I’m a little confused if your thinking of setting wood into wood
bezels or metal? However I have had some experience using different
hardwood and carving beads for rings and pendants the like. I got my
hardwoods from lee valley, and from a company call black forest wood
company, both have websites and you can order online from them. I
started with pen blanks for turning fancy pens but you can get much
bigger pieces. I’m sure there are lots of other places though.
There are some things to take into consideration when using
hardwoods as any other material, there are some safety precautions to
take because of the dust and oils they give off. Search google or
whatever and enter the name of the wood +health risks. Some woods
will cause breathing problems, others are carcinogenic and what have
you, there will be charts telling you the characteristics and
possible risk and precautions to take with these things.
What I used to shape the wood was a carving knife, and my dremel
with diamond burrs to shape them and then I sanded them with fine
grit and then polished them with a little wax. I also wore a mask,
eye protection and kept my work area clean with a vacume/extraction.
To keep the colour in some of the woods I heard using armour-all
works wonders as does oils. Depending on how they are mounted you
will have to consider the finish and how much skin contact it will
have, as certain things off gas or might cause skin problems if not
treated right. I used olive oil on my rings because they end up
getting washed with your hands, then you can just reapply more later.
With that as long as the piece is cleaned and replenished there
shouldn’t be any issue with the oil going rancid I would think.
Anyways I hope this gives you some that will help you
conceive your pieces.
Best of luck,
