epxoides can be diluted with acid before they set. you can clean your
hands and tools with lemon juice or vinegar. all oaks contain tannin
(tannic acid) which dilutes epoxy and makes the bond weaker. white oaks
(english and burr) are lower in tannin than red oaks. you can sometimes
eat the acorns from white oaks without boiling off (leaching out) the
acid, hence the common name of sweet oak. you will have less dilution with
white oak.

boatbuilders usually recommend roughing up the surface of oak before
bonding with epoxy resin. you should be able to brush on something
like a soda solution to netralize the acid although I've never heard of
boatbuildiers doing it.

Greetings group, I was wondering if anyone has had any trouble with epoxy
glue and white oak. I'm building several laminations here of thin white oak
to form frames, sheer clamps, stem etc. and I recently ran across something
in print that warned of glueing up oak in such a manner. So far it has been
trouble free for me but it seemed appropriate to ask the knowledge base at
this forum of their experiences before proceeding at full speed.

best regards, Mike Brannon,
