Adhesive - Ebony to Aluminum
Adhesive - Ebony to Aluminum
(OP)
I have a pair of these break-down chopsticks. Because they're cool.
http://www.montbell.us/products/disp.php?cat_id=12...
Actually, it's my second pair, and they have just suffered the same failure as the first.
The eating end is made from ebony.
The holding end from anodized aluminum.
The joint is also anodized aluminum, glued to the ebony.
The joint fails. The adhesive doesn't appear to bond well to the anodized finish.
Any suggestions for what to use for repair?

Also consider what is causing the failure in your adhesive selection, i.e. how are the chopsticks being cleaned etc. and could this be attacking the adhesive.
(Being a smart guy you probably thought about the above already.)

roughen the aluminium with sandpaper immediately before bonding

Further, I'll need a miniscule amount of whatever. Hard to justify buying $40-50 dollars of G-Flex in a 4 ounce size with no other immediate need.

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Ebony wood (of any of the listed varieties) is listed as an irritant. Seems like a funny thing to use on the mouth end of an eating utensil.

West Marine stores sell thse kits for about US $25 as well.
I suspect that surface prep is probably more important than the exact adhesive :)

Just make sure to sand both ends smooth & wet both surfaces prior to adhesion, then use large elastic bands to keep the joint tight for 24hrs. They say 2 hours but it more won't hurt it.
5 bucks at any hardware store.
