Thread: Cutting Shapton Ceramic on Glass...Results

Alex aka Philadelph had spawned an interesting question and debate as to whether a Shapton Ceramic on Glass stone can be rip cut in half. I liked his idea of trying that on a 1k stone to end up with a narrow bevel setter. Some speculated that the glass substrate was tempered and therefore would NOT cut without damage and instead would break into tiny pieces. Others thought it would cut just fine; while still others (myself included) had no idea.

Here we go:

The tool:


Success?...........


Ouch, the tempered glass speculators have it by a mile!



Yeah, I heard a "tink!" pretty much right after starting the cut, I kept going because the ceramic was cutting just beautifully on the water cooled diamond saw.

But, the adhesive is holding the glass very well and I beveled the cut ceramic edge on both halves and I'll say I still consider it a success because I have a narrow bevel setting hone and I'm going to run with it. Worst case, if the glass pieces start falling off, I could bond the thing to a flat water friendly substrate with some JB Weld or something and I'll be just fine. Randy Tuttle has dibs on the extra one.

So.....mystery solved.

I would take my hat off to you if I had one Chris. Chances are the adhesive is good enough but you might go ahead and glue it to another surface as is for insurance.

Even though you used the cheapest Shapton glass hone- you got balls and I'll give you max props on that trick. There was only one way to find out if the glass was indeed tempered

Well, you proved Shapton isn't involved in false advertising- the glass is TEMPERED! But one thing is for sure-the ceramic abrasive media is FIRMLY bonded to said glass. My guess is that if you epoxied that hone to another piece of glass before using it-you'd be good to go!

I figured you'd take the jump sooner or later. Good job. HARD CORE HONE ADDICT

Well, Jimmy, I'd never have attempted that with any of the other Shapton Ceramic on Glass stones since the 1K is the least expensive at approx $40. If it had cost any more than that the risk would have been too rich for my blood. I have plenty of narrow natural finishing stones, so having a narrow bevel setter is going to be nice.

Don't I know it, Lt.!! Ugh, when am I going to find a cure????

NIIIIIIIIIIIICE!!!!!!!!

Wow, I really admire that. I am just really happy that you did that and have little reason to be since I already got my Pro stone lol. Anyway, congratulations man. I agree with one (or more) of the above posts that if all else fails just epoxy that sucker to something else either under the broken tempered glass or directly on the ceramic if the glass comes off. Really nice job.

The crack pattern on the glass sure is pretty! I would suggest coating it with clear epoxy to keep it all together over time or bonding it to another piece of tempered glass to preserve the pattern and to keep the Shapton grit markings visible. Thanks for having the guts to experiment and for solving this problem of narrower Shaptons.

Go to Lowes and buy one of their 5 dollar granite tiles, 1 sq foot. Have them cut it on thier diamond watercooled tile saw for free to the same size as your ripped shapton, and glue that sucker. The granite is thick and sturdy, and it is as flat as anything else you are going to find, so it would influence the flatness of the shapton the least... Granite is inert, and being thick it would be harder to break than a scored and cut piece of untemepered glass.....

My, you kids and your crazy wild schemes! nice but i won't be doing this with any of mine, but it is good to know that it can be done.

You could epoxy bond / glue it to a piece of glass or granite, and prevent the shards from ever falling loose.
But kudos on this neat experiment. One of the great questions of our time has been answered
