My problem is how to fix a brass nut inside the turned wooden piece that
(I can only call it a button) will go on the cap of a pepper grinder
(and the matching salt grinder). I've made a nut-shaped hole. I just
want to fix it neatly so it stays there. I'm thinking epoxy but would

Regular epoxy does not adhere to metal very well, if at all. Not only does
epoxy not stick to metal but it is brittle and can crack. However, there is
a special epoxy formulated especially for adhering to metal. It is called
"J. B. Weld". I have used this special epoxy to secure nuts to wood,
fiberglass, and other non-metals. It works very well, it doesn't crack, and
it can be ground and treated like metal, more or less. It can be found at
Home Depot or other such stores.
It helps to rough up the nut a bit with sandpaper before securing it in
place with the "J. B. Weld". I think this will work for you very neatly.
Epoxy works just fine on metal. Make sure the metal is grease free and
rough it up a little. I often saw grooves across the corners to add a
bit more bite. Don't use the 5 minute stuff - it can be brittle. Use a
15 minute or so epoxy.
One thing to watch for is the epoxy getting into the threads - bad
epoxy. Putting a piece of masking tape on the bottom of the nut (the
side that goes in the hole) will help the threads stay clean. Use
denatured alcohol to clean up the unhardened epoxy.

Devcon Plastic weld adheres to most metals as well as epoxy & is
considerably stronger according to the manufacturer.
I'd not rely on the adherence of the adhesive to the brass; rather,
I'd be sure to score the brass so the cement is geometrically keyed
into it by sanding, filing grooves, etc. Then the breaking strength
will be determined by the cement's strength, not how well the cement
adheres to the material.
Hex nut ? Cut a tight fitting recess and epoxy it in place. If it's
a turned round nut, then get some grooves filed in the sides first.
Epoxy bonds well to most metals, but brass is awkward. Degrease well
first, and clean with wire wool. Then use a good grade of epoxy, not 5

Epoxy by itself in this application is essentially useless since it won't
bond to the brass very well.
Having said that, epoxy is also the answer; however, you need to add some
micro-balloons to the epoxy to make a "mud" the consistency of say
Counterbore a hole in the wood to accept the nut and coat the c'bore with
epoxy allowing it to cure overnight.
Next day, fill the c'bore with thickened epoxy and suck nut into it with a
Allow to cure.
The hinges of hell will rust shut before that nut comes loose.
A WORD OF CAUTION:
Coat the screw threads with some candle wax if you ever expect to remove it.
DAMHIKT ! ! ! <G>.
BTW, forget the 5 minute epoxy.
IMHO, it is strictly garbage except for a temporary repair purposes.
