I think -- the word coticule was coined to refer to, in general, 'whetstones' of the spessartine-quartzite type..but I could be mistaken.
I recall one of the razor hones at my Dad's is "Vulcanized" implying it is an abrasive set in hard rubber. I have an identical "stone" but it does not have the label.
Very interesting using shellac and an abrasive powder, do you set it on a substrate or use it self-supporting?
Actually I did read about Grinding wheels being help together with vulcanized rubber. But only with wheels designed for being spun at high rpm's. And at first I am going to try it using a mold. From what I have read from the problems others have had with there first hone casting was air bubbles. Because you are using 3-9 times more abrasive than adhesive (depending on the properties you want of your hone). Which can be avoided by either pressing the mold or adding a thinner. I already made a hone with different materials yesterday with different ingredients. I'll post some pics when It is done curing.
3 days cure, not too bad. Did you start with dry shellac, or did you use something that was already mixed? What is the abrasive in this stone?
i say go for it!we used to pick up ar stone off the ground and work them into a flat shape.made some good one if i recll correctly.being in sw ar its easy to find good stone laying around everywhere if you know what to look for.ive never tried to cast a hone stone but it cant be that hard if your willing to work for it.

I used extremely fine grit foundry sand. Just tested it a little bit, and it works! It feels really smooth, polishes and hones like a finishing stone. And the sparkles you see is the quartz/silica in the foundry grade sand.
If you don't mind me asking, what was your mold? The shape is about perfect to me and I'm looking to try something very similar with the Linde-A purchased this past weekend.

It looks nice and a pleasing shape, but I prefer longish narrow hones. Ever think about a piece of plastic pipe? It can be formed rectangular or left round. Just a thought.
Recipe when you think you've got a winner!!!
Why not try JB-Stick?. Its a two part, steel reinforced epoxy. Its clay like in its unmixed form. While your kneading the two parts together, introduce the abrasive into the mix. Knead it to distribute the abrasive throughout the epoxy.
After the abrasive has been added (and kneaded) shape the clay like epoxy into the shape of your hone.
Its waterproof, and because you mixed the abrasive completely into the mixture, you will always have fresh abrasive, even as the hone wears.
Total time for the JB Stick to harden is 20 minutes.
JB Stick is manufactured by the same company that makes JB Cold Weld.
Good luck and if you try it, let us know how you make out.
Thanks for the appreciation and interest guys. This is something I'm serious about. Who knows, maybe someday when I get different recipes for different grits I may just add them to my business.
I was in a lapidary shop recently and saw a very interesting piece of petrified wood. Unusually uniform, I spent a little time running my fingers over it and thinking. Might go back and pick that one up. Make a nice paperweight if nothing else.
Of course, that doesn't mean I've lost any interest in the hone making endeavors. Just another interesting avenue of inquiry.

very nice i never thought that youd get around to it.
put up a pic of a honed edge on this hone when you can
