Thread: My coticule broke! :(

I've used 2-part epoxy to glue them back together quite successfully. Coticules are natural stones and I've had several split like yours. Consider yourself lucky that it didn't break through the yellow layer.

I would not use the yellow layer without a better backing though. It is quite thin and whether you glue it back to the BBW that split off or a piece of hard wood, it definitely needs backing before use.

What do you mean with "backing" Harvitz81? Oh and thanks about the advice on 2-part epoxy, now im sure ill use that since i got some for free yesterday

Reinforce the coticule layer with something. If you decide to glue the two pieces together that should do it. You got quite lucky actually, coticule chips or breaks quite easily, as do other honing mediums.

My slurry stone came apart during use (too much suction, I guess). I used crazy glue and stood my mini-anvil on top of the stone while it dried. Seems to work so far.

Not sure if it's any consolation, but this is what happened to an exceptionally fast yet fine Old Rock of mine in transit on its way back home from a friend:

that is a disheartening for sure.

I could be woefully wrong here but, FWIW I really like this Idea. If this happened to me I would make a box for both of them about half their depth and use one as a combo and the BBW as a hone/oversized slurry stone. Just make sure to be VERY careful when flipping the combo. I would think that the box would provide the support needed for honing but I don't know how fragile they are when that thin. I have one 150x50 combo coti/bbw and one small #7 bout both of which are pretty thick. They seem fairly durable to me (especially compaired to my naniwas) but I haven't drop checked them yet.

I really don't know if this idea would work. Still, just the fact that something this amazing happened as a result of an accident, shouldn't it be taken as a sign? Maybe COTICLEASE (?), Roman god of the Quarry, has special things in store for your "2" stones we couldn't begin to fathom!

I'm assuming that this is a natural combo from the posts. From my iPhone I really cant tell if the pictures are of a combo, slate backing, or thin combo glued to slate. Is that glue residue on the stones or is that how it naturally looks. If it is slate then forget all this and just glue it.

Either way though you are one lucky dude. You really should buy a lottery ticket (one is all you need).

Maybe shoot Ardennes an email with some pix and ask for a suggestion or two on how to glue it back together?

They were very helpful when one of mine fissured..

What are the odds? It looks like a clean "break". Are you sure it wasn't glued were it split, before?

These stones are very easy to be glued. Glue it cautiously and there will be no visible trace of this accident.
