271597 "dks@t..." <dks@t...> 2020‑08‑10 restoring a delaminated Belgian coticule hone
I have a boxed 4-15/16 long x 1-5/8in (natural) coticule stone which has been
delaminated. I would like to restore it but am uncertain what glue to use after
cleaning with alcohol. I can only think of two options - epoxy and 3M Super 77
spray adhesive. All comments or suggestions are welcome.

Scotch 77 is basically rubber cement. A reversible glue. Lots of solvents
will break the bond. Water in not one. Oil ???  It is a soft line glue that
might allow the two layers to slide wrt each other.
Epoxy in its many compositions is a hard line glue with the ability to
provide structural gap filling. There is probably some chemical that will
dissolve it but it is considered a permanent glue. No solvents will work.
If you never would want to again separate the layers, why not use epoxy?
Bond once and get on with sharpening life.

I have used epoxy to repair a broken stone (JB Weld)  and its held up quite
well in infrequent use.  I'd think relaminating a stone would work fine.

Kirk in HMB, made a quick trip in and out of the garage to measure a tool
today.  Over the weekend I sharpened some chisels and gouges, clearing up
some messy spaces a tiny bit.
