I’m a 70 years old Dutch craftsman and sharpening and hone stone collector. My age told me its time to write down my knowledge.

So I wrote in 2011 the first part of Grinding and Honing. See Index website Henk en Ge Bos and Download pagina INFO 20M

Contents of part 1with 167 pictures:
Chapter 1. The stone of Bert Meijer; Cause and effect of the search; Travelling to Petit Sart in the town of Lierneux; Musée du Coticule; Occurrence of Coticule.
Chapter 2. Difference between sanding, grinding and lapping (polishing).
Chapter 3. Historical abrasives.

In 2012 I wrote part 2 with 275 pictures:
Chapter 4. Types of Natural whetstones. Definition stones; classifying stones, Igneous stones, Depth stones; flow out stones, Fission Rocks, difference in hardness, Sedimentary stones, Origin of sedimentary stones, Solid deposition, Granules, Less durable, Metamorphic stones, Origin of metamorphic stones, Structure and texture, Size of particles, Sandstone, Quartz sandstone, glauconitic sandstone, Psamnite sandstone, Arkos sandstone, Grain Shape, Slate, From mud to shale in 7 steps, Slate and size of grain, Slate and honing stone, Coticule, Novaculiet - (Arkansas, Charnley Forest stone, Turkey, Llyn Idwall).
Chapter 5 Acquisition of stones and then…
Difference grinding, polishing and honing stones, Designations of stone, Historical finds, Cleaning dirty stones, Method to determine what kind of stone, Lapping a stone, Lapping machine, DIY honing stone, Gluing, Water or oil, Cleaning; storage; boxes, Database, P Grit ruler.

Mooi werk Henk.

Fantastic, thank you! I even saw a picture from Sweden and the lime stone island of Gotland - I used to live and work there for three years (and my daughter's born there).

I've already read it in Dutch, it's a must read

Thank you for passing on your knowledge, thank you so very much!

Henk,

Can't wait to read this more thoroughly. Im very grateful to you for taking the time to compile your knowledge and passion for sharpening stones and then share it with us! Look forward to the next installment.

Best Regards,

Howard

Very very informative in my quick perusal of chapter 2. I appreciate the .pdf format and assume we have your permission to store and spread the file about un-altered. If you object, please say so. For any users who may have qualms about opening a random pdf file on a site that appears to be about random nautical things, I run GNU/Linux and the both opened properly and displayed appropriate content to the end of file, however I am not able to actually scan the document for viruses or malware (they normally wont open properly though). The beginning of the file also mentions its main purpose is about the stones maritime people use to maintain their tools, the common shaving stones are of course a subset. It also goes well beyond that.

I read the english version before it was made available too, Piet, and corresponded with Henk - I agree that it is very good indeed.

James.
