OK impulsively in the last few minutes I looked at an eblag auction and saw this <click pic for more>
http://i.ebayimg.com/00/$%28KGrHqUOK...%7E%7E0_12.JPG
I picked it up for £26 and am hoping that its a coti that has come adrift from the schist, what do you think? If I'm right any advice on backing it would be great.
Anyhow at that price, coticule or not, if its any kind of finisher then I'll be happy.
Any slate or what have you will work as a backing. It does look coticule like and if it is I would look for a blue to back it up. IIRC there was one in the SRP classifieds last time I looked. Not sure of the size. Good luck with it, hope it is a good one.
That's from ebay seller Taylors1000 and they are great, that sure is a coti. Congrats!
Some folks set them into Plaster of Paris and trimmed the stuff away from the edges of the stone to give a solid base to a rough backed stone.
It seems that there were a number of different backings used on a Coticule. BBW, slate, cement. Those are the ones that I know of, there were probably many others.
Well I was considering cutting down my dragons tongue but I've been offered a slate tile. I'll need to buy an adhesive so I'll see what's available locally at what price!
If I were you I'd go old school and counter sink it into a piece of hardwood. I have seen coticules housed this way before, and many other finishers, particularly Charnleys and Jnats. You could even make a lid for it with dowel either side to hold them together securely.
Although I'd assume it was a coticule in the absence of other possibilities, it comes from Taylors. Great seller by the way, I have done business with the man several times. He sells coticules at times, so I'd also assume he'd know what one is. Either way please post pics and observations when you receive it.
Epoxy works really well and is cheap. Use the slow curing one. It will never come apart afterwardsQuote:

If he said it's a finisher, I'd be willing to bet it is & if my HAD was nipping at me I wouldn't have been concerned with the seller...just the price as I have noticed a lot of his stuff goes a bit higher than other sellers. I look forward to hearing how the new rock performs.
Well its here and I'm 80% sure its a coticule but the only one I have is somewhat different from the norm and this one is a lot different from it.
The interestingly figured side is the flat one while the dished side is pretty uniform, I think rather than attaching it to slate initially I will route out a piece of hardwood and fill the dished hollow with miliput (epoxy putty) which I have already and mount it in the hardwood like an old fashioned barbers stone, as per Scipio's suggestion. I will put cling film between the putty and stone so that it just forms the shape than decide whether to glue it permanently later.
I have a nice piece of walnut which is the right thickness already so if there is no major reasons why I will use that, but equally I have some cherry, oak or beech that I could also use if they would be significantly better.

My kids go back to school at the end of next week so at the moment I've not got a lot of time to myself, family comes 1st, but come September I'll set to testing this chunk of rock in earnest.
Looks like one of those hybrid coticules. They are meant to be very fine. There is a thread with an example.
Yeah, does look like a hybrid. If it was mine I wouldn't mount it to anything. If too much material was going to be removed I would lap the dished side either. I'd try it first, on the dished side, and see how that went. If it was alright even dished I'd use it. If it is a hybrid the other side can be used too. The only one I had was very hard on the hybrid side. I sold it some time back but anyway, nice stone you've got there.
Well a quick try last night on the hybrid looking side was a little disappointing and appeared to be in the 4K or 5K region to me which I suppose is akin to a BBW but I don't own one to know for sure, certainly it wasn't anywhere near the kind of edge I get from my Ardennes Coticule. It has been mentioned to me that the previous owner clearly had a preference for one side so I think I shall see how the dished side works.
As it stands the jury is still out as to whether its a coticule at all but it still is a handy stone whatever it is.
You may as well lap the dished side. You don't have much to lose and potentially a finisher to gain.
its a coti the dished side should give a smoother shave i'm not surprised the other side didnt perform as well it looks like i has some bbw mixed with it
